ACL Bearings 6B610A-20 Performance Connecting Rod Bearing Set Oversize - 020

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, delivering championship-winning reliability for high-performance and racing applications. The 6B610A-20 connecting rod bearing set features a .020" oversize dimension designed for use with reground crankshafts.

Advanced Tri-Metal Construction:

• Multi-alloy bearing featuring lead-tin-copper overlay, nickel barrier, copper-lead-tin lining, and SAE1010 high tensile bearing steel support liner
• Hardened steel backs on all rod bearings to improve support of the bearing lining and assist with bearing retention in the housing
• Elimination of flash plating on the back of bearings to improve heat transfer and maximize grip between bearings and housing
• High strength overlay plate with reduced thickness for improved fatigue properties

Performance Features:

• Increased eccentricity to compensate for bore distortion at high RPM and assist in formation of hydrodynamic oil films
• Tight consistent wall tolerances to help maintain consistent clearances
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts
• Superior heat dissipation through optimized thermal transfer design

The unique combination of design, metallurgy and engineering provides Race Series performance bearings with the endurance and capability to perform where others cannot. These bearings are engineered specifically for high-RPM racing conditions and performance engine builds requiring oversized bearings for crankshaft regrinding applications.
