ACL 5M2964H-.025 High Performance Main Bearing Set

The ACL 5M2964H-.025 is engineered specifically for high-performance applications in the Nissan SR20DE and SR20DET engines. This main bearing set is crafted with a tri-metal design that combines advanced metallurgy and precision engineering, making it a reliable choice for those pushing their engines to higher RPMs.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, ensuring durability under extreme conditions.
  • Hardened steel backs on all bearings provide superior support for the bearing lining and improve retention within the housing.
  • Increased crush for enhanced bearing retention, critical for maintaining stability during operation.
  • Elimination of flash plating on the back of the bearings improves heat transfer and maximizes grip between the bearings and housing.
  • Enhanced eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved design optimizes load-carrying surface area and oil flow to the connecting rod bearings.
