Features to know about

Heavy Loads, Smooth Stops: Hydraulic Surge Power for Disc Brakes

This actuator uses a hydraulic surge system that synchronizes trailer braking with your tow vehicle for steady, controlled stops. As the trailer pushes forward under deceleration, the actuator telescopes to pressurize the master cylinder and deliver consistent hydraulic pressure to disc brakes. It’s rated for up to 14,000 lbs with a maximum tongue weight of 1,400 lbs, giving you the confidence and control you need when towing heavy loads.

Tough Build: Weld-On Steel Housing for Long-Term Use

The durable steel construction stands up to stress and resists bending even in tight jackknife situations. Since it’s designed for weld-on installation on a 3" wide channel tongue, once it’s mounted, it’s there to stay. The primed finish adds another layer of protection, ready for paint or further coating to match your trailer and keep corrosion at bay.

Flexible Setup: Adjustable Channel with 3 Mounting Positions

The built-in adjustable channel makes setup easier by letting you fine-tune coupler height. With three mounting positions providing a vertical adjustment range of 4", it’s simple to line things up so your trailer sits level. The standard heavy-duty coupler fits a 2-5/16" ball and gives you solid engagement every time.

Reliable Motion: Roller Design for Straight-Line Operation

Inside, a unique roller design keeps movement smooth and direct. It reduces resistance as the actuator telescopes, so braking feels more linear without jerky starts or stops. That straight-line motion helps maintain consistent braking force, especially under load.

Extra Safety: Built-In Breakaway Kit

The integrated breakaway kit adds an extra measure of protection if the trailer ever disconnects. It automatically applies the brakes to bring the trailer to a stop, giving you peace of mind every time you tow.

Video Transcript for All About the Dexter Adjustable-Channel Brake Actuator

Today, we're going to take a look at the Titan weld-on adjustable channel disc brake actuator for the 2-5/16" diameter ball. Has a 14,000 pound weight capacity.Now this hydraulic actuator will synchronize your trailer brakes with your tow vehicle brakes. Basically, what happens is when you apply the brakes in your tow vehicle, the deceleration occurs and the momentum will push your trailer toward the rear of your vehicle. So with the surge brake system, this actuator is triggered as your trailer moves forward while the tow vehicle slows. So the actuator will telescope applying force to the master cylinder that's back here, which in turn will supply the necessary hydraulic pressure to engage your trailer's brakes.This one has a unique roller design. It has rollers right here and right down here.

They reduce resistance during the telescoping to create straight line movement. And if you notice they have grease zerk fittings on the ends that you can put a grease cut on there and lubricate the rollers.Now, this is a sturdy, durable steel construction. Resists bending in any jackknife situations. It does include the adjustable channel and the coupler on this. You can see the channel does have four mounting holes.

So it gives you three, one, two, three, different mounting positions for the height of the coupler, for the range of the height of the coupler is four inches.It does include the breakaway kit right here. You can see the hook on the end on this chain. What you'll do is take this chain and hook it to your tow vehicle. So what happens is it's a safety in case your trailer comes detached from your tow vehicle, what will happen is it would cause the chain to pull this lever, which would activate your master cylinder again, apply the brakes on a runaway trailer.It does have a nice prime finish to it. And as I mentioned, it is a weld-on installation.

Application for this actuator is disc brakes. The ball size that the coupler fits on is a 2-5/16" diameter. Mounting this, it's designed to mount to a three inch wide channel tongue. Weight capacity, again, is 14,000 pounds. Maximum tongue weight capacity is 1400 pounds.Bet that should do it for the review on the Titan weld-on adjustable channel disc brake actuator for the 2-5/16" diameter ball..
