Features to know about

Confident Braking on Heavy Loads: 12,500-lb Surge Design for Disc Brakes

This actuator is built to handle serious weight, rated for 12,500 lbs with a maximum tongue weight of 1,250 lbs. The hydraulic surge design synchronizes the trailer brakes with the tow vehicle’s brakes for smooth, reliable stopping. It’s set up specifically for disc brakes, giving you solid braking feel and consistent performance when you’re hauling heavier gear or multi-axle setups.

Straight Tracking Under Pressure: Roller-Guided Telescoping Movement

Inside the actuator, a unique roller system keeps the telescoping action smooth and straight. That design cuts down on binding when braking hard or making tight turns. It’s also built from sturdy steel that resists bending in jackknife situations, so the actuator keeps doing its job even in tough conditions.

Easy Positioning: Adjustable Channel with Three Mounting Heights

The built-in adjustable channel gives you three distinct mounting positions for the lunette ring coupler. With 4? of vertical range, you can dial in the right ride height for your trailer setup. The bolt-on design fits a standard 3 -wide channel tongue, making installation simple and clean without custom fabrication.

Backing Up Made Simple: Electric Reverse Lockout with Shielded Solenoid

The electric reverse lockout solenoid prevents brake engagement when backing up. It activates automatically when your tow vehicle is in reverse—just connect through a 5-pole flat, 6-way round, or 7-pole harness. A built-in shield protects the solenoid from the elements, so it keeps working whether you’re maneuvering on gravel, a boat ramp, or uneven ground.

Built to Last: Zinc Plating and Integrated Breakaway Kit

A full zinc-plated finish protects against rust and corrosion, especially useful around water or road salt. The included breakaway kit provides an extra layer of safety if the trailer ever disconnects unexpectedly. Together, those details make this actuator a durable choice for long-term use on work or marine trailers alike.
