Features to know about

Built for Heavy Loads: 12,500 lbs GTW Strength

This actuator is made to handle serious towing. With a gross towing weight of 12,500 lbs and a maximum tongue weight of 1,250 lbs, it’s ready for farm trailers, construction trailers, or any setup that needs strong and consistent braking. The sturdy steel construction keeps its shape even in tight jackknife situations, and the primed outer casing gives you a solid base for paint or corrosion protection.

Straight-Line Braking: Efficient Roller Design

The internal roller system keeps the actuator movement smooth and direct. When your tow vehicle slows down, the actuator telescopes forward with less resistance, sending hydraulic pressure straight to your drum brakes. That means less jerking and more predictable stops every time.

Level Towing Made Simple: 5-Position Adjustable Channel

The built-in drop channel gives you five different coupler mounting positions so you can match the height of your trailer to your tow setup. It’s especially useful for tall trailers that need extra drop to tow level. You can mount nearly any type of coupler—standard ball, lunette ring, or clevis—so your hitch lines up just right.

Protected Setup: Built-In Shield for Lockout Applications

When using an electric lockout solenoid (sold separately), the integrated shield helps protect it from damage while keeping everything clean and accessible. It’s a smart touch that saves you from fabricating your own cover or worrying about debris hitting the valve.

Ready to Weld and Go: Primed for Easy Installation

This surge actuator comes primed and set up for weld-on installation on a straight 3" wide trailer tongue. That makes it simple to fit onto new builds or replacements without extra brackets or drilling. A breakaway kit is included for added safety once it’s mounted and ready to tow.
