Description

A worn or noisy bottom end can create major issues for your Polaris Switchback 600 snowmobile. You may hear bearing noise, feel extra vibration or notice unstable idle. Since these symptoms often point to crankshaft wear or sealing problems, rebuilding the lower end is one of the best ways to restore dependable performance. This Complete Bottom End Rebuild Kit gives you the core components needed to strengthen the foundation of your engine.

The kit includes a direct-replacement crankshaft, a full gasket set with oil seals and the correct water pump mechanical seal. These components work together to restore smooth rotation, prevent internal leaks and prepare the engine for many more miles of winter use. Riders planning a complete refresh often pair this with our Switchback 600 top-end kit to complete the rebuild.

If you have questions about fitment or installation, our FAQ page is a helpful resource. Every parts kit includes our 1-year, no-questions-asked warranty. You can review the full details inside our warranty policy. For new customers, the Help Center explains shipping and rebuild preparation.
