Description

Rod bearing clearances directly impact oil delivery, heat dissipation, and bearing longevity under sustained high RPM operation. The CB-663HXN H-Series bearing delivers the extra oil clearance needed to maintain film strength in demanding small block Chevy applications, reducing wear and extending engine life. Whether you’re rebuilding a race engine or upgrading a street performance build, this bearing provides the reliability that separates a solid build from one that fails on the dyno.
