ACL 5M1957A-STD Main Bearing Set

The ACL 5M1957A-STD Main Bearing Set is engineered for high-performance applications, providing the durability and reliability needed for demanding driving conditions. These tri-metal bearings are designed specifically for the Honda D-series engines, ensuring optimal fitment and performance.

Key Features

  • High strength overlay plate with reduced thickness enhances fatigue resistance, making these bearings suitable for higher RPM applications.
