This hydraulic surge actuator syncs the trailer’s disc brakes with your tow vehicle’s brakes for smooth, even stops. When you slow down, the actuator telescopes forward to apply the right amount of pressure through its master cylinder, giving you confident braking without harsh jerks or delays. With a 12,500-lb capacity and 1,250-lb maximum tongue weight, it’s built to handle heavy loads and multi-axle setups with consistent performance.
The electric reverse lockout solenoid automatically prevents the brakes from engaging when you shift into reverse. Powered by your tow vehicle’s reverse light circuit through a 5-pole flat, 6-way round, or 7-pole harness, it makes backing up inclines or tight spaces simple. You don’t have to climb out to set a manual lockout—just shift and go.
The zinc-plated finish protects the heavy-duty steel body from corrosion, making it a solid choice for trailers that see water, salt, or rough weather. The plating shields critical surfaces from rust while keeping the sturdy frame intact so it won’t bend even in tight jackknife turns. The actuator weighs about 52 lbs and bolts onto a 3" wide channel tongue for a secure fit that stays true under load.
A built-in breakaway kit provides extra protection if the trailer ever separates from the tow vehicle. The internal mechanism applies the brakes automatically to bring the trailer to a stop. It’s one less thing to add and one more level of safety built right in.
Inside the actuator, a unique roller design reduces resistance during telescoping so motion stays straight and smooth under braking force. That means less binding, less wear on internal parts, and more consistent braking every time you tow.

Works fine, But there are many times that a bypass or lockout is needed.

Hey Matt! I asked Dexter about this, and here is what they said. Make sure the actuator is fully extended back out. This will take the pressure off. If you are having an issue getting it extended. You can block the wheels and slightly pull forward. Once off make sure there are no burrs on the ball or in the ball coupler. Also make sure the ground is level. Is this a new actuator or ball ? Let me know if this helps or not!

The solenoid valve for the Titan brake actuators has one eighth inch pipe NPT threads on the make end and three eighth - 24 inverted seat threads on the female side that a three sixteenth size brake line would install to. We do have a video that is useful about the solenoid and installation.

The Dexter hitch is performing well, although I have found it needs to be lined up precisely to the ball to connect...low tolerances that way. Another concern I have, although it has no direct bearing on this hitch, is that I recently learned some jurisdictions are only allowing tandem trailers with electric/hydraulic brakes...I guess they feel solely hydraulic surge brakes are "less" safe? You guys might consider a small note about this in your descriptions.

EASE OF INSTALLATION: Definitely not plug and play. RELIABILITY: Excellent. DURABILITY: Product used exclusively in salt water environment. Still looks new. No Rust! RECOMMEND TO OTHERS: Yes, but know you are in for a major task.
