ACL Race Series Engine Bearings - Honda

The unique combination of design, metallurgy and engineering delivers what drivers expect from high-performance Trimetal engine bearings.

Designed to withstand higher engine speeds, ACL Race Series engine bearings are available for many popular 4-, 6- and 8-cylinder applications, and feature:

High-strength cover plate with reduced thickness to improve fatigue properties

Hardened steel backs on all connecting rod bearings to improve bearing liner support and help retain the bearing in the housing.

Increased crush for better bearing retention

Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and maximize adhesion between the bearings and their housing.

Increased eccentricity to compensate for high-speed bore distortion and promote hydrodynamic oil film formation.

3/4 grooved main bearings to optimize bearing load surface and oil flow to connecting rod bearings.

Tight, consistent wall tolerances to help you maintain constant clearances.

Enlarged identification chamfers on bearing edges where necessary to accommodate large fillet radii on high-performance crankshafts.
