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 bearings and 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 conrod 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.
