Suspension Bushings Review (2026): 6 Picks & Guide

How to choose suspension bushings

Polyurethane vs rubber: the real trade-off

Polyurethane bushings firm up handling and resist the oils and ozone that rot rubber, but they can transmit more vibration and need grease to stay quiet — Grassroots Motorsports owners report squeaking when a poly bushing runs dry, and quiet operation when it is greased. Rubber keeps the OE ride and is maintenance-free, but it cracks with age. Decide by what you value: precision and longevity, or stock comfort.

Match the bushing to the job

Shock eyes, control arms, steering racks, sway bars and trailing arms take different loads, and their bushings are not interchangeable. A shock-eye bushing like the Energy 9.8107G cures a worn shock mount; a rack bushing like the Energy 8.10101R cures wandering steering; a trailing-arm bushing like the MOOG K80668 cures rear-end clunks. Diagnose the symptom first, then buy the bushing that lives at that joint.

Universal vs vehicle-specific fitment

Universal bushings work only when your measurements match: bore, outer diameter and length. The 9.8107G lists its 5/8-inch ID, 1 to 1-1/8-inch OD and 1-7/16-inch length, so measure your shock eye before ordering. Vehicle-specific kits such as the Prothane 7-206-BL list maker-verified years and models; kits with retailer-only fitment claims, like the Energy 8.10101R, deserve a check against the maker’s application chart first.

Install reality: grease, shells and pressing

Polyurethane demands grease — many Energy and Prothane kits include it, and owners on the GRM forum say re-lubing occasionally is normal maintenance, not a defect. Some kits press into factory shells you must reuse (the Prothane 7-206-BL is sold “w/o shells”), so confirm your shells are serviceable before ordering. If you have no press and no shop nearby, a bolt-in or OE-style replacement like the MOOG K7352 is the friendlier weekend job.

Warranty honesty: maker vs seller vs dealer

Warranty terms in this category are messy. MOOG’s Amazon listing says “Limited Warranty”, a marketplace seller says 1 year, and MOOG retail partners advertise limited lifetime on chassis parts — all for the same K7352. Energy Suspension’s and Prothane’s warranty sheets were not found during research. Treat seller-page warranty lines as seller claims and buy from a source whose return terms you trust.

When a total kit beats buying piecemeal

If every rubber bushing on the car is the same age, replacing one joint at a time means repeated disassembly and repeated alignments. A total kit like the Prothane 12-2002 covers the NA Miata’s main suspension locations in one order. Piecemeal makes sense when one bushing is clearly the failure — a single K80668 for a clunking Civic trailing arm, for example — rather than a car-wide refresh.

Suspension bushings by budget

Buy the scope that matches your diagnosis. Replacing every bushing when only the sway-bar bushings are worn is overspending; replacing one bushing when all of them are cracked is doing the job twice. The guides linked in each review below carry the same honesty about scope.

Bushing material types

A note on the MOOG K7352 material conflict: Amazon’s listing says Rubber, an eBay seller of the same part number says Thermoplastic. Neither is the maker’s own spec sheet, so the review below prints both and lets the seller pages speak for themselves.

Detailed reviews: six bushings, one honest pick at a time

Every review below states what the listing and the maker documents actually say — part numbers, dimensions, materials and fitment — and flags what was not verifiable. Owner points are paraphrased from linked forums and listing reviews; where no product-specific owner report exists, the review says so.

Best universal shock bushing: Energy Suspension 9.8107G

Top pick.

Why the Energy Suspension 9.8107G is our pick

The 9.8107G earns the top pick because it is the most honestly documented bushing in this guide: the maker publishes the part number, the hourglass shock-eye style, the exact bore, outer diameter and length, and the universal fit. Energy’s own install instructions say you reuse factory sleeves and hardware, and owner reports on the Grassroots Motorsports forum describe this urethane as middle-of-the-road in firmness — firmer than OEM rubber without being harsh — provided it is greased.

Energy Suspension 9.8107G key specs

• Brand: Energy Suspension
• Maker part number: 9.8107G (G suffix = black)
• ASIN: B000CN9D3K
• Material: Polyurethane (Hyper-Flex per maker boilerplate)
• Style: Hourglass shock eye bushing
• Inner diameter: 5/8 in
• Outer diameter: 1 in to 1-1/8 in
• Length: 1-7/16 in
• Sold as: Pair
• Hardware: Bushing only — reuse factory sleeves/hardware per Energy install instructions
• Country of origin: USA (per maker-manual record of the same listing family)
• UPC: 703639414308

Energy Suspension 9.8107G: fits and best for

Universal — the listing states “Universal, Pair”. Do not claim vehicle-specific fitment. Best for replacing a worn hourglass shock-eye bushing on any shock whose bore matches the published dimensions. Hourglass style only fits shocks with hourglass eyes, so confirm bore dimensions before ordering. If your suspension job includes a winch install, our truck winch install guide shows the access you already have with the front suspension apart.

Energy Suspension 9.8107G: what owners report

Energy Suspension 9.8107G: who should not buy

Skip this one if your shock eyes are not hourglass style, or if you want a bolt-in kit with new hardware — this box holds bushings only. Owners who will not grease poly bushings should look at the rubber alternative below: MOOG K7352.

Energy Suspension 9.8107G: pair it with

Pair it with a poly-safe grease supply and the rest of your shock hardware inspected — Energy’s instructions assume your factory sleeves are serviceable. While the suspension is apart, our winch maintenance checklist covers the recovery gear that lives near the same real estate.

Tip: Measure the shock-eye bore with calipers before ordering — universal only works when your numbers match the 5/8-inch ID, and a five-minute measure beats a return. See our sizing guide for how measurement-first thinking pays off elsewhere on the truck.

Best steering-rack bushing: Energy Suspension 8.10101R

Steering fix.

Why the Energy Suspension 8.10101R is our pick

The 8.10101R is the pick for a specific, common complaint: loose, wandering steering on a Toyota truck caused by collapsed rack bushings rather than the steering rack itself. Energy’s poly rack bushings tighten steering response, and IH8MUD owners describe the swap as a driveway-friendly fix for the exact symptom. The caveat is explicit: the retailer-reported fitment years were never confirmed against Energy’s own application chart, so the review prints that as an unverified lead.

Energy Suspension 8.10101R key specs

• Brand: Energy Suspension
• Maker part number: 8.10101R (R suffix = red; black would be 8.10101G)
• ASIN: B004ALJBXW
• Material: Polyurethane (Hyper-Flex)
• Type: Power steering rack bushing set
• Color: Red
• Item weight: 12.7 oz
• Package dimensions: 4 x 3.5 x 5.38 in
• Hardware: Reuse factory sleeves, bolts and washers (per maker install notes)
• Effect: Tightens steering response; can transmit slightly more vibration than rubber — the standard poly-for-rubber trade-off

Energy Suspension 8.10101R: fits and best for

Retailer-reported fitment: a Toyota steering-rack-bushing buying guide lists Energy kit 8.10101G/R as fitting 1st-gen Tacoma and 3rd-gen 4Runner (about 1995–2000). This is NOT maker-verified — Energy’s own application chart was not reached during research. Confirm your years against the maker’s chart before ordering; do not treat the range as fact. Toyota-truck owners should also read our Tacoma winch guide and 4Runner winch guide when the front end is already apart.

Energy Suspension 8.10101R: pros and watch-outs

Energy Suspension 8.10101R: what owners report

Energy Suspension 8.10101R: who should not buy

Skip this if your steering looseness comes from tie rods, ball joints or the rack itself — bushings only fix bushing wear. Owners unwilling to confirm fitment against the maker’s chart should hold off and read our general info guide first.

Energy Suspension 8.10101R: pair it with

Pair it with a front-end inspection before you order: check tie-rod ends and ball joints while the truck is up, because no bushing fixes a worn joint. Our Tacoma winch guide covers the recovery side of the same truck.

Tip: Press the bushing halves together with a long bolt and a stack of washers — the IH8MUD owners’ trick — and do the fiddly rear bushing below the oil pan first, while you still have patience.

Best total kit (Miata): Prothane 12-2002 Total Kit

Total kit.

Why the Prothane 12-2002 Total Kit is our pick

The 12-2002 is the pick for the NA Miata owner doing a proper refresh: Prothane’s own 2012 catalog lists it as the “Total Kit” for the 1990–1997 Miata, i.e. the maker-verified one-box answer for the car’s main suspension bushing locations. That maker-verified application line is rare in this category and is exactly why it outranks the piecemeal options for a same-age fleet of worn bushings. The honest caveat: the tracker last recorded it in September 2020, though third-party data is much newer — confirm it is live on the listing before planning the job around it.

Prothane 12-2002 Total Kit key specs

• Brand: Prothane
• Maker part number: 12-2002 (red)
• ASIN: B003AVUJKM
• Material: Premium-grade polyurethane
• Type: Total Kit — combined kit covering the car’s main suspension bushing locations
• Maker-verified fitment: 1990–1997 Mazda Miata (NA), per Prothane 2012 catalog
• Color: Red
• UPC: 636169185625
• Design: Precision fabricated for fit; designed to hold grease for quiet operation (maker catalog)
• Availability note: Price-tracker last recorded Sep 2020; third-party data recorded Feb 2024 and Aug 2025 — confirm on the live listing

Prothane 12-2002 Total Kit: fits and best for

Maker-verified: 1990–1997 Mazda Miata (NA) only — do not extend to NB Miatas. Best for a full poly conversion of a Miata whose stock rubber is tired. Doing every bushing is a big job; GRM owners call it the kind of project you do once, properly. If you also tow that Miata behind a truck, our car-trailer winch guide is worth a look.

Prothane 12-2002 Total Kit: pros and watch-outs

Prothane 12-2002 Total Kit: what owners report

Prothane 12-2002 Total Kit: who should not buy

Skip this if you own anything other than a 1990–1997 Miata, or if the listing shows it unavailable — do not substitute a different Prothane kit number by guessing. Single-bushing jobs belong to the single-bushing picks reviewed above.

Prothane 12-2002 Total Kit: pair it with

Pair it with a fresh alignment booking for after the install — a full bushing refresh changes geometry, and skipping the alignment wastes the job. Our maintenance checklist covers the recovery gear that shares the garage.

Tip: Order only after the live listing confirms the kit is in stock — the tracker history shows gaps — and do not print or promise a piece list the maker’s catalog text did not enumerate.

Best GM-truck control-arm kit: Prothane 7-206-BL

Truck pick.

Why the Prothane 7-206-BL is our pick

The 7-206-BL is the pick for 1988–1998 GM full-size 4WD pickups and 1992–1999 full-size Blazer, Suburban and Tahoe 4WD models — a maker-catalog-verified control-arm bushing kit in black poly. It earns the slot because the application range comes from Prothane’s own catalog, not a retailer guess. The honest price of admission is spelled out: the kit is sold without shells, so you press the new bushings into your factory outer metal shells and confirm those shells are serviceable first.

Prothane 7-206-BL key specs

• Brand: Prothane
• Maker part number: 7-206-BL (BL suffix = black)
• ASIN: B003AVZRU4
• Material: Premium-grade polyurethane
• Type: Front control arm bushing kit, w/o shells — reuse factory outer metal shells
• Maker-verified fitment: 1988–1998 GM full-size 4WD pickups (1/2, 3/4, 1-ton); 1992–1999 full-size Blazer, Suburban, Tahoe 4WD (1/2-ton)
• Color: Black
• Design: Holds grease for quiet operation; provides rigidity (maker catalog)
• Install: Press required; confirm factory shells are serviceable before ordering
• Warranty: Not verified — omitted, never guessed

Prothane 7-206-BL: fits and best for

Maker-verified for the GM full-size 4WD lines above; do not claim other GM lines. Best for a truck whose control-arm bushings are the diagnosed wear point and whose owner has press access. Truck owners pairing suspension work with recovery gear should read our truck winch guide and install guide while the front end is accessible.

Prothane 7-206-BL: what owners report

Prothane 7-206-BL: who should not buy

Skip this if you have no press access, or if your factory shells are corroded or cracked — a press-in kit cannot fix dead shells. Bolt-in shoppers should look at the MOOG K7352 instead, and read our info guide before choosing.

Prothane 7-206-BL: pair it with

Pair it with a shop press session and a shell inspection before you order — if the shells fail the inspection, the right purchase is a full control arm, not this kit. Our budget truck winch guide keeps the truck-side budget honest while you are at it.

Tip: Inspect the factory shells for rust and cracks before the kit arrives — discovering dead shells mid-job with the truck on stands is the expensive version of this lesson.

Best OE-style rubber kit: MOOG K7352

OE-style.

Why the MOOG K7352 is our pick

The K7352 is the pick for drivers who want their Wrangler to ride like a Wrangler — rubber, OE-style, no greasing schedule, no added harshness. It is a 4-piece front sway-bar bushing kit whose Amazon listing names the part number, the Jeep Wrangler fit and the 4-piece count. It also carries this guide’s most explicit conflicts: Amazon says the material is rubber while an eBay seller says thermoplastic, and warranty lines range from 30 days to limited lifetime depending on the seller. Both conflicts are printed as conflicts below.

MOOG K7352 key specs

• Brand: MOOG (MOOG Chassis Products)
• Maker part number: K7352
• ASIN: B000C57YQQ
• Material: CONFLICT: Amazon listing says Rubber; an eBay seller says Thermoplastic
• Type: Suspension stabilizer (sway) bar bushing kit — 4 pieces
• Position: Front
• Fitment: Amazon title: “for Jeep Wrangler” — exact year range NOT confirmed; confirm against MOOG’s catalog
• Color: Black
• Item weight: 0.3 lb
• UPC: 080066317656
• Warranty: CONFLICT: Amazon says “Limited Warranty”; an eBay seller says 1 year; MOOG retail partners advertise limited lifetime on chassis parts — terms vary by seller
• Origin: Made in USA (per the eBay seller’s item specifics)

MOOG K7352: fits and best for

Amazon titles it for the Jeep Wrangler; the exact year range was not confirmed during research, so do not treat any range as fact — check MOOG’s catalog for your Jeep. Best for a Wrangler owner refreshing the front sway-bar mounts who wants the OE-style feel. Jeep owners should also see our Jeep winch guide and budget Wrangler winch guide.

MOOG K7352: who should not buy

Skip this if you want polyurethane’s firmer handling — the whole point of this kit is staying rubber. Skip it too if a seller cannot confirm your Wrangler’s year; an unconfirmed year range is not a fitment. The poly alternative on this page is Energy Suspension 9.8107G.

MOOG K7352: pair it with

Tip: Match the sway-bar diameter to the bushing before ordering — sway-bar kits are diameter-specific, and the listing does not publish one, so verify on the live page.

Best trailing-arm bushing: MOOG K80668

Honda pick.

Why the MOOG K80668 is our pick

The K80668 is the pick for the cheapest real fix on this page: a single trailing-arm bushing for older Honda Civics, the part that cures the rear-end clunk when the OE bushing disintegrates with age. TheHondaForums owners describe exactly that failure mode — and note that OE bushings were sometimes unavailable except as a full arm assembly, which is what makes the aftermarket bushing the smart buy. The honest arithmetic: unit count is one, and a job typically needs two.

MOOG K80668 key specs

• Brand: MOOG (MOOG Chassis Products)
• Maker part number: K80668
• ASIN: B00180G366
• Material: Rubber bushings (per Amazon “Material Type”)
• Type: Suspension trailing arm bushing
• Unit count: 1 — a single bushing; a job typically needs 2
• Fitment: Amazon title: “for Honda Civic”. Interchange data (Dorman 905-750 via newparts.com) lists Civic 1988–1995 (1.5L), Civic 1988–2000 (1.6L), CRX 1988–1991, del Sol 1993–1997, CR-V 1997–2001, Integra 1994–2001, MDX 2001–2006, Pilot 2003–2007 — interchange-reported, NOT maker-verified
• Item weight: 1.6 lb
• UPC: 080066366111
• Maker line: MOOG Problem Solver: “proven design and engineering features for like new steering, ease of installation and longer life” (maker’s marketing on the listing)
• Warranty: CONFLICT: Amazon says “30 Days”; MOOG retail partners advertise limited lifetime on chassis parts — terms vary by seller

MOOG K80668: fits and best for

Honda Civic per the Amazon title, with a wider interchange list above that is retailer-reported, not maker-verified — confirm against MOOG’s catalog before printing a range as fact. Best for curing a diagnosed trailing-arm bushing failure; remember you will usually need two of them. If your garage also services an ATV, our ATV winch install guide is the next read.

MOOG K80668: who should not buy

Skip this if you have not diagnosed the trailing arm as the fault — rear clunks have many causes. And order two, not one, unless you have confirmed only one side needs it; see our maintenance checklist for how we think about paired wear items.

MOOG K80668: pair it with

Tip: Order the quantity the job needs, not the listing’s unit count: this listing is one bushing, and doing one side of a paired wear item is doing half the job.

Spec comparison

No score row: these are commodity bushings, not ranked by an editorial rubric — the verdict below carries the recommendation as editorial judgement, not test results.

Fitment & installation basics

Bushing work rewards preparation and punishes assumptions. Verify fitment before you order: universal bushings demand your own measurements (bore, outer diameter, length), and vehicle-specific kits deserve a check against the maker’s own application chart — retailer fitment claims, like the years listed for the Energy 8.10101R, are leads, not facts. Kits sold “w/o shells” need your factory outer metal shells to be straight and serviceable; discover a corroded shell mid-job and the truck stays on stands. Torque suspension and steering fasteners to the factory specification with the suspension loaded, because tightening at full droop preloads the bushing. Grease every polyurethane bushing at install with a poly-safe grease, keep old hardware organized if the instructions say to reuse it, and book an alignment after any control-arm or total-kit job. While the front suspension is apart, it is the natural moment to route a winch install — our truck winch install guide and front-bumper mounting guide show the access you gain, and the budget truck winch roundup keeps the added spend honest.

Troubleshooting

Who should NOT buy these

The soften-the-ride crowd. Polyurethane firms things up; if you bought the truck for its stock comfort and just want the clunk gone, the rubber MOOG K7352 or K80668 is your lane, not the poly kits — and our essential accessories guide is the calmer upgrade path.

Maintenance-averse owners. Poly bushings need grease at install and re-lubing over time; owners on the GRM forum are explicit that running dry brings the squeak. If greasing suspension parts sounds like a chore, stay rubber and stay happy.

Anyone guessing at fitment. Universal means measure-yourself, and retailer-listed years mean verify-with-the-maker. Ordering the Energy 8.10101R or a Prothane kit on a hunch is how the wrong part arrives on a Friday night — see our info guide for the measure-twice approach.

Owners replacing one bushing when the whole corner is shot. A single K80668 fixes a diagnosed trailing-arm failure; it does not resurrect a corner where ball joints, tie rods and links are all tired. Diagnose the corner, then choose the scope — our maintenance checklist applies the same paired-wear thinking to recovery gear.

FAQ

Are polyurethane bushings better than rubber?

Neither is universally better — they trade different things. Polyurethane resists oils and ozone, lasts longer than aged rubber and sharpens handling, per the maker catalogs. Rubber keeps the stock ride and needs no maintenance. Choose poly for precision and longevity, rubber for factory comfort.

Do polyurethane bushings squeak?

They can when they run dry, and owners on the Grassroots Motorsports forum name squeaking as the recurring complaint with under-greased bushings. The same owners report the bushings stay silent when greased with the included grease or a synthetic grease, with occasional re-lubing as normal maintenance.

Can I mix polyurethane and rubber bushings on the same car?

Yes — this is common. Many owners convert the high-load locations to poly (control arms, rack) and leave rubber where comfort matters. The reviews above note the trade-off per location, so mix by job, not by brand loyalty.

Are universal shock bushings safe to use?

They are safe when your measurements match the published dimensions — bore, outer diameter and length. The Energy 9.8107G publishes all three. What is not safe is assuming: a bushing that is close but not exact can walk out or bind, so measure with calipers before ordering.

Do I need a press to install bushings?

Some kits do, some do not. The Prothane 7-206-BL presses into reused factory shells, so press access is mandatory. Bolt-on kits like the MOOG K7352 sway-bar kit are a hand-tools job. The review for each kit above states which kind it is.

What grease should I use on poly bushings?

Use a poly-safe grease — the kits often include one, and owners report synthetic greases work for re-lubing. Do not use a petroleum grease that can attack polyurethane. Grease at install and re-lube on the schedule the maker gives.

How often should suspension bushings be replaced?

There is no mileage rule that holds for every car. Rubber bushings crack with age and mileage; poly bushings last far longer but want grease. Replace on condition: cracking, clunks, wandering steering or visible deformation — not on a calendar.

Is a total kit worth it over buying one bushing?

When every bushing is the same age and equally tired, a total kit like the Prothane 12-2002 saves repeated disassembly and repeated alignments. When one joint is clearly the failure, buy the single bushing — the MOOG K80668 exists for exactly that job.

Will poly bushings void my vehicle warranty?

No bushing part number was found with a published maker warranty in this research, and warranty effects depend on the vehicle maker and the dealer. Keep your receipts, keep the old parts, and ask the dealer before a warranty-sensitive job.
