Hi Sam, we do not carry any modification or upgrade parts that are specifically made for toy cars.

The type of motors and drivetrain parts that we carry would require replacing the entire rear end of the toy car with a new go kart axle, bearings, bearing hangers and wheels. This would turn the rear end of the toy car into something that could last a lifetime though instead of just lasting a few months or years as most toy cars are designed to.

We have a few customers who fabricated steel frames for their children's toy cars and used go kart parts for the running gear and then bolted the toy car body onto the new steel frame.

Here is a link to a modified toy car forum where you may be able to find an answer to the motor/gearbox question: http://forum.modifiedpowerwheels.com

Upgrading from 12 Volts to 24 Volts would double the power and top speed of the toy car however in doing so it would also double the amount of heat that the motors need to dissipate which may possibly cause them overheat and burn out.

If you like to modify things for speed and don't mind replacing parts if they fail then this would be a good experiment to try. If you want to play it a little more safe though then the 12 Volt battery could be replaced with three 6 Volt batteries to increase the Voltage to 18 Volts instead of 24.

Please let us know if you have any questions.
