This Lippert Electric Brake Assembly is a genuine replacement part for a wide variety of travel trailers, RVs, and other trailer types. Please reference your original equipment label before purchasing. This electric brake assembly is compatible with 14.5-to-16-inch wheels, made for axles rated 4,000 to 7,000 pounds, and goes on the right side of the trailer (curbside/passenger side). This brake assembly implements an electric actuation system to safely stop your trailer. With no actuator or hydraulic lines, installation is easier than hydraulic brakes (hardware sold separately). It is easy to manually adjust to fit your trailer's needs.
