This is a matched pair of 550 High Performance motors for Kid Trax Dodge Ram Pickups, Chargers, and Land Rover Defenders. Also for Kid Trax Firetrucks that use a 19 tooth pinion on the motors. Included is 2 Hardened Steel First Gears and 4 sealed Ball Bearings. Just unbolt your old motor and bolt in the new one. Pull out the plastic first gear and slid the new gear & bearings in. 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.
* 4 Spade connectors for quick motor installation and removal.
* Hardened steel pinion gears installed on the motors with threadlock.
* Hardened steel first gears with 2 ball bearings for each gear.

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.
