Carrying on a tradition of durability and dependability, Clevite Bi-Metal (aluminum) engine bearings feature 100% lead-free aluminum silicon. Engineered with 60% more silicon than comparable competitive replacements, they provide better conditioning of journal surfaces. This results in greater seizure and wear resistance.
