Description

A worn top end can cause your Polaris LX 600 snowmobile to lose power, hesitate off idle and run less efficiently in cold conditions. Since these issues often come from tired pistons or worn bearings, refreshing the upper end is one of the most effective ways to bring performance back. This Top End Rebuild Kit gives you the core components needed to restore smooth operation.

Inside the kit are matched piston kits complete with rings, wrist pins and circlips. It also includes new needle cage bearings and a full top-end gasket kit. Combined, these parts help rebuild compression, reduce internal wear and improve throttle response. Riders comparing rebuild options often review our LX 600 full engine kit for a deeper restoration.

If you need help determining fitment or installation steps, visit our FAQ resource. Every parts kit includes our 1-year, no-questions-asked warranty for added peace of mind. Full coverage information is available inside our warranty policy. New customers can also take advantage of our Help Center for shipping guidance and rebuild preparation.
