Stage III kits are best for vehicles running 18 to 24 volts on a tight budget. If you're tearing up first gears you'll want Stage II or IV. - Performance 775 Motors with Internal Fans & the newest 7R Gearbox design.
Stage IV kits are the most durable option for 18 to 24 volt vehicles. - Performance 775 Motors with Internal Fans, Steel Pinion Gears, Steel First Gears on Ball Bearings, Race Grease, & the newest 7R gearbox design. Torque option is only needed for pulling, steep hills, or extra tough terrain.

All of our Staged Motor/Gearbox kits are sold as matched pairs, meaning the price you see is for one complete vehicle. These kits work with all Jeep Hurricanes, Dune Racers, Stingers, and Baja Extremes. Does not work with the 6v Lil Dune Racer.
Please read our How to Start Modifying Guide and Staged Upgrades Explained Guide before making your selection.

We highly recommend a
Brake Reduction Module with all Staged kits to increase gear longevity and driver comfort unless you have steep hills.
