If you're looking to push your engine to its limits, the ACL Race Series Engine Bearings (part number 4B7700H-STD) are designed specifically for high-performance applications. These trimetal bearings are engineered to handle the rigors of high RPMs, making them a perfect choice for enthusiasts who demand reliability and performance from their engines.

Fitment

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, allowing for better performance under stress.
  • Hardened steel backs on all rod bearings improve support and retention in the housing, ensuring they stay put when you need them most.
  • Increased crush enhances bearing retention, providing a more secure fit within the engine.
  • Elimination of flash plating on the back of the bearings promotes better heat transfer and maximizes grip between the bearings and housing.
  • Increased eccentricity helps compensate for bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the conrod bearings for improved lubrication.
