Features to know about

Heavy Loads, Smooth Stops: 20,000-lb Surge Power

Built for serious hauling, this actuator delivers strong, consistent braking for trailers equipped with hydraulic drum brakes. It’s rated for 20,000 lbs gross towing weight and 2,000 lbs maximum tongue weight, so it stays steady and reliable under heavy loads. The surge system activates automatically when the tow vehicle slows, applying hydraulic pressure to the brakes for smooth and controlled stops every time.

Simple Alignment: 5-Position Adjustable Channel

The adjustable channel makes setup easier when you’re dialing in your trailer height or swapping out attachments. With five mounting positions, you can line up the lunette ring exactly where it needs to be for level towing. That flexibility lets you use a variety of couplers or hitch setups without fighting with mismatched heights.

Built to Endure: Primed Steel and Roller Design

The primed steel outer casing and painted inner slide hold up well against wear and corrosion. Inside, a roller design reduces resistance during telescoping movement, helping the actuator glide smoothly in a straight line as it engages. The sturdy build also resists bending in jackknife situations, giving you dependable performance in tough working conditions.

Ready to Weld: Straight 3" Tongue Mount

Designed for weld-on installation on a straight 3"-wide trailer tongue, this actuator provides a solid fit that becomes part of the frame. The primed finish is easy to prep for paint or final coating, so you can match it to your trailer once the welds are done.

Added Safety: Built-In Breakaway Kit

A breakaway system comes pre-installed to engage your trailer brakes if it ever separates from the tow vehicle. It’s an extra layer of safety that helps keep your trailer under control in the unlikely event of a disconnect.
