Product details:

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings. Designed to withstand higher RPM conditions - Features: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 bearings and 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.
