This is a matched pair of 550 High Performance motors for Roll Play Silverados. Just unbolt your old motor and bolt in the new one. These motors will add significant speed over stock motors plus will work at up to 18 volts of power. With each pair you get:
* Torque Sleeves around each motor to add more low-end power.
* Built-in Cooling Fans.
* Spade Connectors for quick wire installation. Makes motors/gearboxes easy to take in and out of vehicle.
* Lightweight metal pinion gears installed on the motors with threadlock.

If you are going to run 18 volts or just want your motors to have a long happy life, a set of heat sinks will help keep your motors cool and fast! Our Heat Sinks fit over the torque sleeve and wrap 3/4 of the motor in heat dissipating aluminum fins.
