The WISECO Crankshaft Kit for Polaris RZR 800 models is factory assembled and precision trued to OEM specifications. It features double-forged Wiseco connecting rods designed for dimensional consistency through improved grain flow, along with shot-peening that helps eliminate residual stresses and smoothly blends the rod forging surfaces.
The crankshaft assembly includes a corrosion-resistant surface treatment, optimized crank pin bearing radial running clearance, and a precision-honed bearing surface. Precision-engineered oiling slots help maximize rod strength and bearing life, while double-drilled small ends provide the piston pin with additional lubrication and cooling to help reduce top-end distortion caused by thermal transfer from the piston.
The kit includes the crankshaft assembly, main bearings, and bottom-end gasket kit. It fits the 2014 Polaris RZR 800, 2011 Polaris RZR 800 4x4, 2013 Polaris RZR 800 4x4, and 2012 Polaris RZR 800 4x4. Distributor part number: WPC223B. Manufacturer part number: WPC223B.
