Features to know about

Smooth Trailer Control: Electric Lockout for Easy Backing

The built-in electric reverse lockout keeps the brakes from engaging when you back up. It wires into a 5-pole flat, 6-way round, or 7-pole connector so it automatically activates when you shift into reverse. That means you can back up a steep driveway or maneuver into a tight spot without the brakes dragging. A protective shield around the solenoid valve helps keep it safe from road grime and moisture.

Level Towing Setup: 5-Position Adjustable Channel

The offset adjustable channel has five mounting positions for your coupler (sold separately), which makes it simple to line things up for a level tow. The built-in drop design works well for tall trailers, letting the coupler sit lower beneath the actuator tube so your setup stays even. Whether you’re using a standard ball coupler, lunette ring, or clevis attachment, the channel gives you flexibility to match your trailer height.

Reliable Braking Power: Hydraulic Surge Design for Disc Brakes

This bolt-on surge actuator delivers solid hydraulic pressure to disc brakes rated for up to 20,000 lbs gross towing weight and 2,000 lbs maximum tongue weight. When the tow vehicle slows down, the actuator’s telescoping movement applies force to the master cylinder for smooth, consistent braking. The roller design inside the slide reduces resistance so braking feels more direct and predictable.

Built to Last: Durable Steel Construction with Primed Finish

The outer casing comes primed and ready for paint so you can match it to your trailer and protect it from corrosion. The zinc-plated inner slide resists rust in wet or salty conditions, and the sturdy steel housing stands up to bending forces in jackknife situations. A built-in breakaway kit adds peace of mind by stopping your trailer automatically if it ever becomes disconnected.

Easy Installation: Bolt-On Fit for 3" Channel Tongues

Mounting is straightforward thanks to its bolt-on design made for straight, 3" wide trailer tongues. The setup is clean with no welding required, and once installed, the actuator gives reliable braking performance trip after trip.
