ACL 3BS8389A-STD Balance Shaft Bearing

The ACL 3BS8389A-STD Balance Shaft Bearing is engineered for those who demand reliability and performance from their engine components. Utilizing advanced metallurgy and precision engineering, this bearing is designed to endure the rigors of high RPM conditions, making it an ideal choice for both street and track applications.

Key Features

  • High Strength Overlay Plate: The reduced thickness enhances fatigue properties, ensuring durability under extreme conditions.
  • Hardened Steel Backs: All rod bearings feature hardened steel backs to improve support for the bearing lining and enhance retention in the housing.
  • Increased Crush: This design element improves bearing retention, ensuring a secure fit during operation.
  • Optimized Heat Transfer: The elimination of flash plating on the back of the bearings enhances heat dissipation and maximizes grip between the bearing and housing.
  • Increased Eccentricity: This feature compensates for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films for better lubrication.
  • 3/4 Grooved Main Bearings: Designed to optimize load-carrying surface area and oil flow to conrod bearings, enhancing overall engine efficiency.
  • Tight Wall Tolerances: Consistent wall tolerances help maintain precise clearances, crucial for high-performance applications.
