ACL bearings are used for tuning and engine upgrades where you want better quality with higher bearing capacity than normal standard bearings. Improvements of material, dynamic thickness, heat conduction, oil grooves and oil distribution are some of the points that make ACL one of the leading bearing manufacturers.
