The Hot Rods Heavy Duty Crankshaft Bottom End Kit - CBK0113 offers an OE-quality replacement solution for dirt bike crankshafts. The kit includes a heavy-duty OE replacement crankshaft with the connecting rod already installed. Additionally, it features a Hot Rods main bearings and seals kit and a complete engine gasket set, containing all necessary gaskets and seals for a full engine rebuild. The inclusion of a wrist pin bearing and various seals (31x40x8, 30x40x7, 20x27x5, 8x24x5.5/10, 14x22x6, 12x22x6, 10x17x6, and 10x17x5) along with two 30x72x19 bearings ensures all critical components are provided. This kit is specifically designed for the 2005, 2006, and 2007 Suzuki RM-Z450 models. It is important to note that the water pump seal is not included in this kit. For optimal compatibility, this kit must be used with the Hot Rods long rod stroker crankshaft 4111 with the OE head.
