Tech Tip: If you really just need to replace the inner member of your old actuator and you're confident that you can salvage the outer casing, you can purchase DX99FR instead.


UFP by Dexter: New Name, Same Great Actuator

If you're replacing your old actuator, you're probably looking at this one and thinking, yeah, that looks like mine alright, but doesn't UFP make these? The short answer is that Dexter bought out Unique Functional Parts (UFP) in 2013, changed the name, but kept the awesome design. Rest assured, this is the real deal and not some kind of knockoff.


Back Up a Boat Trailer Easily with an Electric Reverse Lockout

Elelctric reverse lockouts can be summarized in one word: convenient. If you're looking for an actuator that lets you "set it and forget it", this one from Dexter could be a great option for you.


The back of the brake actuator reveals the electric solenoid that engages the electric lockout

The solenoid on this electric lockout ties into the reverse light circuit on your 5-pin, 6-pin, or 7-pole connector so that your disc brakes won't engage when your reverse lights come on. This can make backing up a boat trailer so much easier than using a manual lockout because everything is automatic.


Simple, Secure Connection

Trigger latches on traditional couplers can be kind of a pain to work with sometimes.

For starters, you have to hold the latch up as you lower the coupler onto the hitch ball. Not to mention that the latch can stick out like a sore thumb, so it may get bent or broken by your tailgate or your bumper as you go to hitch up. That's more than just an inconvenience; when your coupler is out of commission, your trailer's not going anywhere with you.

The coupler on this UFP-style actuator negates all of that. Just slide the button on top with your thumb while you lift up the latch handle. Then, place the coupler over the center of your hitch ball and lower your trailer with your tongue jack.


When you can close the latch without forcing it, you'll hear a click. This sound tells you that the ball is seated firmly inside. Then, just re-insert the tethered safety pin, hook up your safety chains and your breakaway cable, and you'll be ready to tow.


How Does a Surge Brake Actuator Work?

When you slow to a stop as you're towing, momentum pushes your trailer toward the rear of your vehicle. When this happens, the surge brake actuator compresses the master cylinder inside, which forces it to push hydraulic fluid out to your brake lines, ultimately engaging your trailer brakes. When you start moving again, the actuator will telescope back out, stopping the flow of fluid back to the brakes and allowing your trailer's wheels to start rolling again.

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).



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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



by:

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.



by:

It’s a great looking product. I will need to find the fitting to connect the electric lockout solenoid…



by:

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



by:

Works great, no issues during installation or usage after 1 year.



by:

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.



by:

Have not use the Actuator yet. However it came in a oversize box. No packing material to protect it. It was damaged when I opened the box. Scratches and damage cable



by:

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 !



by:

Exactly what I needed. Didn't require the outer housing, the insider mechanism slid in nicely as a replacement on my trailer. The etrailer videos for installation and bleeding were very helpful.



by:

I only used the surge brake, that was an easy replacement in my trailer.



by:

By far the best service in the industry! Everything fits as it should.



by:

Excellent customer service and excellent shipping time



by:

Shipping was quick and it was packaged nicely. Exact fit for my 2013 single axel Karavan trailer.



by:

Exactly what I needed. Fit perfectly and easy to install.



by:

Perfect replacement. Installed without any problems.



by:

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.



by:

Fit was seemless to replace an old actuator with the impossible do get landed hitch latch. Changed brakes from drum to disk, and all new lines. What a difference in smoothness (and effectiveness) while braking. Electric lockout in reverse is also a nice feature. Just plusses all around. If you are replacing the same components be very patient with the bleeding process...it will take some time and a lot of pumping.



by:

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.



by:

I slipped this into my boat mate trailer for 2001 moomba. Took about an hour to hook up and bleed the system with a buddy. Works great! If you can use simple tools and are mechanically savvy this is a no brainer.

  • Will Trailer Surge Brakes Apply When Travelling Down Hill
    Hey Kevin, this is a great question but basically it would take more force than cruising down a hill for the surge brake actuator to apply the trailer's brakes. Basically it would take you applying the trailer brakes down the hill. The great thing about surge brakes is that if for some reason the trailer brakes end up applying to hard it would pull the trailer back from the tow vehicle which would stop the braking action. The only time there's a real issue is backing up the trailer up...
