PRODUCT DESCRIPTION
Product details
The unique combination of design, metallurgy, and engineering come together to deliver what drivers expect from high performance Tri-Metal engine bearings.
Engineered to withstand high RPM conditions, ACL Race Series Engine Bearings are available for many popular 4, 6, and 8 cylinder applications and feature the following:
High strength overlay plate with reduced thickness for improved fatigue resistance.
Hardened steel backing on all conrod bearings for improved support of the bearing lining and to 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 and to maximize the grip between the bearing 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 for optimized load carrying capacity and oil flow to the conrod bearings.
Tight and consistent wall tolerances to maintain consistent clearances. Enlarged ID chamfers on bearing edges, where required, to accommodate large fillet radii on high performance crankshafts.
