• ACL Race Series bearings are recognized as a premier brand throughout the motorsports world and are standard components in race engines that have set records and won championships
• Hardened steel backs on all rod bearings improve support of the bearing lining and assist with bearing retention in the housing
• Elimination of flash plating on the back of the bearings improves heat transfer and maximizes grip between the bearings and housing
• Tight consistent wall tolerances help maintain consistent clearances
• Unique combination of design, metallurgy and engineering provides endurance and capability to perform where others cannot

This .020" oversize bearing set is specifically designed for crankshafts that have been ground undersize to restore proper clearances during engine rebuilds. ACL bearings are used for tuning and engine upgrades where you want better quality with higher bearing capacity than normal standard bearings.
