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 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*. - 4 Steel Ball Bearings. - 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!
Just like when modifying a real car, modifying a Power Wheels voids all warranties. If you have made any non-MLToys modifications to your car you should reach out to our tech support first to check compatibility.
I purchased the stage IV kit for my grandson's Artic Cat, which was converted to 24 volts. This was a simple plug and play upgrade, as the motors were already assembled to the gear boxes. The instructions that came with the kit were clear and easy to follow. The amount of torque and power is significantly more than stock. His Artic cat goes through the grass now with no issues at all. After one week, we had a failure in one of the transmission cases, as some of the plastic was being shaved inside the case. It turns out the axle was slightly bent, which causes significant wear quickly to the transmission housing with these more powerful motors. I had no idea to check this when I assembled everything. I would suggest that ML Toys should comment on checking this after assembly. Anyway, they sell empty gear cases for $6, so it was a cheap fix.
Bought these to re-build a project jeep hurricane for my son who also races it in figure 8 demo derbies, so far has held up awesome! I did break 2nd gear but had a spare box and added the brake modules, so far so good!
