The ACL 4B1912HX-STD rod bearings are engineered for high-performance applications, specifically designed for Honda engines including the F20C, F22C, and the 1997-2001 H22A4. These bearings feature a unique tri-metal construction that enhances durability and performance under high RPM conditions.

Key Features

  • High strength overlay plate with reduced thickness improves fatigue resistance, making these bearings ideal for racing and high-stress scenarios.
  • Hardened steel backs on all rod bearings enhance support for the bearing lining and ensure reliable retention within the housing.
  • Increased crush design improves bearing retention, ensuring they stay securely in place during operation.
  • Elimination of flash plating on the back optimizes heat transfer, maximizing grip between the bearing and its housing.
  • Enhanced eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films for better lubrication.
  • 3/4 grooved main bearings optimize the load-carrying surface area and improve oil flow to the connecting rod bearings.
