The Hot Rods Complete Bottom End Kit is designed for 2003-2014 Yamaha YZ 250 models, providing all necessary components for crankshaft installation and engine rebuilding. Each kit includes a factory-assembled Hot Rods crankshaft, main bearings, seals, and a complete engine gasket set. The crankshaft is available in a heavy-duty OEM replacement or a stroker version, which increases stroke length depending on the application. Some applications may require cylinder head modifications. The crankshaft is fully rebuildable with genuine Hot Rods connecting rods, ensuring long-term durability and performance.
