Why Choose the Polaris XPEDITION Crankshaft Bearing Kit?

Crankshaft bearings play a critical role in supporting the rotating assembly and maintaining proper oil clearance throughout the engine. As bearings wear, they can reduce oil pressure, increase friction, and lead to expensive engine damage. This Polaris XPEDITION Crankshaft Bearing Kit is designed for 2024-2026 NorthStar ADV and XP models equipped with the ProStar 1000 engine.

Replacing the crankshaft bearings during a rebuild helps protect your crankshaft and creates a dependable foundation for the rest of the engine.
