The Wiseco Crankshaft Kit WPC100 is a complete bottom-end rebuild kit. It includes a precision-trued crankshaft, bottom-end gasket and seal set, crank bearings, and small-end bearings. This kit meets OEM specifications and ensures reliability for high-performance applications. Features include precision-trued crankshaft assembled to OEM specifications, double-forged connecting rods with superior dimensional consistency and improved grain flow, shot-peened rods to eliminate residual stresses and improve durability, and a corrosion-resistant surface treatment for extended lifespan. Case-hardened rod bores optimize bearing surfaces, while optimized radial running clearance maximizes crank pin bearing performance. Precision honing creates ultra-round bearing surfaces, and engineered oiling slots enhance rod strength and bearing life. Double-drilled small ends ensure enhanced piston pin lubrication and cooling. Silver-coated bronze phosphor thrust washers reduce friction and improve oil retention. Crank pin bearings are made of high-quality hot-rolled steel, case-hardened to 58-62 RC. Caged needle roller bearings allow for high RPM operation. Precision-machined crank webs ensure reliability and balance. The kit includes premium main bearings and a complete bottom-end gasket set with all seals and gaskets required for installation. Part Number: WPC100.
