Ensure your trailer is Ready for the Road Ahead™ with parallel brake force to your vehicle, with the Tekonsha Prodigy® Trailer Proportional Brake Control. By gathering the travel speed of the truck and trailer, this replacement controller works to slow down the trailer at a pace on par with the vehicle it is being towed by. Built with a digital display to depict how much voltage is being delivered to a trailer's brake drum when towing or parking. FleetPride is your First Click in Heavy Duty®.
