Description

* High strength overlay plate with reduced thickness for improved fatigue properties * Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing. * Increased crush for improved bearing retention * Elimination of flash plating on the back of the bearings to improve heat transfer through the bearing sand to maximize the grip between the bearings and its housing. * Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films. * 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings. * Tight consistent wall tolerances to help you maintain consistent clearances. * Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
