HOT RODS Crankshaft Kit 4409

If you're running a long-stroke build on your ATV, a quality crankshaft assembly is non-negotiable—it's the foundation that determines reliability under load and sustained RPM. The HOT RODS 4409 arrives factory-assembled and trued to OEM specs, eliminating the guesswork and machine work typically required for aftermarket stroker applications. This complete kit lets you focus on tuning and testing rather than sourcing individual components or paying for custom fabrication.

HOT RODS has engineered this package specifically for popular platforms like the TRX400EX, KFX/LTZ 400, Banshee, Warrior, and Raptor—pairing the crankshaft with matched pistons and connecting rods so you avoid costly machine work and compatibility issues.
