Wiseco Crankshaft Bottom Kit with Bearings and Gaskets WPC142. Precision-trued to OEM specifications. Connecting rods are double-forged for superior dimensional consistency. Shot-peening eliminates residual stresses and smoothly blends rod forging surfaces. Corrosion-resistant surface treatment. Top and bottom end rod bores are case hardened to 58-62 RC to optimize the bearing running surface. Crank pin bearing radial running clearance is optimized for maximum performance. Precision honing ensures an ultra-round bearing surface. Precision-engineered oiling slots maximize rod strength and bearing life. Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing distortion of the top end due to thermal transfer from the piston. Silver-coated bronze phosphor thrust washers with a dimpled design increase oil retention and reduce friction between the rod and washer interface. Crank pin bearings are manufactured with the highest-quality hot-rolled steel and case hardened to 58-62 RC.
