Important note on appearance
ACL Race Series performance bearings have a darker surface finish that can appear black, brown or blue. This is simply the electroplated overlay that contains copper and naturally tarnishes. It has negligible thickness and does not affect operation. Unlike regular aftermarket bearings with a silvery tin flash, ACL Race bearings are intentionally supplied without this cosmetic layer to avoid any risk of plate movement under high heat and load. The result is better shell to housing contact and consistent bearing performance.
