This is a matched pair of 550 High Performance motors for the Hunter Products 12v Monster Jam Grave Digger. Not for Bravo or Power Wheels brand. Just unbolt your old motor and bolt in the new one. These motors will add significant speed and torque over stock motors. With each pair you get:
* Torque Sleeves around each motor to add more low-end power.
* Built-in Cooling Fans.
* Quick change wire connectors. Makes motors/gearboxes easy to take in and out of vehicle.
* Lightweight metal pinion gears installed on the motors with threadlock.
* Bendable motor wire tabs so as not to break as easy as stock ones.

If you 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.
