HOT RODS Crankshaft 4046

If you're running a long-stroke build on your ATV, a properly engineered crankshaft is non-negotiable—it's the foundation of reliability under sustained high RPM loads. The HOT RODS 4046 arrives factory-assembled and trued to OEM specifications, eliminating the guesswork and machine work typically required for stroker applications. This is a complete, ready-to-install solution that meets or exceeds OEM durability standards, so you can focus on tuning rather than fabrication.

Hot Rods has engineered six dedicated long-stroke applications across popular platforms, each paired with special pistons designed to eliminate unnecessary machine work and costly modifications. Whether you're running a TRX400EX, KFX/LTZ 400, Banshee, Warrior, or Raptor, this crankshaft integrates seamlessly into your build with minimal additional parts.
