ACL's Race bearings, or H-series, are recognized as a premier brand throughout the motorsports industry. H-series bearings feature an increased level of eccentricity which compensates for distortion at high RPMs, and bearing retention is improved with a higher crush. The edge of the bearings have a large chamfer for better crankshaft fillet clearence, and the elimination of flash plating on the back creates better seating and improves heat transfer. Superior engeering, and bearing design along with a half-century of manufacturing experence give ACL Race Series bearings the endurance and ability to perform where others can't.
