ACL 6B1569HX-STD Rod Bearings for BMW S54B32

The ACL 6B1569HX-STD rod bearings are engineered for high-performance applications, specifically tailored for the BMW S54B32 engine. These tri-metal bearings are designed to handle the rigors of high RPM conditions, ensuring durability and reliability under extreme stress.

Key Features

  • High Strength Overlay: The overlay plate features a reduced thickness to enhance fatigue resistance, making it ideal for performance applications.
  • Hardened Steel Backs: Each rod bearing is equipped with hardened steel backs, providing superior support for the bearing lining and enhancing retention within the housing.
  • Increased Crush: Optimized crush design improves bearing retention, ensuring a secure fit under dynamic loads.
  • Improved Heat Transfer: The elimination of flash plating on the back of the bearings facilitates better heat dissipation, maximizing grip between the bearings and their housing.
  • Enhanced Eccentricity: Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films for improved lubrication.
  • 3/4 Grooved Main Bearings: This design optimizes the load-carrying surface area and enhances oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Consistent wall tolerances help maintain precise clearances, crucial for performance applications.
  • Enlarged ID Chamfers: Chamfered edges accommodate large fillet radii on performance crankshafts, ensuring a proper fit.
