Clevite® offer the most extensive line of performance engine bearings in the market. Their range of performance engine bearings is designed to provide winning results even in the most demanding applications. Their involvement in INDY, NASCAR, ARCA, NHRA and IHRA racing as well as other forms of motorsports have proven Clevite® to be the leaders in engine bearing technology both on the track and off.


Clevite® heavy duty engine bearings includes rod, main, and cam bearings. All but the cam bearings are made with the legendary Clevite® TriMetal™ CL-112 material. Clevite® cam bearings are precision bored to eliminate the need for machining after installation. This exclusive bearing design features a steel backing for support, a cast-copper lead alloy center for strength and durability, nickel dam for chemical stability, and an electroplated white metal babbitt overlay for slipperiness, conformability and embedability. The intermediate cast-copper lead layer creates and interlocked columnar structure capable of withstanding much heavier pulsating loads than any other bearing design.

Clevite® TriMetal™ engine bearings have been tested and given a 12,000 psi rating, the highest in the industry. They are more resistant to corrosion and out-perform traditional bearings by 20 percent or more. That makes Clevite's TriMetal material the strongest currently available in the industry.
