The unique combination of design, metallurgy  and engineering come together to deliver what drivers expect from high performance Tri-metal engine bearings.

Designed to withstand higher RPM conditions, ACL Race Series Engine Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature: 

- High strength overlay plate with reduced thickness for improved fatigue properties

- Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. 

- Increased crush for improved bearing retention

-Elimination of flash plating on the back of the bearings to improve heat transfer through the bearing sand to maximize the grip between the bearings and its housing. 

-Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.

- 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the con-rod bearings. 

- Tight consistent wall tolerances to help you maintain consistent clearances.

- Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
