Inner Cam Bearings / Evo, Twin Cam, Sportster & M8

Heavy-duty full-complement inner cam bearings, covering four engine eras.

Inner cam bearings are a routine replacement any time the camchest is open, and running a worn one back in is a false economy. These are full-complement bearings manufactured by Koyo Torrington, built to take the higher loads and demands of a performance engine.

Choose the variant that matches your motor. The count differs between engines, so read the unit in the option before you order.
