ACL Race Main Bearings (EJ20, EJ25)

These are ACL's Race Bearings for the Subaru EJ20/EJ25

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from the ACL Race Series high-performance

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
