Trailer Brake Controllers

Proportional based controls offer a smooth braking response to almost any stop. Through the use of a sensing device, the brake control can determine the tow vehicle’s rate of deceleration and then apply the trailer brakes to match. In other words, Proportional controls deliver power to the trailer brakes in direct relationship to the actual physical deceleration of the tow vehicle.

**Not only do we sell brake controllers, we also install them. Please be aware that the wiring for each vehicle varies based on the factory installs that are on your vehicle. For more information, please contact us.**
