Best Independent Rear Suspension Kit for ATVs and UTVs

#1 · Best Overall

1. TUSK Rear Independent Kit

• Dimensions: 12 x 5.5 x 1 in
• Weight: 1.19 lb

Best for: One-side ATV rebuild service.

Why it ranks #1: Specifies a one-side rebuild with upper and lower A-arm and knuckle parts, plus thermoplastic bushings, precision-ground bearings, and double-lip seals.

A complete set of parts to rebuild one side of an ATV or UTV rear independent suspension distinguishes the TUSK kit from a single-component replacement. It covers the upper and lower A-arm and knuckle, while self-lubricating thermoplastic bushings and Teflon-lined spherical bearings support a service-focused repair on compatible machines.

TUSK includes the upper and lower A-arm and knuckle parts required for one side, which gives a mechanic a defined scope for the rebuild rather than just one suspension component. Its self-lubricating thermoplastic resin bushings support ongoing movement, while precision-ground spherical bearings with Teflon liners provide another specified bearing component. Hardened, plated bushings and double-lip Type TC seals address durability and sealing. The listing names King Quad 500AXi and 750AXi fitments and points to a fitment guide for additional machines.

Skip it if you need a two-sided rear suspension rebuild from one kit; this TUSK package explicitly covers one side only.

This suits Suzuki King Quad owners matching the listed 500AXi or 750AXi applications who are servicing one rear side. Its components and sealing details suit a focused rebuild, but the stated package scope does not cover both sides.

#2 · Best Suzuki Fit

2. All Balls Suzuki 50-1075 Kit

• Dimensions: 6.5 x 4.5 x 2.1 in
• Weight: 1.75 lb

Best for: Suzuki King Quad one-side rebuild.

Why it ranks #2: Lists Suzuki LT-A500X and King Quad 750 applications and supplies needle bearing shafts, bushings, washers, and seals for one-side rebuilding.

Five needle-bearing shafts and ten Delrin bushings give the All Balls Suzuki kit a clearly itemized component set for rebuilding one side of an ATV rear suspension. Its listing also specifies washers and seals, helping a buyer understand the repair scope before servicing a compatible LT-A500X or King Quad application.

The package contains five needle-bearing shafts, ten Delrin bushings, ten washers, and twenty seals, alongside upper and lower A-arm and knuckle components. That detailed inventory supports planning a one-side rebuild and shows the range of pieces supplied. The listing describes the acetal bushings as self-lubricating and the bushings as case hardened and plated for corrosion prevention. Applications include Suzuki LT-A500X and specified LT-A750X King Quad versions, with power-steering variants separately named.

Skip it if you are rebuilding both rear sides with a single kit; the listed package covers one side only.

This fits Suzuki owners servicing one side of a listed LT-A500X or LT-A750X King Quad. Its itemized shafts, bushings, washers, and seals help define the work, but buyers should account for the one-side scope.

#3 · Broad Polaris Fit

3. All Balls Polaris 50-1135 Kit

• Dimensions: 23 x 5.5 x 2 in
• Weight: 1 lb

Best for: Broad Polaris ACE and Ranger fitment.

Why it ranks #3: Covers numerous Polaris ACE and Ranger applications, including Ranger 1000 Diesel models, with fitment listed across several model years.

A long list of Polaris ACE and Ranger applications makes this All Balls rear independent suspension kit useful for owners matching a specific machine across several model years. It is stated to meet or exceed OEM specifications for fit and performance, connecting the replacement purpose to a defined standard rather than an unspecified upgrade claim.

The application list covers ACE variants from 325 through 900 and Ranger 1000 Diesel, 325 ETX, and other named models, giving owners several model families to check against their machine. All Balls states that the kit meets or exceeds OEM specifications for fit and performance, a relevant benchmark for a replacement part. Some applications separate EU, HD, MD, Crew, and EPS versions, so the trim designation can affect selection. The supplied details do not describe included pieces or installation steps.

Skip it if you own a Polaris outside the supplied ACE and Ranger applications; the listing does not establish fitment for every Polaris machine.

This is aimed at Polaris ACE or Ranger owners whose exact year and trim appear in the application list. Its OEM-spec claim is relevant for replacement shopping, but variant distinctions make precise machine identification important.

#4 · Wear-Resistant Parts

4. All Balls Polaris 50-1115 Kit

• Dimensions: 5 x 7.9 x 2.4 in
• Weight: 1 lb

Best for: Polaris Ranger and 900 applications.

Why it ranks #4: Lists Polaris Ranger applications and describes self-lubricating nylon bushings plus hardened, precision-ground needle bearing shafts.

Hardened, precision-ground bearing-steel needle-bearing shafts and self-lubricating acetyl nylon bushings define this All Balls Polaris kit’s component approach. The listing says it meets or exceeds OEM specifications for fit and performance, while its application description names Polaris Ranger and other model variants across specific years.

The bearing-steel shafts are hardened and precision ground, a specified construction detail for the kit’s needle-bearing shafts. Self-lubricating acetyl nylon bushings are described as offering better wear protection, linking their material to service use. All Balls also states that fit and performance meet or exceed OEM specifications. The application description includes Polaris LSV Electric and Ranger 2×4 500 examples, with build-date distinctions for some 2007 units; checking the exact machine details matters before selecting this replacement.

Skip it if you need fitment for a Polaris model not named in the application list; this listing identifies specific models, years, and build dates.

This suits a Polaris owner matching a listed Ranger or other application who values the stated OEM-spec fit claim and specified bearing materials. Pay close attention to model, year, and any listed build-date distinction before selecting it.

#5

5. All Balls Polaris 50-1112 Kit

• Dimensions: 23 x 5.5 x 2 in
• Weight: 3 lb

Best for: Polaris Sportsman 335 service.

Why it ranks #5: Targets older Polaris Sportsman 335, 400, and 500 4×4 applications, with specific model years and build-date distinctions listed.

A Polaris-specific rear independent suspension kit for the Sportsman 335 gives owners of the listed 1999–2000 machines a defined aftermarket replacement option. Its application list also names select Sportsman 400 and 500 variants, including build-date distinctions, helping narrow the search to particular Polaris fitments rather than a universal suspension part.

All Balls identifies this as a brand-new aftermarket unit, while the application description names Sportsman 335 models from 1999–2000 and select Sportsman 400 and 500 fitments. That model-by-model coverage gives owners a concrete starting point when matching a replacement to a machine. The 2001 Sportsman 400 entries distinguish units built before and after December 7, 2000, so that production detail matters during selection. The listing does not specify the kit’s included pieces or installation procedure.

Skip it if you need a kit confirmed for a Polaris model outside the listed Sportsman applications; this listing names particular models and years.

This suits a Polaris owner servicing a listed Sportsman 335, or a specifically named 400 or 500 variant. Check the exact model year and, for 2001 Sportsman 400, its build date before choosing this application-specific replacement.

#6

6. MOTO1988 Yamaha Knuckle Kit

Best for: Yamaha knuckle replacement.

Why it ranks #6: Fits a wide set of Yamaha Grizzly, Rhino, Kodiak, and Big Bear models, but the listed included component is a knuckle rather than a full rebuild kit.

A broad Yamaha application list is the defining advantage of this MOTO1988 rear independent suspension knuckle kit, spanning named Rhino, Grizzly, Kodiak, and Big Bear models. It enables owners of many listed machines to source a knuckle-related replacement, while the package’s spacers, solid bushes, and thrust covers support that focused service task.

The included component is a rear independent suspension knuckle, and the package lists two spacers, four solid bushes, and four thrust covers. Those named pieces give buyers a clearer view of the accompanying hardware for service planning. Fitment covers selected Rhino, Grizzly, Kodiak, and Big Bear models across multiple years, including Grizzly 700 through 2024 and Kodiak 700 from 2016–2024. The extensive range makes exact model and year matching essential; this is not listed as a complete suspension rebuild kit.

Skip it if you need all components for a one-side suspension rebuild; TUSK TK-50-1075 explicitly includes the upper and lower A-arm and knuckle parts.

This is a fit for Yamaha owners seeking the listed knuckle and accompanying spacer, bush, and thrust-cover hardware. Its broad model range still requires careful year and machine matching, and buyers needing a complete one-side rebuild should look elsewhere.

#7

7. Bilstein B12 Land Cruiser Kit

Best for: Land Cruiser 1.75-inch lift.

Why it ranks #7: Designed for a Toyota Land Cruiser with a 1.75-inch lift, but the listing does not identify it as an independent rear suspension rebuild kit.

A specified 1.75-inch lift application sets the Bilstein B12 Special rear suspension kit apart for 2013–2018 Toyota Land Cruiser owners. The product description says the kit alters ride height for a specific requirement, giving buyers a defined lift target instead of a general-purpose rear suspension replacement.

Bilstein identifies this B12 Special kit for the 2013–2018 Toyota Land Cruiser and specifies a 1.75-inch lift, which helps buyers assess whether its ride-height target matches their build. The product description says the suspension kit uses different technologies to reach the required ride height, while the key feature statement frames it around suspension dynamics, quality, and aesthetics. The listing does not name those technologies or provide an installation procedure, so those details cannot guide component-level planning.

Skip it if you need an ATV rear independent suspension rebuild kit; this Bilstein listing is for a lifted Toyota Land Cruiser.

This suits a Toyota Land Cruiser owner seeking the listed 1.75-inch rear lift application for model years 2013–2018. It is a vehicle-specific ride-height kit, not a universal IRS rebuild, and the stated lift target is its key boundary.

#8

8. KUAFU Triangulated 4-Link Kit

Best for: Custom triangulated-link builds.

Why it ranks #8: This alloy-steel triangulated four-link system targets lowered, custom, race, or off-road cars, not ATV independent rear suspension rebuilds.

A triangulated four-link layout paired with a weld-on mount bracket makes this KUAFU kit a fabrication-oriented option for custom rear suspension work. The listing targets lowered cars, custom vehicles, and race or off-road vehicles, with adjustable height and improved stability and handling precision identified as intended outcomes.

The alloy-steel kit combines a triangulated four-link suspension with a triangulated mount bracket, giving fabricators the core layout and mount called out in the package. KUAFU describes use in lowered cars, custom vehicles, and race or off-road applications that require adjustable height. The listing also connects the four-link system and air-suspension control with stability and handling precision, and cites better body control, reduced wheel hop, and reduced body roll. Its weld-on format makes installation a fabrication task.

Skip it if you need a vehicle-specific bolt-on independent rear suspension kit; this is a weld-on triangulated four-link package for custom work.

This suits a fabricator modifying a lowered car or custom race or off-road vehicle who wants a triangulated four-link layout. It is not an ATV IRS replacement, and the weld-on mount calls for a fabrication-capable installation.
