A truck bed is never quite long enough. A kayak, a ladder, a sheet of plywood or a load of lumber always overhangs by a foot or two, and the tailgate down is not a solution — it is a hope, and hope does not hold a load at highway speed.
A bed extender is the honest answer: a frame that flips out with the tailgate open to add up to two feet of enclosed cargo area, then flips back in to keep smaller cargo contained. The alternatives split by mount — tailgate or hitch — and by adjustability.
This guide reviews five extenders on maker evidence: three AMP Research BedXTenders, the Yakima LongArm hitch mount, and two adjustable aluminium tailgate extenders. Each review states the fit, the added length and the load, so the extender you buy fits the truck you own.
The 30-second answer
Buy the AMP Research BedXTender HD Max 74814 if you want the best tailgate extender: up to two feet of added cargo area, made in the USA. Buy the Yakima LongArm if you want a hitch-mounted extender for kayaks, lumber and ladders. Buy the VEVOR tailgate extender if you want an adjustable 55.5 in to 68 in aluminium frame. Buy the YZONA extender if you drive a midsize truck like a Colorado or Tacoma. Buy the KOKSHELY hitch extender if you want a 750 lb hitch-mounted rack with four positions.

How to choose a bed extender
Tailgate or hitch mount
A tailgate extender flips out with the tailgate and adds enclosed cargo area; a hitch extender mounts to the receiver and carries long loads. Tailgate extenders suit enclosed loads; hitch extenders suit kayaks, lumber and ladders.
Fitment: part number or adjustable
AMP makes a different BedXTender for each truck, so the part number decides the fit. Adjustable extenders like the VEVOR and YZONA cover a range of widths, but they need drilling. Measure the bed before ordering either way.
Added length
A tailgate extender adds up to two feet; a hitch extender adds up to four feet. Measure the load, not the bed: a kayak needs four feet, a sheet of plywood needs two.
Load capacity
A hitch rack rated at 750 lb carries more than one rated at 300 lb, and a tailgate extender’s rating is rarely published. Never exceed the lowest rating in the chain: extender, receiver, tailgate cables or load.
Drill or no-drill
AMP extenders are generally no-drill; the VEVOR and YZONA need holes in the bed walls or tailgate. Decide before ordering whether drilling is acceptable, because it cannot be undone.
Storage when not in use
A tailgate extender flips in and stays on the truck; a hitch extender removes and stores in the garage. If you use the extender weekly, a flip-in design wins; if monthly, a removable hitch rack wins.
Bed extender alternatives by budget
| Tier | What you get | Example pick |
|---|---|---|
| Low | An adjustable aluminium tailgate extender for a midsize truck | YZONA extender |
| Mid | A hitch-mounted extender for long loads, or an adjustable full-size tailgate extender | Yakima LongArm, VEVOR extender |
| Higher | The best-known tailgate extender, plus a high-capacity hitch rack for heavy loads | AMP HD Max, KOKSHELY hitch rack |
Types of a bed extender
| Type | How it works | Best for |
|---|---|---|
| Tailgate extender | Flips out with the tailgate, adds enclosed area | Full-size and midsize trucks, enclosed loads |
| Hitch extender | Mounts to the receiver, carries long loads | Kayaks, lumber, ladders |
| Adjustable tailgate extender | Length adjusts to the bed width | Owners who want one extender for many trucks |

Best Overall: AMP Research BedXTender HD Max 74814-01A
Best Overall
Why the AMP Research BedXTender HD Max 74814-01A is our pick
The AMP Research BedXTender HD Max 74814-01A is a black tailgate bed extender that flips out with the tailgate open to gain up to two feet of enclosed cargo area, and flips inside to keep tools and smaller cargo contained. It is made in the USA with global materials, and it is the HD Max version of AMP’s best-known extender.
It is the overall pick because it is the extender most truck owners know and trust: a simple flip design, a strong aluminium frame, and a fitment list that covers most full-size trucks. Owners in truck roundups call the HD Max the practical choice for maximising cargo space.
AMP Research BedXTender HD Max 74814-01A key specs

Best Hitch-Mounted: Yakima LongArm Hitch Mounted Bed Extender
Best Hitch-Mounted
Why the Yakima LongArm Hitch Mounted Bed Extender is our pick
The Yakima LongArm is a hitch-mounted adjustable truck bed extender made of aluminium, with three load-carrying positions and a capacity of 300 lb. It extends the usable length of the truck bed by up to four feet, for kayaks, lumber and ladders, and it fits a 2 in hitch receiver.
It is the hitch-mounted pick because it does what a tailgate extender cannot: it carries long loads at bed height, at bed-rail height or at cab height, and it works on any truck with a 2 in receiver. Owners in truck roundups call it the versatile choice for long loads.
Yakima LongArm Hitch Mounted Bed Extender key specs
- Part number: 8001149
- Added length: Up to 4 ft
- Capacity: 300 lb
- Positions: Three: bed, bed-rail and cab height
- Material: Aluminium
- Receiver: 2 in hitch
- Use: Kayaks, lumber, ladders
- Warranty: Not published
- Colour: Black
- Design: Hitch-mounted, adjustable
Yakima LongArm Hitch Mounted Bed Extender: fits and best for
Owners who haul kayaks, lumber and ladders and want a hitch-mounted extender that fits any truck with a 2 in receiver.
Yakima LongArm Hitch Mounted Bed Extender pros and watch-outs
Pros
- Adds up to four feet of bed length
- Three load positions
- Works on any truck with a 2 in receiver
- Aluminium, light for its size
Watch-outs
- 300 lb capacity is lower than some hitch racks
- Needs a 2 in receiver
- Blocks the tailgate when fitted
- Long loads need flagging and tie-downs
Yakima LongArm Hitch Mounted Bed Extender: what owners report
Owners in truck roundups describe the LongArm as the versatile choice for long loads, and note the three positions as the feature that makes it work for kayaks and lumber alike. Car and Truck best truck bed extenders
Truck owners report the aluminium build as light and the 300 lb capacity as enough for kayaks, ladders and lumber. ToolsNova aluminium truck bed extenders
Yakima LongArm Hitch Mounted Bed Extender: who should not buy
Do not buy it for heavy loads: 300 lb is the limit, and a heavier load needs a stronger hitch rack.
Yakima LongArm Hitch Mounted Bed Extender: pair it with
Pair it with tie-down straps and a red flag for overhanging loads, and a hitch pin lock.
We may earn a commission at no cost to you.
Tip: flag any load that overhangs the tailgate, and tie it at both ends — a long load that shifts is a hazard. See our best automotive borescope guide for receiver checks.
Best Adjustable Aluminium: VEVOR Truck Bed Extender
Best Adjustable Aluminium
Why the VEVOR Truck Bed Extender is our pick
The VEVOR truck bed extender is an aluminium tailgate extender with an adjustable length from 55.5 in to 68 in, a 180-degree flip design and 21 in of added loading space when flipped out. It fits Ford Super Duty, Dodge Ram, Toyota Tundra, Nissan Titan, Chevrolet Silverado and GMC Sierra trucks.
It is the adjustable pick because the length adjusts: one extender covers a range of truck widths, instead of one part number per truck. The drill-required install is the trade — this is not a no-drill extender — but the adjustable frame is the reason to buy it.
VEVOR Truck Bed Extender key specs
- Length: 55.5 in to 68 in adjustable
- Added space: 21 in when flipped out
- Material: Aluminium
- Design: 180-degree flip, retractable
- Fit: Ford Super Duty, Ram, Tundra, Titan, Silverado, Sierra
- Install: Drill required
- Model: TZJ-01-02
- Use: Ladders, wood, kayaks, UTVs
- Warranty: Not published
- Dimensions: 55.51 x 18.5 x 20.87 in
VEVOR Truck Bed Extender: fits and best for
Owners of full-size trucks who want one adjustable extender and will drill the bed for the install.
VEVOR Truck Bed Extender pros and watch-outs
Pros
- Adjustable length covers many trucks
- 21 in of added loading space
- Aluminium, light and strong
- 180-degree flip design
Watch-outs
- Drill required — not a no-drill install
- Universal fit needs careful measuring
- Heavier than a fixed AMP extender
- Load rating not published in the listing data captured
VEVOR Truck Bed Extender: what owners report
Owners in truck roundups describe the adjustable length as the feature that makes one extender fit many trucks, and note the drill install as the trade. Car and Truck best truck bed extenders
Truck owners report the 21 in of added space as the practical win for ladders and lumber, and warn to measure the bed width before ordering. ToolsNova aluminium truck bed extenders
VEVOR Truck Bed Extender: who should not buy
Do not buy it if you will not drill: this extender needs holes in the bed walls or tailgate, and a no-drill extender is the answer if drilling is not acceptable.
VEVOR Truck Bed Extender: pair it with
Pair it with a drill, a sealant for the holes, and tie-down straps for the load.
We may earn a commission at no cost to you.
Tip: measure the bed width at three points before ordering — truck beds are rarely square. See our best automotive borescope guide for bed checks.
Best for Midsize Trucks: YZONA Truck Bed Extender
Best for Midsize Trucks
Why the YZONA Truck Bed Extender is our pick
The YZONA truck bed extender is an aluminium tailgate extender with an adjustable length from 49 in to 61 in, a 180-degree flip design and 21 in of added loading space. It is made for small and midsize pickups: Toyota Tacoma, Nissan Frontier, Chevrolet Colorado, GMC Canyon, Ford Maverick and Hyundai Santa Cruz.
It is the midsize pick because it is one of the few extenders made for midsize trucks: the 49 in to 61 in range fits a Colorado or a Tacoma where a full-size extender will not. The drill-required install is the trade, as with the VEVOR.
YZONA Truck Bed Extender key specs
- Length: 49 in to 61 in adjustable
- Added space: 21 in when flipped out
- Material: Aluminium
- Design: 180-degree flip, retractable
- Fit: Tacoma, Colorado, Canyon, Frontier, Maverick, Santa Cruz
- Install: Drill required
- Part number: Y-BedExtend-0003-FBA
- Use: Ladders, lumber, kayaks, UTVs
- Warranty: Not published
- Colour: Black
YZONA Truck Bed Extender: fits and best for
Midsize truck owners — Colorado, Tacoma, Frontier, Canyon, Maverick or Santa Cruz — who want a tailgate extender that fits.
YZONA Truck Bed Extender pros and watch-outs
Pros
- Made for midsize trucks
- Adjustable 49 in to 61 in length
- 21 in of added loading space
- Aluminium, light and strong
Watch-outs
- Drill required — not a no-drill install
- Only fits midsize trucks
- Load rating not published in the listing data captured
- Needs the bed width measured first

Truck owners report the 21 in of added space as the win for kayaks and lumber on a midsize bed. The Motor Guy Ford F-Series bed extenders
YZONA Truck Bed Extender: who should not buy
Do not buy it for a full-size truck: the 49 in to 61 in range is too short, and a full-size extender is the answer.
YZONA Truck Bed Extender: pair it with
Pair it with a drill and sealant for the install, and tie-down straps for the load.
We may earn a commission at no cost to you.
Tip: choose the size by your bed width, not by the truck name — two Colorados can have different beds. See our best automotive borescope guide for bed checks.
Best Hitch Rack: KOKSHELY Adjustable Hitch Mount Bed Extender
Best Hitch Rack
Why the KOKSHELY Adjustable Hitch Mount Bed Extender is our pick
The KOKSHELY adjustable hitch-mount bed extender is a four-position hitch rack for kayaks, ladders, lumber and oversized cargo, with a 750 lb load capacity and reflective tape. It fits a 2 in hitch receiver and adjusts to four positions for different loads.
It is the hitch-rack pick because the capacity is the story: 750 lb is more than double the Yakima LongArm’s 300 lb, and the four positions cover bed height to cab height. The reflective tape is a safety detail the other hitch racks lack.
KOKSHELY Adjustable Hitch Mount Bed Extender key specs
- Capacity: 750 lb
- Positions: Four
- Mount: Hitch mount, 2 in receiver
- Use: Kayaks, ladders, lumber, oversized cargo
- Safety: Reflective tape
- Model: KK06022
- Warranty: Not published
- Material: Not published
- Fit: Truck and SUV with 2 in receiver
- Design: Adjustable, four-position
KOKSHELY Adjustable Hitch Mount Bed Extender: fits and best for
Owners who haul heavy long loads — lumber, ladders and kayaks — and want the highest-capacity hitch rack here.
KOKSHELY Adjustable Hitch Mount Bed Extender pros and watch-outs
Pros
- 750 lb capacity, highest here
- Four adjustable positions
- Reflective tape for visibility
- Fits trucks and SUVs with a 2 in receiver
Watch-outs
- Blocks the tailgate when fitted
- Heavy for a hitch rack
- Needs a 2 in receiver
- Long loads need flagging and tie-downs
KOKSHELY Adjustable Hitch Mount Bed Extender: what owners report
Owners in truck roundups describe the four-position design as the feature that fits kayaks, ladders and lumber alike, and note the 750 lb capacity as the figure that decides it. Car and Truck best truck bed extenders
Truck owners report the reflective tape as a safety win at night, and the adjustable positions as the practical detail. ToolsNova aluminium truck bed extenders
KOKSHELY Adjustable Hitch Mount Bed Extender: who should not buy
Do not buy it for light loads only: a 750 lb rack is heavy, and the Yakima LongArm is lighter and easier for kayaks alone.
KOKSHELY Adjustable Hitch Mount Bed Extender: pair it with
Pair it with tie-down straps, a red flag for overhanging loads, and a hitch pin lock.

Tip: set the height before loading, not after — a loaded rack is hard to adjust. See our best automotive borescope guide for receiver checks.

Installation and use basics
For a tailgate extender, confirm the part number against your exact truck, then fit the pivot brackets to the bed walls or the tailgate. For an adjustable extender, drill the holes the maker specifies, seal them, and fit the brackets. For a hitch extender, slide the shank into the 2 in receiver and pin it.
Set the height or the length before loading, not after: a loaded extender is hard to adjust, and a long load that shifts is a hazard. Tie the load at both ends, flag any overhang, and check the tailgate cables before every trip. Our best automotive borescope guide covers bed and tailgate checks, and our best automotive multimeters guide covers nothing electrical here — extenders are mechanical.
When the extender is not in use, flip a tailgate extender in and close the tailgate, or remove a hitch extender and store it in the garage. A hitch extender left in the receiver is a shin hazard and a theft risk.
Safety essentials
Safety essentials
- Never exceed the lowest rating in the chain: extender, receiver, tailgate cables or load.
- Flag any load that overhangs the tailgate, and tie it at both ends.
- Check the tailgate cables before every trip with an extender fitted.
- Set the height or length before loading, not after.
- Never drive with a hitch extender fitted and no load — remove it or stow it.
- Keep hands clear of the pivot points when flipping an extender.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Extender will not fit the bed | Wrong part number or wrong width | Confirm the part number or measure the bed width and buy an adjustable extender |
| Tailgate will not close | Extender flipped out, or brackets misaligned | Flip the extender in, then check the bracket alignment |
| Load shifts at speed | Tied at one end only | Tie the load at both ends and add a second strap |
| Hitch extender rattles | Pin worn or receiver loose | Replace the pin and check the receiver for wear |
| Drilled holes leak | Holes not sealed | Remove the brackets, seal the holes, and refit |
| Extender sags under load | Load exceeds the rating | Reduce the load or use a higher-capacity hitch rack |
Who should NOT buy these
Do not buy a bed extender without confirming the fit. AMP makes a different BedXTender for each truck, and an adjustable extender still needs the bed width measured. A wrong part will not fit, and returns on fitted parts are rarely simple.
Do not buy a drill-required extender if you will not drill. The VEVOR and YZONA need holes in the bed, and that cannot be undone. If drilling is not acceptable, buy a no-drill AMP extender or a hitch-mounted rack instead.
Do not buy on added length alone. A hitch extender that adds four feet is useless if its 300 lb capacity cannot carry your load, and a tailgate extender that adds two feet is useless if it does not fit your truck. Read the capacity and the fitment together.
Do not buy a hitch extender for a truck with no receiver. Hitch extenders need a 2 in receiver, and a truck without one needs a receiver fitted first — or a tailgate extender instead.
Final verdict
AMP Research BedXTender HD Max 74814-01A: the overall pick for full-size trucks.
Yakima LongArm Hitch Mounted Bed Extender: the hitch-mounted pick for long loads.
VEVOR Truck Bed Extender: the adjustable pick for full-size trucks.
YZONA Truck Bed Extender: the midsize-truck pick.
KOKSHELY Adjustable Hitch Mount Bed Extender: the hitch-rack pick for heavy long loads.
FAQ
What is the best truck bed extender?
The AMP Research BedXTender HD Max is the best tailgate extender: up to two feet of added cargo area, a proven flip design, made in the USA. For long loads, the Yakima LongArm hitch extender adds up to four feet, and the KOKSHELY hitch rack carries up to 750 lb.
How much length does a bed extender add?
A tailgate extender adds up to two feet of enclosed cargo area; a hitch extender adds up to four feet of bed length. The VEVOR and YZONA tailgate extenders add 21 in of loading space when flipped out.
Will a bed extender fit my truck?
It depends on the extender. AMP makes a different BedXTender for each truck, so confirm the part number. Adjustable extenders like the VEVOR fit 55.5 in to 68 in, and the YZONA fits 49 in to 61 in for midsize trucks — measure your bed width first.
Do bed extenders require drilling?
Some do, some do not. The VEVOR and YZONA adjustable extenders require drilling; AMP tailgate extenders are generally no-drill. Decide before ordering whether drilling is acceptable.
Can I use a bed extender with a tonneau cover?
It depends on the cover and the extender. A tailgate extender flips in and may clear a cover; a hitch extender sits behind the tailgate and usually does not interfere. Check both makers’ fitment notes before ordering.
What is the difference between a tailgate and a hitch bed extender?
A tailgate extender flips out with the tailgate and adds enclosed cargo area; a hitch extender mounts to the receiver and carries long loads like kayaks and lumber. Tailgate extenders suit enclosed loads; hitch extenders suit long loads.
How much weight can a bed extender hold?
A hitch rack like the KOKSHELY holds up to 750 lb; the Yakima LongArm holds 300 lb. Tailgate extender ratings are rarely published, so never exceed the lowest rating in the chain: extender, receiver, tailgate cables or load.
Do I need to flag a load on a bed extender?
Yes, if it overhangs the tailgate. Flag the end of the load, tie it at both ends, and check the flag before every trip — an unflagged overhang is a hazard and, in many places, an offence.
Can I leave a hitch bed extender in the receiver?
You can, but it is a shin hazard and a theft risk, and it blocks the tailgate. Remove it when not in use, or use a stowing mount like the B and W Tow and Stow for hitches. Store a removed extender in the garage.
