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.

This total break overhaul was actually fun to do because i got everything from etrailer and I knew it was a perfect fit! One year and thousands of miles later I still love it. If your on the fence, take the plunge, you WILL be happy..
Trailer a 25ft 6500 lb boat up an down the East coast in salt water.
I love etrailer everything was perfect
Have not installed at time of writing, but is a perfect match to my old unit! Looking forward to install! Thanks trailer.
I want you to know I am very happy with the actuator. I installed it and have used the boat several times since. The actuator is quality and the service from e-trailer is always excellent. I will continue to use your services as needed.
Buying experience was great from ordering to receipt. Free shipping always makes, the ordering a better experience. Item was packaged very well and hitch was exactly as described. I will do business with etrailer again.
This product has been great. I installed it about 1 1/2 years ago and it works well. The nice thing about is that it can be used on a range of ball sizes. The only thing is that I need to remember to tighten it up onto the ball (when I leave my home) and check it again before leaving the boat launch (just to make sure nobody loosened it while I was away fishing).
The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful.
I started to replace the nut that goes to the backup actuator. I recall a review and looked at the video. No nut replacement, just screw in the actuator. The nut is just used for shipping. The product is excellent and my identical Titan lasted over 10 years of salt water use. Glad to see that the quality has not decreased. Will buy again from etrailer.
Great customer service. I placed the order for a coupler with Bill, shortly I received a notice that the item would be delivered before 8 pm on Wednesday. At a little before 8pm on Wednesday evening the item was at our door.
I only replaced the old unit because the trailer had been in storage for over 10 years and the unit had dried out and the lines were a mess. We were taking the boat over 400 miles and I wanted to be on the safe side.
Not a fan of the screw down coupling
This product is a champ when it comes to trailer brakes the reverse actuator automatically disengages the brakes so you won't have to manually . Easy to install looks good
The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful. There was NO documentation that came with this major item. Next, I was unable to attach the solenoid cutoff for the coupler and determined the solenoid was a different thread size than the coupler's reservoir fitting. I spent extra time and two trips to the hardware store to correct this only to discover that the fitting on the reservoir needed to be removed AND REPLACED with the solenoid connection. The last item relates to the protective cover for the solenoid. A separate part is included that protects the solenoid and its fitting but nothing tells you that this needs to be installed in place of the shorter cover supplied on the coupler. One additional point is the lack of instructions to properly bleed the braking system. It is a little tricky on this item and knowing the correct process would have been helpful instead of relying on internet searches to find help.
Trailer coupler was delivered on time. It bolted up to the trailer ok. However, a disc brake lock out solenoid is in a separate box contained in the shipping box. It threads into the surge brake fluid outlet ok, but the solenoid outlet thread and end shape is a mystery that sent me running around town to locate a fitting with the right thread and shape. Very frustrating that the kit did not have a fitting that would convert to something standard. Still searching after two days of searching. Makes this kit relatively worthless til you solve this problem.
Not sure of actual product performance yet. But you guys really need to add a small instructional sheet. Wasted half an hour trying to figure out fittings before I finally figured out that since reverse solenoid was not attached it replaced the fitting already on the cylinder. Then after I had it together I saw that the longer shield that was included loose for the reverse lockout solenoid could NOT be put on without removing short shield which could not be removed without taking off the brake lines that I had just installed. Half sheet of paper with 2 or 3 sentences is all you would need to include.
Order arrived on time and as described!
Device is sturdy and put together well. My problem was when I unloaded it I could not for the life of me get the coupler to unlatch from my trailer hitch. Despite numerous attempts to get creative, I finally had to remove the hitch from my truck and drive off, and my trailer hitch is still attached to the coupler just hanging there. Disappointed.
very good
poor delivery
out ti me
Well made and reasonably priced
Excellent service and time of delivery! Recommended
The latch is a pain, it's always getting stuck. It is such a pain that I just ordered the Demco. Save yourself the headache and buy the better product from the get go.
CUSTOMER SERVICE : A++
VENDOR INTEGRITY: Item appears as advertised. No used parts detected.
PRODUCT QUALITY: Untested at this requested evaluation due to needed repair.
PACKAGING: Poor - Product arrived with minor damage. Required taking to machine shop to repair. Unwelcome delay and expense.
INSTALLATION: No printed installation instructions; online instructions result in "file not found".
Love the coupler, heavy, built well, nice unit. I only wish e-trailer would of notified me that it was on back order prior to taking my money. Ended up moving a vacation back about a month because of it.
I replaced a twenty four year old coupler with the Titan T4750820.
My previous system had a separate coupler, hydraulic pack, and battery box. I could not keep up with the effects of salt water and time. It became a maintenance and safety nightmare.
The installation of a titan hydraulic coupler and a Tekonsha P3 brake controller has restored my confidence in my braking system.
The staff at etrailer.com was first class in answer all my questions and making sure I got the right gear the first time.
Do you have a question about this Brake Actuator?
