Description
Main bearing wear is one of the most critical failure points in any high-performance engine build, and choosing the right bearing set directly impacts reliability and longevity under sustained load. The Calico Coated MS909H20 delivers the precision tolerances and durability you need when rebuilding or refreshing your small block Chevy, with factory-grade engineering that meets the demands of both street and racing applications. The Calico coating reduces friction and improves oil film strength, giving you confidence that your bottom end will hold up through extended heat cycles and high RPM runs.
