CRANKSHAFT BOTTOM KIT RMZ250 07-09, WISECO WPC167 SUZ
Wiseco Crankshaft Bottom End Kit WPC167 with Bearings and Gaskets. Precision-trued to OEM specifications. Connecting rods are double-forged for superior dimensional consistency and shot-peened to eliminate residual stresses. Corrosion-resistant surface treatment. Top and bottom end rod bores are case hardened to 58-62 RC. Crank pin bearing radial running clearance is optimized for maximum performance. Precision honing ensures an ultra-round bearing surface. Engineered oiling slots maximize rod strength and bearing life. Double-drilled small ends provide extra lubrication and cooling for the piston pin. Silver-coated bronze phosphor thrust washers with dimpled design increase oil retention and reduce friction. Crank pin bearings are manufactured with high-quality hot-rolled steel case hardened to 58-62 RC.
