This package combines our 550 High Performance Motors, Phoenix Gearboxes, and High Capacity 12v Battery for all Powerwheels vehicles that came with 7 or 7R gearboxes. Perfect for giving new life to an old ride on a budget.

The Stage I kit is a great way to add more speed to a Power Wheels without breaking the bank. Kit includes:
- 2 Modified Performance 550 motors - The fastest 550 motors designed for ride-ons today
- 2 Lightweight metal pinion gears
- Torque sleeves on both motors for more low end power.
- Quick-change wire connectors that require no soldering to install and allow fast install/removal of gearcases!
- Bendable motor wire tabs so as not to break as easy as stock ones.
- 2 MLToys Phoenix Gearboxes, the first gearboxes ever designed from the ground up for higher speed ride-on use!
- Fully assembled. Just swap out with your stock motor/gearboxes and follow the break-in instructions!

Motors are warrantied for up to 12 volts of SLA batteries and are often used with 18 volts of SLA batteries (not wrrantied). It is HIGHLY RECOMMENDED to add the Heat Sinks option if you do run 18 volts. Still helpful for 12 volt vehicles too. We strongly recommend using our Metal First Gears when running 18 volts or more.

Hollow Axle - F150, Hurricane, Dune Racer (and all variants), Hot Wheels Racer, some new quads
Solid Axle - Wrangler, Escalade, Mustang, Corvette, McQueen, Porsche GT3, Arctic Cat, and most quads

Our 12 volt battery has 12 amps of running time, compared to 9.5 amps of a stock Power Wheels battery. That means over 30% more run time! Battery also includes a fuse holder with 40 amp fuse and standard 12v Power Wheels female plug. Uses your stock 12v Power Wheels charger (just add 30% to your charging time).

This battery is NOT the same dimensions as your stock battery. However, it will fit into all current vehicles that currently use a grey 12 volt or 2 red 6 volts. Some models will required the white battery strap to be unscrewed.
