About this part

Product Details

S&S Cycle is well-known for making strong engine components for Harley-Davidson motorcycles. This right main bearing outer race is a good example of their work, built to keep your Big Twin motor running smoothly. It's made from hardened steel, which means it's built to handle the stresses inside your engine. You'll need one of these for your 1936-1999 Big Twin or S&S KN, P, SH, and V-Series motors.

When you're rebuilding the bottom end of your engine, getting the right bearings is crucial. This outer race is designed to fit precisely and provide a solid surface for the bearing to spin on. Because it's made of hardened steel, it resists wear and helps ensure a long service life for your engine's rotating assembly. This part is sold individually, so make sure you order the correct quantity for your build.
