Corvette LS3/LS7 Clevite H-Series Main Bearings, Set of 5

LSx Main Bearings, H Series, 1/2 Groove, Standard Size, Tri Metal, Chevy, Small Block, Set of 5

Clevite H-Series main bearings were developed primarily for NASCAR racing, but are well suited to other types of competition engines. They're especially good for engines that run at medium-to-high revs. They have steel backings with carefully selected overlays and a high crush factor, plus a medium level of eccentricity. H-Series bearings have enlarged chamfers at the sides for greater crank-fillet clearance, and are made without flash plating for better seating. They're also available with either 180-degree or 360-degree oil grooves, as well as an extra 0.001 in. of clearance.
