Features to know about

Built for Heavy Loads: 12,500 lbs GTW Strength

This actuator is made for serious hauling. With a gross towing weight of 12,500 lbs and a maximum tongue weight of 1,250 lbs, it’s built to handle heavy-duty farm and construction trailers. The sturdy steel body resists bending in tight jackknife situations, and the primed outer casing gives you a clean surface ready for paint. Inside, the painted slide keeps everything moving smoothly under load so you can count on consistent braking when it matters most.

Smooth Braking Every Time: Roller-Driven Surge Operation

The hydraulic surge system activates the brakes automatically when your tow vehicle slows down. Its unique roller design cuts down resistance as the actuator telescopes, keeping everything in a straight line instead of binding or jerking. The result is more predictable braking with disc brake systems and less strain on your coupler and pintle hitch setup.

Made for Tall Trailers: Drop Channel with 5 Mounting Positions

The drop-style adjustable channel gives you five different mounting positions for the 3" lunette ring. This layout makes it easy to match up to tall trailers while keeping your setup level with your tow vehicle. The offset design also gives you extra flexibility for custom builds or when you need more clearance between your trailer tongue and hitch.

Ready to Customize: Weld-On, Primed Finish

The weld-on construction gives you a rock-solid mount right on a 3" wide trailer tongue. Because it comes primed instead of painted, you can weld it directly without burning through paint or coating, then finish it however you want once it’s installed. The result is a clean, durable fit that’s ready to handle years of hard use.

Added Safety: Built-In Breakaway Kit

A built-in breakaway kit is included to help keep your trailer under control if it ever disconnects from the tow vehicle. It’s a simple but important safeguard that adds peace of mind every time you tow heavy loads.
