Product Description
ACL, Automotive Components Limited, is a premier engine bearing manufacturer based in Australia. Race Series performance bearings are products of more than a half-century of ACL research, design, metallurgy and manufacturing experience. They are used extensively by racers and engine builders in the U.S. and around the world. ACL’s experience includes designing and manufacturing OE bearings for GM, Ford and Toyota. Race Series bearings are available for numerous performance engines and in many different sizes.


ACL High Performance Bearing Features:
-Designed to withstand higher RPM conditions.
-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 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.

Available Sizes:
Standard, .025, .25, .50, & Standard Size +.001 Extra Oil Clearance

The ACL Extra Oil Clearance Main Bearings are highly recommended for anyone using Forged Rod's. The reason is because Forged Metals expand much more under high temperatures, & require a looser Beraing to provide proper oiling.

We recommend consulting with your Engine Builder before ordering your Bearing Set.
