Wiseco Crankshaft Assembly with main Bearings and Gasket set - WPC130,

Precision-trued to OEM specifications and factory assembled 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 Corrosion-resistant surface treatment Top and bottom end rod bores 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 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
