Description

The Cosworth Main Bearing Set is a performance-engineered component designed for Subaru WRX/STI EJ25 and EJ20 engines. These tri-metal bearings generate less heat and reduce friction for high-performance applications. Features include a high-strength overlay plate, hardened steel backing, increased crush, and 3/4 grooving for optimal oil supply, along with tight, consistent wall tolerances.
