Wiseco Crankshaft Assembly with Bearings and Gaskets. Precision-trued to OEM specifications. Connecting rods are double-forged to maintain superior dimensional consistency through improved grain flow. Shot-peening eliminates residual stresses and smoothly blends the rod forging surfaces. Features corrosion-resistant surface treatment. Top and bottom end rod bores are case hardened to 58-62 RC to optimize bearing running surface. Crank pin bearing radial running clearance is optimized to ensure 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 top end due to thermal transfer from the piston. Silver-coated bronze phosphor thrust washers with dimpled design increase oil retention and reduce friction between rod and washer interface. Crank pin bearings are manufactured with the highest-quality hot-rolled steel and case hardened to 58-62 RC.
