Best Aftermarket Snowmobile Suspension for Different Sleds

#1 · Best Overall

1. Gonetre Suspension Lift Kit

Best for: Kitty Cat deep-snow lift kit.

Why it ranks #1: This lift and widening kit specifies 3-inch rear lift and 2.5-inch front lift and widening, with fit listed for Arctic Cat Kitty Cat models from 1972 to 1999.

A 3-inch rear lift paired with a 2.5-inch front lift and widening gives this Gonetre kit a specific deep-snow setup for Arctic Cat Kitty Cat sleds. The raised and widened stance is intended to improve clearance and stability when navigating challenging terrain.

The kit raises the rear wheels by 3 inches and raises and widens the front wheels by 2.5 inches, changes that the listing connects to improved clearance and deep-snow travel. Gonetre specifies compatibility with Arctic Cat Kitty Cat models from 1972 through 1999, so the application is narrow rather than broadly universal. Stainless steel components are described as wear-resistant and durable for varied terrain. The listing does not specify installation steps or enumerate included components, so buyers should account for that limited setup information.

Skip it if you own a snowmobile other than the listed Arctic Cat Kitty Cat 1972–1999 application.

Choose this for a Kitty Cat owner seeking the listed lift and widening changes for deep-snow travel. Its stated application is restricted to Arctic Cat models from 1972 through 1999, so it is not a general-purpose lift kit.

#2 · Best Gas Shock

2. Kimpex Rear Arm Shock

• Weight: 1347.17 g

Best for: Arctic Cat gas-shock replacement.

Why it ranks #2: The listing identifies a gas shock for Arctic Cat snowmobiles and specifies rear suspension front-arm placement, with 12-inch extended eyelet spacing.

A gas shock specified for the rear suspension front arm gives this Kimpex replacement a defined job on compatible Arctic Cat snowmobiles. Its listed extended eyelet center-to-center length is 12 inches, making the measurements and application more useful to a replacement buyer than a generic shock description.

Kimpex identifies the shock as a direct OEM replacement for Arctic Cat snowmobiles and specifies its rear suspension front-arm position. The 12-inch extended eyelet spacing and 8 3/8-inch compressed spacing give a buyer concrete dimensions to compare with the existing component before planning a replacement. The 5/8-inch top and 3/8-inch bottom eyelet diameters add further fit details. It is a gas shock, but the supplied information does not identify damping adjustments or installation steps.

Skip it if you need a listed model-by-model fit range; the supplied compatibility information names Arctic Cat only.

This suits an Arctic Cat snowmobile owner replacing a rear suspension front-arm shock who can use the listed dimensions to check the existing part. Treat the limited compatibility description as a fit boundary; no particular model range is supplied.

#3 · Heavy-Duty Kit

3. Bear Flag Heavy Duty Shock Kit

Best for: Arctic rough-terrain shock kit.

Why it ranks #3: This is explicitly described as a heavy-duty shock kit for Arctic snowmobiles, but the listing gives no clear model fitment, so verify compatibility before buying.

A heavy-duty shock kit identified for Arctic snowmobiles is the central feature here, with the listing linking its construction to durability on rough terrain. It targets owners seeking a replacement shock kit for demanding snowmobile use, though the product information leaves fit details notably limited.

The listing describes the 4639-137 kit as heavy duty and says it is engineered to withstand the rigors of snowmobiling. That emphasis supports considering it for rough-terrain use, where the supplied description also claims a smoother ride and better handling for an Arctic snowmobile. However, no dimensions, included-component breakdown, or specific compatible model range appear in the provided facts. Buyers can assess its stated purpose, but the listing offers little detail for checking application or planning installation.

Skip it if you need dimensions or a model-by-model compatibility list to verify the shock kit’s application before buying.

Consider it if you own an Arctic snowmobile and want the listed heavy-duty replacement kit for rough-terrain use. Its ride and handling benefits are claims in the listing, while model fit and component details remain unspecified.

#4 · Front Conversion Kit

4. Ski-Doo RAS X Upgrade Kit

• Weight: 15 lb

Best for: RAS 3 to RAS X conversion.

Why it ranks #4: The kit includes new spindles, A-arms, and hardware for converting RAS 3 to RAS X on specified REV Gen4 models, but it is factory original equipment.

A complete set of new spindles, A-arms, and necessary hardware makes this RAS X kit a defined conversion from RAS 3 front suspension. Its wider ski stance is intended to support sure-footed cornering and improved bump performance on specified REV Gen4 touring and trail models.

The kit updates a sled from RAS 3 to RAS X and includes new spindles, A-arms, and the necessary hardware, so buyers get the listed core conversion components together. Ski-Doo connects the wider ski stance to sure-footed cornering and improved bump performance, offering a clear handling purpose. Compatibility is specified for REV Gen4 MXZ, Renegade, and Grand Touring models with RAS 3 front suspension. Pilot X ski compatibility is also listed, while shocks are not included.

Skip it if you need shocks included or your REV Gen4 sled lacks the listed RAS 3 front suspension.

Choose this for a compatible REV Gen4 MXZ, Renegade, or Grand Touring owner converting RAS 3 to RAS X. The kit’s wider stance and included hardware support that upgrade, but shocks are not part of the package.

#5

5. Ski-Doo REV Front Suspension Kit

• Weight: 26 lb

Best for: REV-XM adjustable front stance.

Why it ranks #5: This front kit includes HPG shocks and adjustable ski stance from 35.7 to 37.4 inches for REV-XM, XS, and XP, but it is factory original equipment.

An adjustable ski stance from 35.7 to 37.4 inches sets this Ski-Doo front suspension kit apart for REV-XM, XS, and XP owners. The kit also targets an update to the REV-XM Summit X with T3 package, with stated handling benefits from S-36 and RAS 2 features.

The kit includes HPG shocks and an adjustable ski stance, giving buyers both specified shock hardware and a way to choose between 35.7- and 37.4-inch stance settings. Ski-Doo says the setup delivers S-36 agility alongside RAS 2 benefits and better straight-line tracking over big bumps. Its listed REV-XM, XS, and XP compatibility narrows the intended application, while the Summit X with T3 update purpose adds context. It is genuine factory equipment, not aftermarket.

Skip it if you need an aftermarket kit or your sled is outside the listed REV-XM, XS, and XP platforms.

This fits a Ski-Doo REV-XM, XS, or XP owner seeking adjustable ski stance, HPG shocks, and the stated handling updates. It is a factory-original kit, and the listed platform range defines its fit boundary.

#6

6. Ski-Doo T-Motion Stiffener

• Weight: 2 lb

Best for: Freeride rail-strength reinforcement.

Why it ranks #6: Its cast-aluminum stiffener is listed for 146-inch-and-up REV Gen4, XM, and XP models with tMotion or cMotion rear suspension, but it is factory original equipment.

Lightweight cast aluminum construction gives this Ski-Doo T-Motion stiffener a focused role: adding strength for hard landings while replacing the stock stiffener on compatible sleds. Its stated fit covers REV Gen4, XM, and XP platforms at 146 inches and up with tMotion or cMotion rear suspension.

The cast aluminum construction keeps the listed component lightweight while its stated purpose is to increase strength for hard landings. Ski-Doo says it can replace the stock stiffener on a Freeride, making it a targeted reinforcement rather than a complete suspension conversion. Compatibility is specifically limited to REV Gen4, XM, and XP sleds measuring 146 inches and up with tMotion or cMotion rear suspensions. That defined fit helps narrow the intended application, but this is factory-original equipment, not aftermarket.

Skip it if you want a complete suspension kit or your sled is outside the listed 146-inch-and-up platforms.

This is for a compatible Ski-Doo Freeride owner seeking a stock-stiffener replacement or added rail strength for hard landings. Check the listed platform, length, and rear-suspension requirements; it is a factory part, not aftermarket.

#7

7. Polaris Rear Track Fox Shock

Best for: Polaris OEM rear-track shock.

Why it ranks #7: This genuine Polaris OEM rear track shock is designed to Polaris specifications, but the supplied listing does not identify compatible snowmobile models.

A genuine Polaris Fox rear-track shock engineered to Polaris OEM specifications is the defining feature of this replacement. The brand states that the specifications support proper fit and function, while its snowmobile-specific designation gives Polaris owners a clear starting point for a rear-track shock replacement.

Polaris identifies this as a rear-track Fox shock and says it is engineered to OEM specifications for proper fit and function. That makes the part’s stated position and manufacturer-specific design relevant to owners replacing a Polaris rear-track shock. Its metal construction is also specified, and Polaris describes the part as made to its standards for reliable operation and durability. The supplied information does not give a compatible model list or shock dimensions, so it cannot establish fit for a particular sled on its own.

Skip it if you need model-level fit information or dimensions; the listing identifies Polaris snowmobiles but not specific models.

This suits a Polaris owner looking for a genuine OEM-spec rear-track Fox shock. Use the listing’s position and brand information as a starting point, not a complete fit check, since it supplies no specific model range or dimensions.

#8

8. Ski-Doo RAS RX Front Suspension

• Weight: 7 lb

Best for: Ski-Doo cornering upgrade.

Why it ranks #8: The front suspension describes taller ski legs and revised geometry, but it is explicitly a factory-original, non-current Ski-Doo part rather than aftermarket.

A taller ski leg and geometry inspired by Ski-Doo’s RAS-RS distinguish the RAS RX front suspension, with the stated aim of improving cornering stability and steering precision. It gives Ski-Doo riders seeking more controlled carving a specific factory suspension option, rather than a universal replacement part.

The taller ski leg is paired with revised geometry, a combination Ski-Doo says enhances cornering stability and steering precision. Those traits matter to riders prioritizing controlled turns and confident line changes across terrain. The listing identifies this as a genuine, factory-original Ski-Doo part, which makes it an OEM replacement or upgrade option within the brand’s parts ecosystem. However, no model compatibility list or installation details are supplied, so the listing alone does not establish which sleds accept it.

Skip it if you need a confirmed fit for a particular sled; the listing supplies no compatibility list or model range.

Choose this for a Ski-Doo owner seeking the stated cornering and steering changes from a genuine RAS RX front suspension. It is factory-original equipment, not aftermarket, and the supplied listing does not specify compatible sled models.
