One often overlooked part when building an engine is the bearings. Getting a quality set of bearings can directly determine the longevity of your engine.
 
ACL Race Series Performance Engine Bearings
 
The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Tri-metal engine bearings. 
 
Designed to withstand higher RPM conditions
 
Features:
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 bearings and 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.
