HOT RODS Crankshaft 4075

If you're serious about extracting maximum performance from your ATV's engine, a purpose-built crankshaft assembly is non-negotiable. The HOT RODS Crankshaft 4075 arrives factory-assembled and trued to OEM specifications, eliminating guesswork and letting you focus on tuning rather than fabrication. With proven connecting rods, top-end bearings, and webs engineered for durability, this complete assembly meets or surpasses OEM performance standards right out of the box.

This crankshaft is fully rebuildable with genuine HOT RODS components, giving you long-term serviceability and the ability to customize your build without replacing the entire assembly. Whether you're running a TRX400EX, KFX/LTZ 400, Banshee, Warrior, or Raptor, HOT RODS' six long-stroke applications eliminate expensive machine work—special pistons are engineered to fit these platforms directly, simplifying installation and reducing costs.
