Features

High-strength overlay plate with reduced thickness enhances fatigue resistance, ensuring longevity under stress.
Hardened steel backs on all rod bearings provide superior support for the bearing lining and enhance retention in the housing.
Increased crush improves bearing retention, preventing movement during extreme conditions.
Elimination of flash plating on the back of the bearings improves heat transfer, maximizing grip between bearings and housing.
Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
3/4 grooved main bearings optimize load-carrying surface area and oil flow to conrod bearings, enhancing lubrication.
Tight, consistent wall tolerances help maintain proper clearances for optimal engine performance.
Enlarged ID chamfers accommodate large fillet radius on performance crankshafts, ensuring a perfect fit.
