How we researched this guide
We compared 5 Ironman 4×4 underbody protection ranges and vehicle kits, checked 3 Ironman catalogue and dealer documents plus 4 maker and comparison sources, and reviewed owner and editorial reports from 3 build and guide sources. Every fitment and thickness claim below comes from one of those documents, linked in Sources, and no claim is presented as a test result we performed.
Where a current Ironman part number, weight, or warranty term was not printed in the sources we found, the article says so plainly instead of filling the gap. Ironman kits are sold through dealers, not as Amazon listings, so each pick also names a verified Amazon alternative with its own link, directly under the pick, for buyers who need a shipped plate for a US-market vehicle.
The 30-second answer
For most Hilux and LandCruiser touring use, the Ironman Premium 4mm steel range is the pick to start with, because it covers radiator, steering, engine and transmission with recessed hardware and service inspection holes. The standard 2.5 to 3mm range suits lighter touring and work utes where weight matters more than maximum strike resistance. Choose strictly by vehicle and year, check bull-bar and long-range tank compatibility before ordering, and use the Amazon alternative under a pick only when its listed fitment matches your vehicle.
Best Overall
Ironman Underbody Protection, Toyota Hilux
Best if you run a Hilux on rocky tracks and want full engine and transmission coverage in one vehicle-specific kit. Standard steel suits lighter use, while the Premium range is the stronger choice for repeated strikes.
Amazon alternative for US buyers: Rough Country Tacoma skid kit, ASIN B0DKGBHQK8. It does not fit a Hilux. It is listed here only for Tacoma owners who need a shipped plate.
Best for Heavy Touring
Ironman Underbody Protection, Toyota LandCruiser 200
Best if you tour loaded in a LandCruiser 200 and want the widest coverage for steering, sump, transmission and transfer case. The Premium 4mm construction is the natural match for a heavy wagon on rough tracks.
Amazon alternative for US buyers: Rough Country 4Runner skid kit, ASIN B0G3YJYL9Z. It does not fit a LandCruiser 200. It is listed here only for 4Runner owners who need a shipped plate.
Best Value
Ironman Underbody Protection, Toyota Prado 150
Best if you want Ironman coverage for a Prado wagon without stepping up to the thickest Premium plate on every panel. The standard range keeps weight down while still covering engine and transmission.
Amazon alternative for US buyers: ECOTRIC 4Runner and FJ Cruiser skid plate, ASIN B08M98MLYK. It does not fit a Prado 150. It is listed here only for 4Runner and FJ Cruiser owners who need a shipped plate.
Best for Work Utes
Ironman Underbody Protection, Ford Ranger and Everest
Best if you use a Ranger or Everest as a work and touring ute and want bolt-on engine and transmission protection, including the next-generation Everest kit coded UBP110.
Amazon alternative for US buyers: ECOTRIC Tacoma skid plate, ASIN B0D9QCB388. It does not fit a Ranger or Everest. It is listed here only for Tacoma owners who need a shipped plate.
Best for Navara and D-Max
Ironman Underbody Protection, Nissan Navara NP300
Best if you drive a Navara NP300 and want a kit with a named mounting kit, UBP048MK for UBP047, rather than a generic plate. The same family covers related D-Max and Colorado applications listed in the dealer sources.
Amazon alternative for US buyers: Dermon Tacoma skid plate, ASIN B0F62QP24J. It does not fit a Navara. It is listed here only for Tacoma owners who need a shipped plate.

How to choose Ironman underbody protection
Coverage first, thickness second
Start with what is actually exposed under your vehicle: radiator, steering, engine sump, transmission and transfer case. A single front plate leaves the gearbox and transfer case open, which is exactly where a rock strike can end a trip. Ironman Premium kits are described as covering radiator, steering, engine and transmission, so compare any kit panel by panel rather than by its headline thickness alone.
Material and thickness
Ironman standard plates are 2.5 to 3mm pressed and folded steel, and Premium plates are 4mm fabricated steel. Thicker steel resists a harder strike but adds weight and can transfer more force into mounts if it never gives at all. For repeated rock work, the Premium range is the logical choice. For gravel touring with occasional ruts, the standard range is a sensible balance.
Vehicle fitment and bull-bar match
Underbody kits are vehicle-specific, not universal. A Hilux kit does not fit a Ranger, and a Prado kit does not fit a LandCruiser 200, even though the steel looks similar. Check the front plate against your bull bar as well, because some front plates are made to marry up with a matching bar, and a mismatched bar can leave a gap or force a trim.
Ventilation, drainage and servicing
Plates need venting and water dispersion holes so heat can escape and mud and water can drain, and service inspection holes where the design allows them. Ironman states that plates should be removed when draining fluids, so plan servicing around that step. A kit that traps mud against the sump will cause corrosion problems even if it never takes a hard hit.
Weight and payload
A typical Ironman Premium kit is indicated at 25 to 30 kg in the 4×4 Australia guide, and older Prado 120 plates were listed at 26 kg for the engine plate and 12.5 kg for the transmission plate. That weight sits low, which helps stability, but it still counts against payload and suspension load on a fully laden tourer, so allow for it when you load the vehicle.
Corrosion and hardware
Recessed high-tensile hardware matters as much as plate thickness, because an exposed bolt head can shear off on a rock and then cannot be undone. Ironman Premium plates use fully recessed hardware and an EDP E-Coat layer under a textured powder coat. Once that coating is scraped through to bare steel, touch it up promptly, because steel will rust where the coating is gone.
Ironman fitment at a glance
| Vehicle | Years in catalogue | Range | Source |

| Nissan Navara NP300 | 2015 on | Standard, Premium | Dealer listing UBP047 |
Fitment years above are catalogue ranges, not a promise that every year and variant uses the same kit. Confirm the current UBP code, diesel or petrol variant, and any long-range tank conflict with a dealer before ordering.
Ironman underbody protection by budget
| Tier | What you get | Example pick |
|---|---|---|
| Standard steel | 2.5-3mm pressed and folded plates, bolt-on fit | Prado 150 standard kit |
| Premium steel | 4mm fabricated plates, recessed hardware, service holes | Hilux Premium kit |
| Full coverage | Engine plus transmission plus fuel tank where listed | LandCruiser 200 Premium kit |
| US shipped alternative | Amazon plate for a matching US vehicle only | Rough Country or ECOTRIC alternative |
No prices are shown in this guide, by site rule. Use the Check Price buttons for the Amazon alternatives, and ask an Ironman dealer for a fitted quote on the Ironman kit itself, including any mounting kit that is sold separately.
Types of underbody protection
| Type | Pros | Cons | Best for |
|---|---|---|---|
| Standard steel, 2.5-3mm | Lighter, bolt-on, proven | Less strike resistance | Gravel and light tracks |
| Premium steel, 4mm | Strongest Ironman range, recessed bolts | Heavier, steel can rust if gouged | Rocky touring |
| Aluminium alternative | Lighter, corrosion resistant | Can gouge, usually thinner cover | Weight sensitive tourers |
| Fuel tank plate add-on | Protects a vulnerable tank | Extra weight, tank conflicts possible | Remote touring |
Detailed reviews: Ironman underbody protection kits
Each kit below is judged on the same points: coverage, steel and finish, hardware and servicing, fitment limits, and what owners and editorial reports actually say. The Amazon alternative under each kit is not a substitute fitment for the Ironman vehicle.
Best Overall: Ironman Underbody Protection, Toyota Hilux
Best Overall — Hilux engine and transmission coverage
Why the Ironman Hilux kit is our pick
The Hilux is the vehicle most readers of this guide will actually drive off road, and Ironman lists it in both the standard and Premium ranges, for 2005 to 2015 and for 2015 on. That breadth matters, because a Hilux used for work and touring faces the same rocks as a dedicated tourer but is often driven loaded. The kit covers the parts that end a trip when they fail: the sump, the steering area, and the transmission. It is the most complete starting point in the Ironman range for a single-vehicle owner.
Ironman Hilux kit key specs
- Material: Steel, pressed and folded in the standard range, fabricated in the Premium range
- Thickness: 2.5 to 3mm standard, 4mm Premium
- Finish: Semi-gloss powder coat standard, textured powder coat with EDP E-Coat on Premium
- Coverage: Engine and transmission, with radiator and steering coverage on Premium kits
- Mounting: Bolt-on installation, no drilling stated for Premium kits in the comparison guide
- Hardware: Fully recessed high-tensile hardware on Premium kits
- Service access: Service inspection holes where appropriate, plates removed for fluid draining
- Ventilation: Venting and water dispersion holes positioned to protect airflow
- Design: Australian engineered and designed, CAD and FEA based
- Part number: Not published in the catalogue excerpts found, confirm with a dealer
- Weight: Not published per Hilux kit in the sources found, typical Premium indication 25 to 30 kg
- Warranty: Not published in the sources found
Ironman Hilux kit: fits and best for
This kit fits Toyota Hilux models in the catalogue ranges above, in diesel and petrol variants only as confirmed by a dealer for your year. It is best for Hilux owners who drive rocky tracks, station roads, and rutted touring routes, and who want protection that goes beyond the thin factory guard. Check bull-bar compatibility before ordering, because the front plate must meet the bar without leaving the radiator exposed, and check any long-range tank, which can conflict with a transfer case or tank plate.
Ironman Hilux kit pros and watch-outs
Pros
- Vehicle-specific Hilux fitment in two catalogue generations
- Premium 4mm option for repeated rock strikes
- Recessed hardware removes a common catch and shear point
- Service inspection holes help routine checks
- Bolt-on design avoids new holes in the chassis
Watch-outs
- No current UBP code printed in the excerpts found
- Steel can rust where the coating is scraped through
- Plates must come off for fluid draining
- Dealer ordering, not a shipped Amazon Ironman listing
Ironman Hilux kit: what owners report
Owner and editorial coverage for a single Hilux UBP code is thin, and this guide says so plainly. The reports found are broader: a 4×4 Australia ute review lists Ironman Premium Underbody Protection among the standard touring fitments on Hilux, Ranger and Triton test vehicles, which supports its place as a mainstream touring choice rather than a niche part. A separate Hilux guide warns that factory Hilux protection is good for one hard hit and then done, which matches the case for upgrading before rocky use. Readers should weigh those two points together: the kit is widely fitted, but no large owner sample for one code was found to quote.
Sources: 4×4 Australia ute accessories review and 4×4 Australia Hilux underbody guide.
Ironman Hilux kit: who should not buy
Do not buy this kit if you only drive sealed roads and light gravel, because the factory guard and careful driving will serve you, and the added weight is not justified. Do not buy it sight unseen for a modified Hilux with a non-standard bull bar or long-range tank until a dealer confirms clearance. If you need a plate shipped in the United States for a Tacoma, use the alternative below, not this Hilux kit.
Ironman Hilux kit: pair it with
Pair the kit with a recovery kit and rated recovery points, so a vehicle that does get hung up can be recovered without using the plates as a jacking point. See our recovery guide at https://winchinsider.com/best-winch-recovery-kit/ and our winch guide at https://winchinsider.com/best-off-road-winch/.
Amazon alternative, directly under this pick: Rough Country Skid Plate Kit for 2024-2026 Toyota Tacoma, 11-gauge steel with front and differential skids, ASIN B0DKGBHQK8. This alternative does not fit a Hilux. It is for Tacoma owners who need a US-shipped plate.
We may earn a commission at no cost to you.
Tip: Before fitting, photograph the factory guards and note any existing dents on the sump and crossmember, so you can tell after a trip whether a new mark came from a strike the plate absorbed. For fitting help, see https://winchinsider.com/how-to-install-a-winch-on-a-truck/.
Best for Heavy Touring: Ironman Underbody Protection, Toyota LandCruiser 200
Best for Heavy Touring — LandCruiser 200 wagon coverage
Why the Ironman LandCruiser 200 kit is our pick
A LandCruiser 200 is heavy, long, and often fully laden on remote tracks, so its underbody takes more strikes and each strike carries more force. Ironman lists the 200 in both ranges and in the fuel tank protection list, which makes a full-coverage build possible from one maker. The Premium 4mm plate, with its integrated framework, is the right match for that weight, because a thin plate on a heavy wagon will deform and can then press against the very component it was meant to protect.
Ironman LandCruiser 200 kit key specs
- Material: Steel, pressed and folded standard, fabricated Premium
- Thickness: 2.5 to 3mm standard, 4mm Premium
- Finish: Semi-gloss powder coat standard, textured powder coat with EDP E-Coat on Premium
- Coverage: Steering, front, sump and transmission, plus fuel tank protection listed separately
- Mounting: Bolt-on installation
- Hardware: Fully recessed high-tensile hardware on Premium kits
- Service access: Service inspection holes where appropriate, plates removed for fluid draining
- Ventilation: Venting and water dispersion holes
- Design: CAD and FEA based, Australian engineered and designed
- Part number: Not published in the catalogue excerpts found, confirm with a dealer
- Weight: Not published per 200 kit in the sources found, typical Premium indication 25 to 30 kg
- Warranty: Not published in the sources found
Ironman LandCruiser 200 kit: fits and best for
This kit fits Toyota LandCruiser 200 Series models as listed in the Ironman catalogue, subject to dealer confirmation for your year, engine, and any KDSS or suspension variant. It is best for loaded touring, towing, and remote travel where a sump or transmission failure would mean a long recovery. It is not a substitute for ground clearance: a 200 with a heavy load and standard suspension will still touch down, so drive to the clearance you have, not to the thickness of the plate.
Ironman LandCruiser 200 kit pros and watch-outs
Pros
- Full family coverage including fuel tank protection
- Premium framework spreads load into stronger elements
- Recessed hardware gives a smooth skid-over surface
- Service holes reduce the need for full removal on checks
- Proven catalogue fitment for a major touring wagon
Watch-outs
- No current UBP code printed in the excerpts found
- Added weight on an already heavy wagon
- Steel needs touch-up after gouging
- Long-range tank fitment must be checked first
Ironman LandCruiser 200 kit: what owners report
Direct owner reporting for a single LandCruiser 200 UBP code was not found in a large sample, and this guide does not invent one. The closest editorial evidence is the 4×4 Australia kit guide, which lists Ironman Premium at 4mm with service holes and recessed hardware and notes the rust risk if the steel is damaged on rocks. A LandCruiser 200 build guide in the same tradition notes that bash plates should be stronger than light factory panels and cover as many vital parts as possible, which is the standard this kit is judged against here. Treat the kit as a well-documented maker range with thin single-code owner coverage, not as a crowd-verified part.
Sources: 4×4 Australia underbody protection kits guide and Project 200 underbody protection guide.
Ironman LandCruiser 200 kit: who should not buy
Do not buy this kit if your 200 never leaves sealed roads, or if you have already fitted a long-range tank that conflicts with the transfer case or tank plate and you are not willing to change the order of fitting. If you drive a US-market 4Runner instead, the alternative below is the shipped option, not this 200 kit.
Ironman LandCruiser 200 kit: pair it with
Pair the kit with a winch and recovery kit suited to a heavy wagon, and with a maintenance routine that includes checking plate bolts after rocky trips. See https://winchinsider.com/best-truck-winches/ and https://winchinsider.com/winch-maintenance-checklist/.
Amazon alternative, directly under this pick: Rough Country Front and Belly Skid Plate Kit for Toyota 4Runner 2025-2026, 14-gauge steel with front and differential skids, ASIN B0G3YJYL9Z. This alternative does not fit a LandCruiser 200. It is for 4Runner owners who need a US-shipped plate.
We may earn a commission at no cost to you.
Tip: Torque and re-check plate bolts after the first rocky trip, because a plate that loosens will rattle and can wear its mounts. For sizing a recovery winch for a heavy vehicle, see https://winchinsider.com/what-size-winch-do-i-need/.
Best Value: Ironman Underbody Protection, Toyota Prado 150
Best Value — Prado wagon protection without excess weight
Why the Ironman Prado 150 kit is our pick
The Prado 150 is a family tourer as often as it is a dedicated off-roader, so weight and daily drivability matter alongside protection. The standard Ironman range gives that balance: 2.5 to 3mm steel, pressed ribs and folded reinforcements, in a vehicle-specific kit, with the Premium 4mm range available if your tracks get harder. Ironman also lists fuel tank protection for the Prado 150, so a buyer can start with engine and transmission plates and add tank coverage later without switching makers.
Ironman Prado 150 kit key specs
- Material: Steel, pressed and folded standard, fabricated Premium
- Thickness: 2.5 to 3mm standard, 4mm Premium
- Finish: Semi-gloss powder coat standard, textured powder coat with EDP E-Coat on Premium
- Coverage: Engine and transmission, fuel tank protection listed separately
- Mounting: Bolt-on installation
- Hardware: Fully recessed high-tensile hardware on Premium kits
- Service access: Service inspection holes where appropriate, plates removed for fluid draining
- Ventilation: Venting and water dispersion holes
- Design: CAD and FEA based, Australian engineered and designed
- Historical part evidence: Prado 120 engine plate IUP002E, 26 kg, and transmission plate IUP002T, 12.5 kg, older series only
- Current part number: Not published in the catalogue excerpts found, confirm with a dealer
- Warranty: Not published in the sources found
Ironman Prado 150 kit: fits and best for
This kit fits Toyota Prado 150 models as listed in the Ironman catalogue, subject to dealer confirmation for diesel or petrol, KDSS, and bull-bar variant. It is best for Prado owners who tour on gravel, sand, and moderate rocky tracks and want a real upgrade over factory guards without turning a family wagon into a competition truck. If you regularly drag the underbody on rock steps, choose the Premium range instead of the standard range for this vehicle.
Ironman Prado 150 kit pros and watch-outs
Pros
- Good weight balance in the standard range
- Fuel tank add-on available in the same range
- Pressed ribs add strength without excess thickness
- Vehicle-specific Prado fitment, not a universal plate
- Premium upgrade path without changing maker
Watch-outs
- Standard steel is not the hardest option for rock work
- Current UBP code not printed in excerpts found
- KDSS and bull-bar variants need dealer confirmation
- Plates must come off for fluid draining
Ironman Prado 150 kit: what owners report
Owner coverage for a single Prado 150 UBP code is thin, and the older Prado 120 installation documents are the only Ironman-specific weights found. Those documents show a substantial engine plate and a lighter transmission plate, which supports the general point that Prado protection is a two-part job, not a single front guard. Editorial guidance in the 4×4 Australia kit guide reinforces the same point: look for coverage, recessed bolts, and a finish that resists corrosion, all of which are present in the Ironman Premium description. No owner star rating or review text is used here, because none was verified.
Sources: Ironman Prado 120 installation instructions and 4×4 Australia underbody protection kits guide.
Ironman Prado 150 kit: who should not buy
Do not buy this kit if you want a single front-only guard and nothing else, because the value of this range is in engine plus transmission coverage together. Do not buy it for a US-market 4Runner on the assumption that Prado and 4Runner plates interchange; they do not, and the alternative below is the 4Runner option.
Ironman Prado 150 kit: pair it with
Pair the kit with side steps or rails if your sills are also exposed, and with a recovery kit for remote touring. See https://winchinsider.com/best-winch-for-toyota-4runner/ for a related Toyota recovery guide and https://winchinsider.com/best-winch-recovery-kit/.
Amazon alternative, directly under this pick: ECOTRIC Skid Plate for 2014-2022 Toyota 4Runner and 2009-2014 FJ Cruiser, aluminium, 1/4-inch thick, ASIN B08M98MLYK. This alternative does not fit a Prado 150. It is for 4Runner and FJ Cruiser owners who need a US-shipped plate.
We may earn a commission at no cost to you.
Tip: If your Prado has KDSS, tell the dealer before ordering, because sway-bar and clearance details can change which plate variant fits. For related underbody reading, see https://winchinsider.com/best-underbody-protection-diesel/.
Best for Work Utes: Ironman Underbody Protection, Ford Ranger and Everest
Best for Work Utes — Ranger and Everest bolt-on coverage
Why the Ironman Ranger and Everest kit is our pick
Ranger and Everest owners often buy one vehicle for work, family, and touring, so a kit that fits both nameplates from one range is practical. Ironman lists Ranger and Mazda BT50 from 2007 on and Everest from 2015 on, and the next-generation Everest has a named kit, UBP110 with mounting kit UBP110MK, for engine bay and transmission. That named code is a real advantage over the other picks, because it removes guesswork for Everest buyers. The SA 4×4 Ranger build also shows why this matters: the factory front plate was thin, and the gearbox sump behind it was exposed.
Ironman Ranger and Everest kit key specs
- Material: Steel, pressed and folded standard, fabricated Premium
- Thickness: 2.5 to 3mm standard, 4mm Premium
- Finish: Semi-gloss powder coat standard, textured powder coat with EDP E-Coat on Premium
- Coverage: Engine bay and transmission on UBP110, radiator and engine on Premium Ranger kits
- Mounting: Bolt-on installation, no drilling stated for Premium kits
- Hardware: Fully recessed high-tensile hardware on Premium kits
- Service access: Service inspection holes where appropriate, plates removed for fluid draining
- Ventilation: Venting and water dispersion holes
- Design: CAD and FEA based, Australian engineered and designed
- Part number: UBP110 and UBP110MK for next-generation Everest, engine bay and transmission
- Weight: Not published per Ranger or Everest kit in the sources found, typical Premium indication 25 to 30 kg
- Warranty: Not published in the sources found
Ironman Ranger and Everest kit: fits and best for
This kit fits Ford Ranger and Mazda BT50 models from 2007 on and Ford Everest from 2015 on, as listed in the catalogue, with UBP110 specifically for next-generation Everest. It is best for work utes and family SUVs that see station tracks, building sites, and touring routes where a sump strike would stop work as well as a holiday. Confirm whether your Ranger is a PX or PX II variant and whether a bull bar is fitted, because the front plate interface differs by bar.
Ironman Ranger and Everest kit pros and watch-outs
Pros
- Named Everest code UBP110 with its mounting kit
- Broad Ranger and BT50 catalogue coverage
- Premium 4mm option with integrated framework
- Recessed hardware for a smooth skid surface
- Build evidence shows a real factory gap it fills
Watch-outs
- Ranger generation and bar variant must be confirmed
- Steel can rust where coating is damaged
- Plates must come off for fluid draining
- Dealer ordering, not an Amazon Ironman listing
Ironman Ranger and Everest kit: what owners report
The strongest owner-style evidence for this pick is the SA 4×4 Ranger build, which found a single thin factory front plate and an exposed gearbox sump, then fitted an Ironman kit of front radiator, mid-engine, and rear gearbox plates in 4mm fabricated steel with integrated framework and recessed fasteners, with no drilling required. That build report is paraphrased here, not quoted, and it is a single vehicle, not a survey. The 4×4 Australia ute review also lists Ironman Premium Underbody Protection on its Ranger test vehicle, which supports the kit as a standard touring fitment for this platform.
Sources: SA 4×4 Ironman Black Ops Build Part 2 and 4×4 Australia ute accessories review.
Ironman Ranger and Everest kit: who should not buy
Do not buy this kit if you drive a US-market Ranger and assume the Australian PX kit fits it, because model years and underbody layouts differ and must be confirmed. Do not buy it if you need a plate tomorrow from Amazon; the alternative below is the US-shipped Tacoma option, not a Ranger fitment.
Ironman Ranger and Everest kit: pair it with
Pair the kit with a bull bar that matches the front plate and with rated recovery points, so the front of the vehicle is protected as a system. See https://winchinsider.com/best-winch-for-toyota-tacoma/ for a related pickup guide and https://winchinsider.com/best-off-road-winch/.
Amazon alternative, directly under this pick: ECOTRIC Front Skid Plate for 2016-2023 Toyota Tacoma, aluminium, powder-coated, ASIN B0D9QCB388. This alternative does not fit a Ranger or Everest. It is for Tacoma owners who need a US-shipped plate.

Tip: Fit the underbody kit before a long-range tank if you are planning both, because tank fitment can change which transfer case plate fits. For Jeep-related underbody reading, see https://winchinsider.com/best-underbody-protection-jeep-wrangler/.
Best for Navara and D-Max: Ironman Underbody Protection, Nissan Navara NP300
Best for Navara and D-Max — Named mounting kit coverage
Why the Ironman Navara NP300 kit is our pick
The Navara NP300 pick earns its place because its dealer listing names both the plate and its mounting kit, UBP047 with UBP048MK, and lists the exact compatibility: 2015-on Navara NP300 and Thai-built Renault Alaskan. That clarity is valuable for a buyer who has been burned by vague universal claims. The related UBP041 family covers D-Max, MU-X, and Colorado applications, so the same range serves a whole group of work utes with similar underbody risks.
Ironman Navara NP300 kit key specs
- Material: Steel, pressed and folded standard, fabricated Premium
- Thickness: 2.5 to 3mm standard, 4mm Premium
- Finish: Semi-gloss powder coat standard, textured powder coat with EDP E-Coat on Premium
- Coverage: Engine and transmission
- Mounting: Bolt-on installation, mounting kit UBP048MK for UBP047
- Hardware: Fully recessed high-tensile hardware on Premium kits
- Service access: Service inspection holes where appropriate, plates removed for fluid draining
- Ventilation: Venting and water dispersion holes
- Design: CAD and FEA based, Australian engineered and designed
- Part number: UBP047, mounting kit UBP048MK, Navara NP300 2015 on
- Related part: UBP041 and UBP041MK for D-Max, MU-X and Colorado family
- Warranty: Not published in the sources found
Ironman Navara NP300 kit: fits and best for
This kit fits Nissan Navara NP300 from 2015 on, and Thai-built Renault Alaskan from 2017 on, as listed by the dealer source. It is best for Navara owners who use the ute for work and touring and want a named, vehicle-specific kit rather than a plate that claims to fit everything. Check diesel variant and bull-bar fitment with a dealer, and confirm that the mounting kit is included in your quote, because it is listed as a separate code.
Ironman Navara NP300 kit pros and watch-outs
Pros
- Named plate and mounting kit codes
- Clear Navara NP300 compatibility range
- Related D-Max and Colorado family coverage
- Premium 4mm option for harder use
- Recessed hardware and service holes on Premium
Watch-outs
- Alaskan fitment is Thai-built only, check yours
- Mounting kit is a separate code, confirm inclusion
- Steel can rust where coating is damaged
- Plates must come off for fluid draining
Ironman Navara NP300 kit: what owners report
Owner coverage for a single Navara UBP047 code is thin, and this guide does not dress up dealer listings as owner reports. The useful evidence is indirect but real: the same Ironman Premium range is listed as a standard touring fitment in the 4×4 Australia ute review, and the kit guide praises recessed hardware and service holes while warning about rust if steel is gouged. For a Navara buyer, that means the design features are documented, while long-term owner feedback for this exact code should be sought from a dealer or owners club before ordering, and any dealer claim should be checked against the code above.
Sources: Car Mods Australia UBP048MK listing and 4×4 Australia underbody protection kits guide.
Ironman Navara NP300 kit: who should not buy
Do not buy this kit if you own a non-Thai-built Alaskan or an older Navara D40 and assume the NP300 code fits, because the dealer listing is specific. Do not buy it if you need a US-shipped plate for a Tacoma; the alternative below is for Tacoma owners only and does not fit a Navara.
Ironman Navara NP300 kit: pair it with
Pair the kit with a recovery kit and a winch suited to a mid-size ute, so recovery does not depend on a plate or a tow point that was never rated for it. See https://winchinsider.com/best-winch-recovery-kit/ and https://winchinsider.com/best-snatch-block-for-winching/.
Amazon alternative, directly under this pick: Dermon 8mm Front Skid Plate with sound insulation for 2016-2023 Toyota Tacoma, ASIN B0F62QP24J. This alternative does not fit a Navara. It is for Tacoma owners who need a US-shipped plate.
We may earn a commission at no cost to you.
Tip: Order the plate and its mounting kit together and keep both codes on your invoice, so a missing bracket does not stall a fitting day. For category browsing, see https://winchinsider.com/off-road-winch-recovery/underbody-protection/.

Buttons in these tables go to the Amazon alternative for each pick. Editorial judgement, not test results: the Hilux kit leads on breadth of fitment, the LandCruiser 200 kit leads on full-coverage touring, and the Ranger and Everest kit leads on named-code clarity.
Fitment and installation
Ironman underbody kits are described as easy bolt-on installations, and Premium kits are described as no-drill in the comparison guide. In practice, that means using factory mounting points and the supplied hardware, not cutting the chassis. Work on a flat surface with the vehicle supported safely, keep every bolt and bracket in order as you remove the factory guards, and do not force a plate that does not sit flat, because a forced plate will stress its mounts and may press on a hose or line. Check steering, suspension, and driveline clearance at full lock and full suspension travel before driving, and re-check bolts after the first rocky trip. Remember that Ironman recommends removing plates when draining fluids, so a service takes longer than it did with factory guards alone. If your vehicle has parking sensors, a bull bar, or a long-range tank, confirm those interfaces with the dealer, because a plate that fits a standard vehicle may not fit a modified one.

Safety essentials
Underbody protection does not make a vehicle invulnerable, and it does not replace safe recovery practice. Follow these rules on every trip.
- Never work under a vehicle supported only by a jack. Use rated stands on solid ground.
- Never use a skid plate as a jacking point or a recovery point unless the maker rates it for that use.
- Stand clear of a loaded recovery line, use a damper, and wear gloves when handling steel cable or rope.
- Never hook a recovery line back onto itself, and keep the required wraps on a winch drum.
- Inspect plates, bolts, and mounts after rocky trips, and touch up coating damage promptly.
- Follow your vehicle and winch manuals when they conflict with any general advice in this guide.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Rattle under the vehicle | Loose plate bolt or bracket | Re-torque hardware, check mounts |
| Plate scrapes on mild tracks | Low clearance, heavy load | Reduce load, choose a better line |
| Rust spots after a trip | Coating scraped to bare steel | Clean, dry, and touch up coating |
| Mud packed above plates | Blocked drainage holes | Remove plates, clean, refit |
| Overheating on slow tracks | Blocked airflow or vent holes | Clear vents, check cooling system |
| Service access blocked | Plate covers drain or filter | Remove plate for service, as maker directs |
Who should NOT buy these
Sealed-road drivers should not buy these kits. If your vehicle never leaves sealed roads and well-formed gravel, the factory guards are enough, and the weight, servicing time, and cost of a steel kit buy you nothing you will use.
Buyers who need a plate tomorrow from Amazon should not order an Ironman kit expecting Amazon delivery. Ironman kits are dealer-ordered. If you need a shipped plate for a US-market Tacoma or 4Runner, use the Amazon alternative named under the relevant pick, and check its fitment, not the Ironman fitment.
Owners of heavily modified vehicles should not order blind. A non-standard bull bar, long-range tank, suspension lift, or KDSS variant can change clearance and fitment. Get dealer confirmation in writing for your exact vehicle before paying.
Rock-crawling specialists should not expect any 3mm plate to be enough. For repeated hard rock contact, choose the Premium 4mm range or a dedicated competition guard, and accept that even then, driving line and clearance matter more than plate thickness alone.
Budget buyers who will skip maintenance should not buy steel plates. Steel that is gouged and left bare will rust. If you will not inspect and touch up the coating, a corrosion-resistant aluminium alternative may serve you better over time.

FAQ
What does Ironman underbody protection actually protect?
Ironman kits protect the radiator, steering, engine sump, and transmission on Premium kits, with fuel tank protection listed separately for some vehicles. The exact panels depend on your vehicle, so compare the kit panel by panel against your factory guards rather than assuming full coverage from the name alone.
Is Ironman underbody protection sold on Amazon?
No Ironman UBP Amazon US listing was found in the research for this guide. Ironman kits are sold through Ironman dealers and distributors. That is why each pick in this guide names a separate Amazon alternative for a US-market vehicle, and why the alternative fitment must be checked on its own listing.
What is the difference between standard and Premium Ironman plates?
Standard plates are 2.5 to 3mm pressed and folded steel with a semi-gloss powder coat. Premium plates are 4mm fabricated steel with an EDP E-Coat layer, a textured powder coat, integrated framework, fully recessed hardware, and service inspection holes where appropriate. Premium is the stronger choice for repeated rock strikes.
Will an Ironman Hilux kit fit a Toyota Tacoma?
No. Hilux and Tacoma underbody layouts differ by market and generation, and no source in this guide states interchangeability. Tacoma owners should use a Tacoma-specific plate, such as the Rough Country or ECOTRIC alternatives named in this guide, and confirm year and hybrid fitment on the listing.
Do Ironman plates need drilling?
Ironman standard plates are described as easy bolt-on installations, and Premium kits are described as no-drill in the comparison guide. That means factory mounting points are used. If a plate does not sit flat on your vehicle, stop and check fitment rather than forcing it or drilling a new hole.
How much weight do Ironman plates add?
A typical Premium kit is indicated at 25 to 30 kg in the 4×4 Australia guide. Older Prado 120 documents list 26 kg for an engine plate and 12.5 kg for a transmission plate. Per-kit weights for current UBP kits were not published in the sources found, so allow for the typical range when you load the vehicle.
Can I service my vehicle without removing the plates?
Service inspection holes help with checks, but Ironman recommends removing plates when draining fluids. Plan servicing around that step, and use the removal as a chance to clean mud from above the plates and inspect bolts and mounts.
Does underbody protection affect cooling?
It can if vents and drainage holes are blocked by mud, which is why Ironman plates include venting and water dispersion holes. Keep those holes clear, watch temperatures on slow tracks, and check the cooling system itself if temperatures rise, because a plate is rarely the only cause.
Should I fit underbody protection before a bull bar or long-range tank?
Check all three together before ordering any one of them. A front plate must meet the bull bar without a gap, and a long-range tank can conflict with a transfer case or tank plate. Fitting the underbody kit before a tank, where the maker advises that order, avoids rework and a plate that no longer fits.
