Wiseco Crankshaft Bottom Kit WPC144 with Bearings and Gaskets. 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 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. Unmatched reliability and performance from high-tech materials. Manufactured to exacting standards. Meets or exceeds OEM quality. Direct OEM replacement.
