Shopper Award

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 coated H-Series rod bearings were developed primarily for NASCAR racing, but are also well suited to other types of competition engines. They're especially good for engines that run at medium-to-high revs. They have hardened-steel backings with thin overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings feature Clevite's exclusive TriArmor coating, the industry's only moly/graphite treatment. The sophisticated blend, in a low-friction PTFE polymer base, offers extraordinary protection and lubricity. They also have enlarged chamfers at the sides for greater crank-fillet clearance and are made without flash plating for better seating. The Clevite coated H-Series rod bearings are available with various under-sizes, including 0.001 in. of clearance for polished journals.
