The ACL 5M1957H-.25 Main Bearing Set is engineered for those who demand reliability and performance in their engines. Designed specifically for Honda H22A4 and Acura D16A1 applications, this bearing set features advanced metallurgy and precision engineering to meet the rigorous demands of high RPM conditions.

Key Features

  • Trimetal Construction: The bearings utilize a unique tri-metal design that combines a high-strength overlay plate with hardened steel backs, enhancing durability and performance.
