ACL connecting rod bearings S54

HIGH STRENGTH OVERLAY PLATE with reduced thickness for improved fatigue properties
HARD STEEL RUGS on all rod bearings to improve bearing liner support and help retain bearings in the housing.
HIGH CRUSH for improved bearing retention
ELIMINATION OF FLASHPLATING on the back of the bearings to improve heat transfer through the bearings and maximize grip between the bearings and housing.
HIGH EXCENTRICITY to compensate for bore deformation at high speeds and to assist in the formation of hydrodynamic oil films.
3/4 GROUNDED MAIN BEARINGS to optimize bearing surface area and oil flow to connecting rod bearings.
STRONG CONSISTENT WALL TOLERANTS to help you maintain consistent clearances.
LARGE ID FACING on bearing edges where necessary to allow large rounding radius on high performance crankshafts.
