This package combines our 550 High Performance Motors, Phoenix 2.0 Gearboxes with steel first gears, Brake Reduction Module, and a Lithium Module. It is for all Power Wheels vehicles that came with 7 or 7R gearboxes. The lithium battery setup is great for more speed but does come at a cost of reduced runtime. The Stage II motor gearboxes will increase speed in onroad and light offroad uses. Go with the SLA combo kit if you desire the runtime or more offroad power.

Stage II Phoenix 2.0 Motor/Gearbox Kit

The Stage II motor/gearbox kit is specifically designed for vehicles running at 12-20 volts, where these motors are significantly faster than the original motors and more durable. This setup is for die-hard speed addicts only. Kit includes:

• 2 massive 550 High Performance motors with internal cooling fans and ball bearings.
• Hardened Steel Pinion Gears attached to motors.
• Torque sleeves on both motors for even more low end power.
• Quick change wire connectors with no soldering installation.
• 2 MLToys Phoenix 2.0 Gearboxes including stronger nylon gears, improved lubricating, stronger housings, and low friction race grease.
• 2 Hardened Steel First Gears spinning on ball bearings.
• Fully assembled! Just swap out with your stock motor/gearboxes and follow the break-in instructions!

Lithium Module

The Lithium Module will allow you to use 18 or 20v lithium power tool batteries in your ride-on. It solves the two big problems people run into when they wire a lithium battery in:

• Low-voltage cutoff. Many tool batteries don't have one. If you over-discharge a lithium battery it won't charge again and may catch fire. At 15.5 volts the LED lights up and an alarm sounds. When the voltage drops below 15 volts for 60 seconds the power shuts off. Make sure this voltage minimum is within your battery manufacturer's guidelines.
• Soft start. The initial "punch" a lithium battery sends through the motors, gears and switches normally destroys them. The module gradually applies power to the wheels over a few seconds if it senses too much amperage surge. A regular voltage reducer won't stop the initial punch and it limits top speed. With this module you keep the same top speed, and the wheels can still spin on pavement. In high traction areas the module limits the initial amperage surge that does the damage, and that's where you'll see reduced wheel spin.

Please select the battery adapter type for your battery. Black & Decker, DeWalt, Makita, Milwaukee or Ryobi. If you use your own adapter it MUST have 14 gauge wire or larger. Smaller wire can lead to failure or fire.

Brake Reduction Module

Every time your kid lets off the throttle the car slams to a halt, bashing their head into the windshield and putting unnecessary strain on the gears. That's because of an electrical braking built into each Power Wheels, and as you increase voltage the effect gets stronger.

This simple addition greatly reduces that braking. It goes in-line with your existing wiring.

• Smoother stops. The car coasts about 10 ft instead of stopping dead.
• Less strain on the gears every time the pedal is released.
• Works with any voltage and in most vehicles using a plunger-style foot pedal switch.
• Works with the Lithium Module.
• NOT compatible with cars that have an electronic speed control, including our Titan and v2.0. If you add one later, take the Brake Reduction Module out.
• We don't recommend it where the car is driven on hills.

THIS WILL INCREASE THE STOPPING DISTANCE OF YOUR VEHICLE.

Common questions

Does it fit my car?
It's for Power Wheels vehicles that came with 7 or 7R gearboxes.

Lithium or SLA combo?
Lithium gives more speed but less run time. Go with the SLA combo kit if you desire the runtime or more offroad power.

Do I also need a speed controller?
No. The Lithium Module does the soft start and the low voltage cutoff.

Can I use a 24v lithium battery?
No. The module only works with 18-20v lithium batteries. Any higher and it will fail.

Before you use lithium batteries

• A cheap or old battery may swell or even catch fire, with or without this module. A ride-on car has a high amperage demand, and the heavier the car or the tougher the terrain, the higher it gets. If the battery can't supply it, bad things can happen. This module won't prevent that.
• You still need motors and gears capable of 18-20 volts of power.
• The soft start is not adjustable.
• Running 2 lithium batteries in parallel may overpower the module from the increased discharge rating and is not warrantied. Do not use batteries with variable voltage.
• Secure the battery holder and the module to the car with double-sided tape, screws, hot glue or whatever works for you. Bouncing electronics is never a good idea. The larger the space, the better the module will cool.
• Lithium batteries usually have a much lower amperage rating than an SLA battery. Stock Power Wheels batteries are 9.5 amps. The lower the amperage, the less run time you'll get, and increasing voltage reduces run time too. We still prefer SLA batteries for kids to get the most fun out of ride-ons for this reason.
• Not waterproof.
• Unplug when not in use.
• You can use our Voltage Reduction Module to connect our Lighting Kit. Attach it to the black and white wires leading from the module.
