Product Description

The ACL 5M2964H-.25 Race Main Bearing Set is engineered for high-performance applications, specifically designed for Nissan SR20DE and SR20DET engines. These bearings are 0.25mm oversized, catering to engines that have undergone machining to restore journal dimensions.

Constructed with a trimetal design, the bearings feature a copper-lead overlay that enhances durability and resistance to wear. The hardened steel backs improve bearing retention, making them suitable for both street and track applications. The increased eccentricity compensates for bore distortion at high RPM, ensuring optimal oil film formation.

These bearings are ideal for enthusiasts and racers seeking to upgrade their engine internals for improved performance and durability. Whether you're restoring a classic Nissan or building a high-performance engine, the ACL 5M2964H-.25 bearing set delivers the reliability and strength needed to withstand the demands of racing and high-performance driving.
