This is the Stage IV Motor & Gearbox kit for the Arctic Cat. The Stage IV kit is specifically designed for vehicles running at 18 or 24 volts. The Massive 775 motors provide insane amounts of torque for off-road. At 24v they are the fastest motors made for ride-ons! The weakest link in the gearbox, the First Gear, has been replaced with a hardened steel first gear which also has 2 ball bearings for maximum efficiency. The thicker-then-molasses stock grease has been replaced with our Race Grease designed to coat the gears and shafts to reduce drag. The final drive gear has a massive ball bearing on it to reduce friction and increase payload capability! The gearbox housings and remaining gears are a more durable design developed by MLToys' engineers. This setup is for die-hard speed addicts only. Installation is simply removing your old gearboxes and putting your Stage IV in its place. Kit includes:

- 2 massive 775 size Modified Motors with Internal Cooling Fans and flexible wire tabs.
- Torque sleeves on both motor for even more low end powers
- Quick change wire connectors with no soldering installation
- 2 Hardened Steel Pinion Gears
- 2 Hardened Steel First Gears spinning on steel ball bearings
- Aluminum Vented Motor Mounts to keep the motors from twisting on the gearcases.
- 2 MLToys Phoenix 2.0 Gearboxes including massive ball bearings on the final drive gear for lower friction, more speed, and more durability!
- Fully assembled! Just swap out with your stock motor/gearboxes and follow the break-in instructions!

Not for use with lithium batteries unless you use our Soft Start Low Voltage Lithium Module.
