For years, this UFP-style surge brake actuator has been the gold standard for boat trailers. Its bolt-on, low-profile design looks sleek on your trailer, and it comes with both electric and manual reverse lockouts. Made in the USA.

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.
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.
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.
Most surge brake actuators have either an electric or manual lockout, if they even have one at all. They don't let you pick one based on your towing setup, but this actuator does.
The solenoid for this electric reverse lockout is designed to tie 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. That said, if you have a 4-pin connector, or if you're unable to get the solenoid wired correctly for some reason, you won't get the full benefit from this automatic lockout.
Even if the solenoid is wired correctly, having a manual lockout option as a backup is great in the event that:
Activating the manual lockout is easy, just put the lockout pin in place as shown above. This will prevent the actuator from getting pushed in, which in turn keeps your brakes from activating while you're in reverse. Just don't forget to remove the pin when you're ready to pull forward again.
Quick Tip: To greatly reduce your chances of losing this pin, you might want to include it with your boat keys, tackle box, or something else you can't live without for a day on the water. Or, if you're towing with a different vehicle than you normally do, add "put manual lockout pin in glovebox" to your pre-trip checklist.
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.

Worked well! Matched advertising
Shipping was quick and it was packaged nicely. Exact fit for my 2013 single axel Karavan trailer.
Fit perfectly, easy installation
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.
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.

Still working just fine after one year.
Fast free shipping, great job!
Good selection and fast shipping!!!
Great customer service. I have been telling friends family about how you helped me get my wrong order and get the right one. I want to thank Will for being so helpful and make me not fill like dummy. My only trailer need place for life.

Wow Kenny! That is really great to hear. Thanks for coming back and leaving a review to say so! I will make sure Will gets a chance to see this review, too. I know he will appreciate your kind words. :) We will be here whenever you need us next!
Product is perfect, preferred over the big cumbersome actuators. Works great.
It fit great. It took a little tweaking to adapt it to my trailer, the bolt-on housing was welded on my trailer so I removed the outer housing. That led to the rollers falling out. Once I managed to get that all straightened out the brake cylinder ass’y slid right in.
Great supplier with great products
Works as it should. The mechanic stated it is well built and was easy to install. I have had no issues as of yet after one year of service.

Been a year and no issues . Works as it should very happy with this.
Works like a champ. Brakes on my trailer had not worked for years, After several fluid flushes to get all the moisture and air out we have Great brakes again, will work in most all A60 tongue configurations.

So happy to hear that, Jay! Bet that's load of your shoulders having the brakes squared away on your trailer again. What are you hauling?
It was a perfect fit replacement unit!
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.
its a excellent product but it will not fit our trailer
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.
To receive the part in 24 hours was incredible. Great service from a great team at etrailer. Once the weather gets better, I’ll be installing the new coupler.
The actuator kit I bought was a perfect replacement for my 2003 Skeeter EZ Loader trailer! My trailer set up only allows use of inner member of the complete actuator assembly. Buying the inner member only was a higher price for some reason.
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).

After a year the actuator has been working great. I really enjoy having less braking load on my tow vehicle for both safety and wear and tear reasons. My only issue is that the plastic access cover became loose and was lost on the road.
Super fast shipping and an exact replacement for my Magic Tilt trailer.
This was a smooth transition. I pulled the two mounting pins and slid the old unit out and did the same to the new unit and slid it in the welded housing on my trailer. Bled out the air and within 30 min the job was completed. Simple & convenient. My old unit was 26yrs old.
Great replacement for my boat trailer actuator. One issue was the 4 bolt fastening to the trailer was not a perfect match. Top two bolts were exact but bottom two bolts ended up underneath the trailer frame and not through the existing bottom holes. Had to bore out the actuator holes a little then bolts would run through and completely secure to below the trailer frame. The ordering process was fantastic. Joshua was excellent and knowledgeable and made sure I was ordering the correct part.
Great quality for my replacement project. It might be helpful to include on center measurements for the mounting holes. I had just enough room to drill new holes, so it worked out fine. Thanks!

My new actuator showed black splotches on the surface after a few months. Dexter suggested I spilled something on it. Now the surface is covered with black spots and more obvious corrosion is on the hitch and safety cable connections. Otherwise the actuator works fine, its just unsightly. My old actuator was 10 years old and has been outside in marine air for a year, showing no additional corrosion. Thanks

Everything is working as it should and helps me feel secured when towing my boat. I coated it with WD40 over the winter to protect it.
