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