Description
If you’re building a high-performance ATV engine, you need a crankshaft assembly that matches your ambitions—not compromises them. The HOT RODS 4005 arrives factory-assembled, trued to OEM specifications, and ready to handle the demands of long-stroke builds without requiring expensive machine work or custom fabrication. This is a complete, rebuildable platform designed by engineers who understand forced-induction ATV applications.
The 4005 assembly eliminates the guesswork that typically comes with stroker builds.
