This package combines our 775 High Performance Motors, Phoenix Gearboxes, High Capacity 24v SLA Battery pack, and Fast Charger. It is for all Powerwheels Dune Racers, Dune Racer Extremes, and other variants of the Duner Racer.

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 and handle 24 volt loads without a care. 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 Teflon Race Grease designed to coat the gears and shafts to make them more slippery and create less heat buildup. The gearbox housings and remaining gears are a new, 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 pre-installed in gearboxes.
- Torque sleeves on both motors.
- Quick Connect Motor Wires
- 2 Hardened Steel Pinion Gears with Lifetime Warranty*.
- 2 Hardened Steel First Gears with Lifetime Warranty*.

- MLToys Teflon Race Grease for even more speed, motor durability, and more run time.
- 2 MLToys Phoenix Gearboxes including stronger nylon gears, improved lubricating, stronger housings, and low friction race grease.
- Fully assembled! Just swap out with your stock motor/gearboxes and follow the break-in instructions!
