Use this actuator to synchronize your trailer brakes with your tow-vehicle brakes. Over-center latch mechanism only engages when the actuator is fully seated on 2" hitch ball. Designed for hydraulic disc brakes and 3x5 straight tongue.
Features:
Specs:
When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the actuator is triggered as your trailer moves forward while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at Dexter DX7.5L Weld On Disc Brake Actuator with the electric lockout and it's designed to fit onto a 2" hitch ball, has a 7,500 pound weight capacity. Now you can use this actuator to synchronize your trailer's disc brakes with your tow vehicle brakes. How this hydraulic actuator will activate the trailer's brakes when your tow vehicle slows or stops. Basically what happens is when you apply the brakes in your tow vehicle, deceleration occurs and the momentum will push the trailer toward the rear view vehicle. So with a surge brake system, the actuator is triggered as your trailer moves forward while the tow vehicle slows.
The actuator, the inner portion here will telescope back, which applies force to the master cylinder in the back here, which in turn supplies the necessary hydraulic pressure to engage your trailer's brakes. Now up front, you'll notice has this nice, low profile, coupler latch to ensure a nice, easy, secure connection. And we call it low profile 'cause it doesn't have any large latch. Some of your actuators have a large trigger latch that sticks up high and that can end up getting damaged or bent. This one is pretty low profile, so nothing's gonna really damage it.
And it uses an over center latch mechanism, which will only engage when the actuator's fully seated onto your 2" hitch ball. And just to demonstrate that, I happen to pull, here's a 2" hitch ball. We're gonna show how it attaches to it, but basically first thing you want to do is pull out the safety pin here and it's tethered so you don't lose it. And that'll release it, and then to open the latch, there's this portion up the top here, this little dome portion, it's spring loaded. Slide that over and it'll pop up.
Now with it open, you're ready to attach to the ball. So if we lift this up, you can put the ball underneath it and you can see with it over the ball, it'll go right in place. And then all you have to do is push this down and it'll close right on it. It's locked onto the ball. And then for safety, you do wanna put this pin right back through the hole, slide that all the way through, and that'll prevent that latch from coming up.
Even if something hits it and releases it, you can see it won't let it go up far enough, it'll still stay connected to the ball. And then to remove it, to detach from there, just pull out your safety pin, open up your latch, and it'll let you remove it from the ball, just like that. So very easy to connect and very easy to remove. I gonna put our pin back in there. Now this does include the breakaway cable you can see here. Now breakaway cable is required by law. This will prevent a trailer runaway situation. Basically what you'll do is take this metal hook on this end and this will attach to your tow vehicle. And then what'll happen in a case if your trailer becomes detached from your tow vehicle, it will pull on this cable, which again would apply the latch onto your master cylinder, which would apply the brakes and prevent a runaway situation. Now this actuator does include a little electric reverse lockout. I turn this on its side. You'll be able to see it in the very back here. This is a solenoid. It's an electric reverse lockout solenoid. It'll let you back up without actuating your trailer brakes. Basically, this lockout on this trailer brake actuator will automatically activate when you shift your tow vehicle into reverse. This solenoid right here wires into your trailer connector, which connects to your tow vehicle so that it can detect when you go into reverse And when you're in reverse, the solenoid ensures that the hydraulic actuator will not activate your trailer's brakes and thus allows you to back up your vehicle. Now, to use this electric lockout feature, you must have a five-way flat, a six-way round, or a seven-way trailer connector on your vehicle. The master cylinder right down here, this master cylinder is constructed of aluminum rather than plastic and this or steel, because what it'll do, it gives you increased strength and corrosion resistance since it's of aluminum. And up at the top here is also a flush brake fluid filler cap on the top. Now this actuator does have a nice prime finish to it. It is a weld on installation. It is designed to fit on a three inch by five inch straight trailer tongue. And this part is made in the USA. Again, the application for this is hydraulic disc brakes. The ball size again, it fits on, is a 2" diameter ball. And the weight capacity on this is 7,500 pounds. But that should do it for the review on this Dexter DX7.5L Weld on Disc Brake Actuator with the electric lockout for a 2" hitch ball.

Use this actuator to synchronize your trailer brakes with your tow-vehicle brakes. Over-center latch mechanism only engages when the actuator is fully seated on 2" hitch ball. Designed for hydraulic disc brakes and 3x5 straight tongue.Received the brake actuator very fast, and it appears to be very well made. I have not as yet had time to weld it to the swing-away connection, but I don't think it will be a problem.
Updating my old surge brake coupler, I really like this Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc - 2" Ball - Zinc - 7.5K fits 3”x4”trailer tongue, it was easy to install, I did have to drill new holes, I just wish the manufacturer would have included the bolts and the information on how much to torque the bolts to, it’s about “2 drop from my old coupler. etrailer was super fast with shipping !
Delivery was very fast. Quality seems very good. Installation was super easy since my Shorelander swing tongue trailer has this standard hole pattern. I love how it looks and the extra foot of distance I get between the boat and my tow vehicle (so less chance of needing to get my feet wet or crawl through the SUV).
Initially receiving The actuator it was missing the cap that covered the rubber plug to the hydraulic reservoir and the manual lockout key, but after contacting etrailer , they quickly sent out the parts. The hitch was easy to install, and it works as it should.
Pros.
Works great really noticed the difference right away.
Ed W. with etrailer was great to work with helped determine which one to get.
It was a fairly simple install.
Con.
The reverse lockout was further away than my original, just a little, so my brake line was too short.
Auto parts places didn't have a flex that fit the thread. I was doing this on a Sunday so I had to drive across town to a trailer guy who was open for a flex line.
I would give it 4.7 stars if I could would of gave a 5 star had they included a short flex line with the kit.
It's about a 2 hour job with everything you need I spent an extra 2+hours getting a part.
All in all been using for a year and I am completely satisfied.
Great replacement for a damaged actuator. A plan came together and it don't get much better.
The actuator arrived within two days after purchase. It fit perfectly as a replacement. Worked as it should. The top plastic cap was damaged during shipping. The staff were happy to send me a replacement. I am happy doing business with etrailer. Thanks a lot.
I installed this brake actuator on a 3500 lb boat trailer with drum brakes, is working great so far. Needed to replace the existing broken hitch on my trailer and this was a suitable replacement to get the brakes working again.
Finished drum to disc brake conversion on my 1993 year model Bass Cat trailer. Installation went smoothly and the UFP-A60 Actuator replaced the obsolete Atwood Actuator. Shortened the outer member a bit and added a 1" flat bar to the bottom for welding of 4" channel trailer frame.
Fit my Karavan trailer well. Though, the top to mounting bolt holes were perfect, the lower holes did not align with the existing holes in the trailer. Had to drill both these through with a 1/2" bit. Then, mounted perfectly. Also, the brake line and blue/white wires hooked right up.
Worked perfect rebuilding a 1990 boat trailer with drum brakes. The updated coupler is so much easier to use. Bolted on and brake lines conntected with no modifications.
The actuator is an exact match for the one I have. As per your video, I will be able to replace the inner workings and hook up the existing brake line and wiring. The quality is excellent and the price was amazing. Very quick shipping,I live in Canada. I ordered it on Monday and it was in my driveway this morning on Friday. Very pleased doing business with etrailer. Thank you
Talked to an "expert"...expert recommended this actuator, based on my 3"×5" trailer tubing. Your "experts" need to learn to ask more questions, as i was puzzled as to how to install it...in showing pictures to your ONLINE experts, he suggested a very slightly different product, strangely with the same midel # but different bolt pattern. I am very frustrated with etrailer
It’s a great looking product. I will need to find the fitting to connect the electric lockout solenoid…
Fast delivery,no shipping damage! Direct replacement for my Magictilt boat trailer.
We are a trailer repair company. We purchase the actuators for our customers. But we have had a lot of experience dealing with Dexter/UFP products. We try to only buy the best products available for our customers. That is why we buy Dexter/UFP products on a regular basis.
Perfect fit for my boat trailer. Only complaint is the surge brake backup plug is not attached by a stainless steel cable. It’s just loose so I have to keep track of it so I can use it when backing up a grade.
Shipping was quick and it was packaged nicely. Exact fit for my 2013 single axel Karavan trailer.
I only used the surge brake, that was an easy replacement in my trailer.
Exactly what I needed. Fit perfectly and easy to install.
By far the best service in the industry! Everything fits as it should.
Perfect replacement. Installed without any problems.
Just what I wanted. I am building a custom trailer for my vintage boat. I have used these actuators in past projects. etrailer has great pricing and fast delivery every time.
Haven't installed it yet but seems to line up perfectly. Great quality as with all Dexter products. The low profile is slightly shorter than my old style pull down latch.
