ACL Race main bearings are high-performance trimetal engine bearings designed for higher RPM conditions. Their design, metallurgy and engineering support consistent engine operation under increased loads.
The construction features increased eccentricity to compensate for bore distortion at high RPM and assist in forming hydrodynamic oil films. The set includes 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 grip in the housing
- 3/4-grooved main bearings to optimize bearing load-carrying surface area and oil flow to the conrod bearings
- 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.
