This actuator is made to handle serious weight. With a 12,500 lb capacity and a maximum tongue weight of 1,250 lbs, it’s built for large trailers and steady braking under load. The standard heavy-duty coupler includes a 3" drop, which helps level the trailer when mounted on a 3" wide channel tongue. Everything bolts on securely, so there’s no guesswork during setup.
The unique roller design keeps movement straight and smooth as the actuator telescopes during braking. Instead of metal parts dragging against each other, the rollers cut down on resistance, giving you even pressure to your hydraulic drum brakes. The result is a more controlled stop with less wear on internal parts.
This Dexter actuator is made from heavy-duty steel that resists bending in tight turns or jackknife situations. It comes primed and ready for paint, so you can match it to your trailer and add an extra layer of protection against the elements. Once installed, it’s ready to take the bumps and stress of towing without giving up strength.
Installation is straightforward thanks to the bolt-on design that fits a standard 3" wide channel tongue. You don’t need to weld or modify anything—just line it up and bolt it down. The built-in breakaway kit is included for added safety, keeping your trailer under control if it ever disconnects while towing.
This hydraulic drum brake actuator uses surge action to sync with your tow vehicle’s braking. When the vehicle slows down, the actuator telescopes forward and sends hydraulic pressure to engage the trailer brakes automatically. Since this model doesn’t include a reverse lockout, it’s best paired with free-backing brakes so you can reverse without engaging them.

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Dexter Brake Actuator with a three inch drop. This is a surge-type actuator that's going to bolt over your three inch wide trailer tongue, and it's going to include the standard heavy-duty coupler with the three inch drop so that you can connect to your two and 5/16 inch ball on your tow vehicle. This is going to activate your trailer's hydraulic drum brakes when your tow vehicle slows. So basically, as your tow vehicle slows, the momentum of the trailer is gonna push it forward. And then we are going to have the telescoping function here that's going to apply force to the master cylinder, and that in turn is going to supply the necessary hydraulic pressure to engage your trailer's brakes.
This does feature a unique roller design that's gonna help reduce binding during your telescoping, so it's going to create a nice straight line pull and make sure that your brakes are applied properly. This does have a sturdy, steel construction, so it is going to resist bending and jackknife situations. It's also gonna provide a 12,500 pound capacity with a maximum tongue weight of 1,250 pounds. You can see this does have a primed finish, so it's ready to be painted in whatever color you prefer. They do include the breakaway kit, so you'll hook this onto your tow vehicle.
So if for some reason your coupler we're to become disengaged from the ball or your ball were to become disengaged from the receiver tube on your hitch, this is still gonna be connected. So it's going to pull this lever up and engage your brakes so that your trailer is not just bouncing down the road without anything slowing it down. And this model does not include a reverse lockout, so it is recommended that you equip your trailer with free-backing brakes so that if you we're to drive in reverse it's not going to cause your brakes to be applied even though this will be telescoping. So because this doesn't have the ability to prevent the brakes from being applied itself, it's recommended that you get brakes that have that free-backing option to them so that your trailer's not, the brakes aren't being applied as you're backing up. I do wanna point out the coupler connection here.
So very simple to operate. Lift that up, get that set down on your two and 5/16 ball, and then once it's in place it'll snap closed for you so that you know you have a nice solid connection to your trailer ball. So overall, a really great option. If you are needing that three inch drop for your trailer, this is gonna be a great way to go. That completes our look for today.
Again, I'm Michael with etrailer.com. Thanks for watching.

Have you checked the shock inside the unit. If it isnt set up proper it will cause issues like what you are explaining. Here is what it looks like, Replacement Shock for Titan Model 6 and 10 Brake Actuators # T1242600
