Backup valve installs in trailer brake actuators with high psi ratings and wires into your tow vehicle so that the trailer brakes do not activate when you shift your tow vehicle into reverse.
Kit includes everything you need to switch your trailer over to disc brakes for improved performance and greater stopping power. Leverlock adjustable-ball actuator features easy-to-use latch and electric reverse lockout.
Replace or add a reverse lockout solenoid to your surge brake actuator from Dexter or Tie Down Engineering to keep the actuator from activating your trailer brakes when you shift into reverse.
