Restore smooth engine operation and support long-term reliability with these replacement main bearings for applicable Polaris 700 and 800 engines. Designed for use during bottom-end repairs and engine rebuilds, these bearings help maintain proper crankshaft support and engine performance.

Why Replace Main Bearings?

Main bearings support the crankshaft and help keep rotating components aligned. Over time, heat, mileage, and engine load can create wear that leads to vibration, excessive play, noise, or reduced engine life.

Therefore, replacing main bearings during a rebuild helps improve reliability and protects surrounding bottom-end components.

Completing a Larger Rebuild?

This product pairs well with crankshaft service, seal replacement, gasket kits, and engine refresh projects. In addition, if you’re servicing crankshaft bearings or planning a deeper bottom-end rebuild, review our Polaris Crankshaft Bearing Mapping Guide to help identify proper bearing selection.

If your engine needs additional components, review our Engine Rebuild Kit Guide for available rebuild paths and rebuild levels.
