Description
A properly sized main bearing set is critical to engine longevity and reliability—it directly impacts oil flow, reduces friction, and prevents catastrophic bearing failure under load. The MS-590P-20 is engineered for Small Block Ford engines requiring 0.020″ undersize clearances, making it essential if you’re rebuilding or replacing worn bearings.
