The majority of Clevite performance engine bearings utilize a superior TriMetala" design first developed by Clevite 50 years ago and perfected over time. This design incorporates the strength of a copper-lead alloy layer on a precision steel back and finally, a precision electroplated white metal "babbitt" surface layer. TriMetal is an ideal design, producing a degree of conformability, embedability, slipperiness and fatigue resistance, not found in many original equipment and competitive bi-metal bearings. The exclusive Clevite TriArmor engine bearings feature the industry's only engine moly/graphite treatment. This sophisticated blend, in a low friction PTFE polymer base, offers extraordinary protection and lubricity. Enhanced wear characteristics increase bearing life in race engines and high performance street engines. Now, high performance engine builders can enjoy the strength and durability of the legendary Clevite TriMetal bearing construction coupled with the latest in coating technology - right out of the box. It's no wonder that Clevite is used more often than any other bearings in cars worldwide and in most race cars. In addition, Clevite has been in most winning engines at Indianapolis and NASCAR.
