How to Install Wheels on Snowmobile Skis? | Kit-by-Kit Methods

Adding wheels to a snowmobile’s front end reduces ski wear on hard surfaces and makes loading onto trailers easier. If you’re wondering how to install wheels on snowmobile skis, the process depends on which kit type you’re working with — and getting the orientation right matters more than the tools you use. This guide covers the three main approaches using verified manufacturer procedures, so you know what to expect before you lift the sled.

If you’re comparing kits before buying, our roundup of the best wheels for snowmobile skis covers tested options across all three types.

Which Installation Approach Fits Your Sled?

Wheel kits fall into three categories, and each uses a different mounting strategy. Bogie wheel kits replace or supplement the small wheels inside the track rail and typically use existing mounting points. Rear axle wheel kits swap the stock rear axle hardware for a larger wheel assembly, requiring track adjustment and torque-specific fastener steps. Ski-mounted kits — like the Kimpex Rouski — attach directly to the ski, replacing the original ski bolt with a supplied axle and often requiring a secondary drilled hole. Compatibility depends on your snowmobile brand, ski type, and rail design, so confirming the kit matches your sled is step zero before any tools come out.

One rule is universal regardless of the kit: pay close attention to left and right orientation. Several official instructions state the wheels must be installed on the correct side and positioned directly across from each other on both skis. A wrong-side install is the most common mistake in reviews and kit instructions alike.

Installing Bogie and Rear Axle Wheel Kits

Both bogie and rear axle kits mount to the track rail rather than the ski itself, so the procedure centers on track tension, fastener torque, and cross-alignment.

Bogie wheel kit steps (Polaris Bogie Wheel Kit): Install one set of wheels on the left rail and the other on the right rail. They must sit directly across from each other, with the wheels positioned to the inside and outside of the rail as shown in the kit diagram. This cross-alignment prevents binding and uneven wear during use. The kit diagram is critical — the wheels have a specific inside/outside position on each rail, and reversing them affects track clearance.

Rear axle wheel kit steps (Polaris XCR Rear Axle Wheels Kit): Raise the snowmobile by the running boards using a hoist — do not lift by the rear bumper, as it can compress the rear track shock. Loosen the track adjuster bolt jam nut with a 15 mm wrench, then back out the adjuster bolt until flush. Remove the rear axle hardware, discarding the old axle bolt and washer. Reuse selected spacers and replace bushings and a spacer with the supplied kit parts. Install the new wheels, spacers, and bushings in the stated sequence, then retighten track tension and wheel bolts to the specified torque. The Polaris XCR Rear Axle Wheels Kit instructions provide the exact torque values and fastener order.

After tightening, rotate the track by hand to confirm the wheels spin freely without binding.

Installing a Ski-Mounted Wheel Kit

Ski-mounted kits such as the Kimpex Rouski attach directly to the ski and often require drilling. Start by securing the carbide depth adjuster with wood blocks and a clamp, then remove the ski and its pads. Place the Rouski on the ski — left and right parts differ, so confirm orientation — then reinstall the ski using the axle that replaces the original bolt. The final step is drilling the ski for the second retaining bolt. Use a drill bit sized to match the supplied retaining bolt and deburr the hole after drilling to prevent stress cracks around the fastener. Not all ski-mounted kits require drilling, so check your kit’s instructions before starting.

A recurring issue with this type of kit is installing the left and right assemblies on the wrong sides. Label the parts before removing any hardware to avoid confusion. The Rouski system also requires the carbide depth adjuster to be secured properly — wood blocks and a clamp prevent the ski from shifting during the bolt swap.

FAQs

Do all wheel kits require drilling?

No. Bogie and rear axle wheel kits typically use existing mounting points and need no drilling. Ski-mounted kits like the Kimpex Rouski often require drilling for a secondary retaining bolt. Always check the kit instructions before starting.

Can I install wheel kits on any snowmobile?

Compatibility depends on the snowmobile brand, ski type, spindle and rail design, and whether the kit is for skis, bogie wheels, or rear axle use. A kit designed for one chassis may not fit another. Confirm fitment with the manufacturer before purchasing.

What happens if I install wheels on the wrong side?

Installing wheels on the wrong side is the most common installation mistake. It causes misalignment, uneven wear, and poor tracking. Many kit instructions explicitly warn that assemblies are side-specific and must be positioned directly across from each other on both skis.
