Features to know about

Heavy-Duty Hauling: 20,000 lbs Capacity for Big Jobs

This actuator is built for serious towing. With a 20,000-lb capacity and a 2,000-lb maximum tongue weight, it’s designed to handle heavy loads on demanding trailers. The sturdy steel construction resists bending, even in tight jackknife situations, so it keeps working reliably when the pressure is on.

Smooth Braking Every Time: Surge Design for Disc Brakes

The hydraulic surge system automatically syncs with your tow vehicle’s brakes for a smooth, consistent stop. When the trailer moves forward during deceleration, the actuator telescopes and applies hydraulic pressure to your disc brakes. The unique roller design reduces resistance inside the actuator, giving you straighter movement and better braking response every time you slow down.

Custom Fit: Adjustable Channel with 3 Mounting Positions

The built-in adjustable channel makes setup easier. It has three mounting positions that let you line up your coupler (sold separately) exactly where you need it. That flexibility helps get your trailer level and balanced without extra parts or guesswork.

Built to Last: Weld-On Steel Construction with Included Breakaway Kit

The weld-on design creates a permanent, solid connection to your 3" wide channel tongue. Its durable steel body comes primed and ready for paint or finishing. A breakaway kit is included to help keep your trailer secure if it ever disconnects during towing, adding an extra layer of peace of mind for the long haul.

See what our Experts say about this Dexter Brake Actuator

  • Will the Demco Brake Actuator # DM8202022 Work with Disc Brakes on a Boat Trailer
    The Demco Channel Only Trailer Actuator, part # DM8202022, was designed to be used with drum brake applications only. You could use this actuator with disc brakes, but you would have to replace the master cylinder in the actuator with the Demco disc brake master cylinder, part # 5672. To save yourself some time, work and money, I would recommend going with the Titan Adjustable-Channel Brake Actuator. Titan offers a bolt-on and weld-on version of this actuator. For the bolt-on actuator,...

  • Converting Titan Model 20 Brake Actuator From Drum Brakes To Disc Trailer Brakes
    To switch your Titan Model 20 Adjustable-Channel Brake Actuator # T1899100 from drum to disc trailer brakes you will need to change out the Master Cylinder Assembly # T4749501042. This will change your actuator into the # T4749800 that is for disc trailer brakes. You will need to add a Reverse Lockout Solenoid Valve # T4748800 if you do not already have one to prevent the trailer brakes from locking up when you back up the trailer.
