ACL

ACL is a leading manufacturer of high-performance engine bearings, trusted by engine builders worldwide for everything from daily-driven street cars to full-race competition engines. The ACL collection features precision-engineered main bearings, rod bearings, thrust washers, and related components designed to withstand extreme loads and high RPM operation.

Key features of ACL bearings include:

  • Tri-metal construction with a copper-lead alloy intermediate layer for superior fatigue strength and embedability
  • Race Series options with extra attention to eccentricity and crush height for high-revving applications
  • Proprietary coatings and surface treatments to reduce friction and protect during startup
  • Precise sizing and wall thickness consistency for reliable oil clearance

When selecting ACL bearings, match the bearing type and size to your specific engine build. Race Series bearings are ideal for naturally aspirated or forced induction engines making significant power, while standard ACL bearings provide excellent durability for spirited street use. All ACL products are manufactured to strict tolerances using high-grade materials, ensuring consistent performance and longevity.
