In the ACL Race Series, the unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings.

Designed to withstand higher RPM conditions, ACL Race Series Engine Bearings are extremely well respected amongst Subaru Engine builders.

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 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 maximise the grip between bearings and its housing

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

Tight consistant wall toleranced to help maintain consistant clearances

Enlarged ID chamfers on bearing edges where required to accomodate large fillet radius on performance crankshafts
