Look inside most winning Indy cars and NASCAR vehicles and you'll find Clevite engine bearings. Since the development of the first precision insert-type bearing in 1929, Clevite bearings set the pace for engineering quality, and today they exceed industry standards for strength and durability. Most Clevite performance bearings use a special TriMetal design, first developed 50 years ago and perfected over time. A copper-lead alloy is added to a steel back, which is then electroplated with a white metal surface layer which produces an ideal degree of conformability, embedability, slipperiness, and fatigue resistance. Summit Racing also has other Clevite engine components like pistons, rings, and cam lifters, all manufactured to the same high.

Clevite P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are constructed of tri-metal cast copper lead. They have a steel back for support, a cast copper lead lining to withstand the loads of engine operation, and an electroplated babbit overlay on the running surface to provide searing surface qualities. In addition, the oil grooves on most applications extend all the way around both halves for better oiling.

Clevite P-Series main bearings are an ideal design, producing a degree of conformability, embedability, slipperiness, and fatigue resistance, not found in original equipment and competitive bimetal bearings.
