Features to know about

Strong Braking for Heavy Loads: 12,500 lbs GTW Capacity

This actuator is built to handle serious weight, rated for up to 12,500 lbs gross towing weight and 1,250 lbs tongue weight. Its hydraulic surge design automatically applies your trailer’s drum brakes when your tow vehicle slows down, giving you confident stopping power without needing an electrical hookup.

Smooth Operation Every Time: Unique Roller Design

The internal roller setup keeps movement straight and smooth when the actuator telescopes. That means less resistance, no jerky motion, and steady braking force. It’s a small difference in design that makes a big difference in how the trailer behaves when you stop.

Easy Fit for Tall or Custom Trailers: 5-Position Adjustable Drop Channel

The built-in adjustable channel offers five mounting positions for your coupler attachment (sold separately). The offset drop is especially handy for tall trailers because it lets you mount the coupler below the actuator tube for a more level setup. You can dial in exactly where you need it so your trailer sits right behind your tow vehicle.

Built to Last: Zinc Finish and Heavy-Duty Steel Construction

The actuator’s sturdy steel body resists bending even in tight jackknife turns. The zinc-plated finish adds a layer of corrosion protection, making it a solid choice for gear haulers or trailers that see tough conditions. It’s made for bolt-on installation on a straight 3" wide trailer tongue and includes a breakaway kit for extra peace of mind when towing.
