Hot Rods 96-97 Polaris SL 700 700cc Wrist Pin Bearing

Made from hot-rolled ASTM 4115 steel, this wrist pin bearing is case-hardened to a hardness of 58-62 Rc. This level of hardness helps it stand up to the constant motion and friction it experiences in the engine. It's a well-built component designed to keep your engine running smoothly.

This bearing is a crucial part of the connection between the piston and the connecting rod. Its job is to allow the piston to rock back and forth smoothly as it moves up and down in the cylinder, while also handling the forces from the connecting rod. Having a strong, properly hardened bearing here is key to preventing premature engine wear.
