The Hot Rods 4259 Stroker Crankshaft is a complete, ready-to-install performance replacement for select 400cc ATV and motorcycle applications. Designed as a premier alternative to a costly OEM crankshaft, this Hot Rods crankshaft is factory assembled and trued to OEM specifications for dependable performance, durability, and consistent engine operation. The increased stroke is designed to provide greater displacement and horsepower while serving as a drop-in replacement in most applications without engine modification.
Each crankshaft includes proven Hot Rods connecting rods, top-end bearings, and crankshaft webs. The assembly is CNC machined and dynamically balanced to accommodate the increased stroke, and it uses the stock piston in most applications. Gears are manufactured to a quality level of DIN Class 9 or higher for reliable engagement and long-term service. The crankshaft is also fully rebuildable with genuine Hot Rods connecting rods and bearings, making it a practical choice for performance builds and future engine maintenance.
Fitment includes 2004–2008 Arctic Cat DVX 400 models, 2003–2006 Kawasaki KFX 400 models, and the 2005 Suzuki DR-Z400S. For additional displacement and horsepower potential, this stroker crankshaft can be matched with Cylinder Works Big Bore cylinders. Verify the motorcycle or ATV model year and engine configuration before installation to confirm compatibility. Manufacturer: Hot Rods. Brand: HOT RODS. Manufacturer part number: 4259.
