ACL Race main bearings are trimetal engine bearings designed for higher RPM conditions. Their combination of design, metallurgy and engineering provides improved properties for high-performance engines.
The construction is designed for secure retention in the housing, effective heat transfer and the formation of hydrodynamic oil films. The set contains ACL Race Series main bearings.
- High-strength overlay plate with reduced thickness for improved fatigue properties
- Increased crush for improved bearing retention in the housing
- Elimination of flash plating on the back for improved heat transfer and increased grip in the housing
- Increased eccentricity to compensate for bore distortion at high RPM
- 3/4-grooved main bearings to optimize bearing load-carrying surface area and oil flow
- Tight, consistent wall tolerances to help maintain consistent clearances

Sizes
STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
