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:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • Electric reverse lockout lets you back up without actuating trailer brakes
    • Solenoid activates automatically when you shift into reverse
  • Low-profile coupler latch ensures easy, secure connection
    • Over-center latch mechanism only engages when the actuator is fully seated on hitch ball
  • Aluminum master cylinder is better at reducing corrosion than cast steel master cylinders
  • Primed finish
  • Weld-on installation
  • Made in the USA


Specs:

  • Application: hydraulic disc brakes
  • Ball size: 2"
  • Mounting: 3" x 5" straight tongue
  • Capacity: 7,500 lbs
  • 2-Year limited warranty


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.

by:

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:

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:

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:

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:

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.
