Description

Main bearing wear is one of the most common causes of catastrophic engine failure, especially under sustained high-RPM or forced-induction loads. The MS-1110H-1 delivers precision-engineered bearing surfaces with tight tolerances to maintain proper oil film strength and reduce parasitic friction losses. If you’re rebuilding a Small Block Chevy for serious performance driving, this complete bearing set ensures your bottom end can handle the power you’re putting through it.

The 0.001-inch undersize specification provides exact fitment on H-Series engine cranks, eliminating the guesswork during assembly and guaranteeing consistent bearing clearances across all journals. This comprehensive kit includes everything needed for a complete main bearing installation, so you won’t be caught short mid-rebuild.
