Features to know about

Versatile Fit: 5-Position Adjustable Channel with Built-In Drop

The 5-position adjustable channel makes it easy to line up your coupler exactly where you need it. You can mount a lunette ring, clevis, or standard ball coupler (each sold separately) at the right height so the trailer stays level. The built-in drop is a big help when setting up tall trailers, giving you extra flexibility without needing extra parts.

Consistent Braking: Surge-Style Hydraulic Operation for Disc Brakes

This hydraulic actuator uses surge pressure to apply smooth braking when your tow vehicle slows down. As the trailer moves forward during deceleration, the actuator contracts to send hydraulic pressure to your disc brakes. It’s a simple, reliable setup that keeps braking consistent and helps prevent uneven stops on heavy loads.

Built for Heavy-Duty Use: 20,000 lbs GTW and 2,000 lbs Maximum Tongue Weight

With a 20,000 lbs gross towing weight and 2,000 lbs maximum tongue weight, this actuator is made for serious work. The sturdy steel body resists bending even in jackknife situations, keeping everything working straight and steady under pressure.

Corrosion Resistance: Zinc-Plated Finish for Long-Lasting Protection

The zinc coating holds up against rust and corrosion, which is especially useful if your trailer sees wet or salty conditions. It keeps the actuator looking good and working freely through years of use without seizing or flaking.

Built-In Shield and Breakaway: Added Safety at Every Stop

A built-in shield protects the solenoid valve area (solenoid sold separately) from road debris and impact, while the included breakaway kit provides important safety backup. If the trailer were ever to come loose, the breakaway system engages the brakes automatically to bring it to a stop.
