The Dexter DX7.5L A-60 Brake Actuator is a solid upgrade for anyone replacing an older or obsolete unit like the Titan Aero 7500 or the Atwood surge actuator. It’s built for hydraulic disc brakes and rated for 7,500 lbs, giving you dependable stopping power on trailers with up to two brake axles. The coupler fits a 2" hitch ball and installs on a 3" x 4" straight tongue, matching the common bolt pattern of 3" horizontally and 2-1/2" vertically. If you’re rebuilding or modernizing your trailer’s braking setup, this actuator bolts right into place without complicated changes.
Anyone who’s ever tried to back up a trailer with surge brakes knows how frustrating it can be when the brakes grab in reverse. The built-in electric reverse lockout in this actuator fixes that problem. When you shift into reverse, the solenoid automatically activates to keep the brakes from engaging. Just wire the blue lead to your reverse-light circuit and the white lead to ground. That’s all it takes to get smooth backing up hills or around tight corners with no drag or wheel hop.
This actuator is made to handle wet environments like boat ramps and coastal roads. The aluminum master cylinder resists corrosion better than cast steel, so it stays clean inside and out. The zinc-plated outer shell provides strong protection against rust and salt exposure while keeping maintenance low over time. It’s a practical setup for trailers that see water or humidity often.
Hooking up is simple thanks to the low-profile over-center latch design. It only engages once the coupler is fully seated on the 2" ball, so you know it’s locked down before hitting the road. This gives a positive fit that stays secure even under heavy braking, and its low height means easier clearance for accessories or swing-away tongue hinges when space is tight.
The bolt-on design uses standard 1/2" hardware and fits directly over a 3" wide by 4" tall trailer tongue, which makes upgrades fast whether you’re replacing an older unit or setting up a new build. With its simple layout and 19" overall length, the Dexter DX7.5L A-60 keeps installation clean and compact while delivering smooth, controlled braking every time you tow.

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
My package arrived a day early.
Installed new actuator on my boat trailer in about 5 minutes bleed the system and brakes and it works like a charm.
The product is exactly what I ordered and it was shipped quickly. Only problem is it is missing the upper cap to cover the brake fluid reservoir. I did call Customer Service and they said they would send one ASAP. The photo online shows it is included with the product. I’m waiting on receiving it.
Great shipping time but parts missing from order I did call and they said they would ship them right out
The product you sent me had the correct internal parts that I needed although the mount was not correct I used my mount that came with the trailer.

Works great
The actuator came promptly. I replaced the old one with this one. It has been working great. I highly recommend this product
I received the actuator. It looks good so far! I plan to install soon. However, I did not receive the lockout metal tab pictured with the product.

Well shoot, sorry about that Kory. It looks like we have a replacement lockout key on the way and it should be delivered to you tomorrow (the 18th): 1Z6VV9470304771343 Let us know how the install goes when you get to it! And also, what are you installing it on?
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.
Great replacement for a damaged actuator. A plan came together and it don't get much better.

Over 2,000 miles and the actuator is working great. Enough said.
Great quality, fast shipping, and wouldn’t hesitate at all to purchase actuator again!
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.

Youre so welcome! Thanks for coming back to leave a review - it certainly means a lot to us!
Love the updates.
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.
Fast delivery,no shipping damage! Direct replacement for my Magictilt boat trailer.

It has been over a year now and everything is working flawlessly. I am constantly in salt water with my trainer and there are no real signs of corrosion.

Prodcut is great... and Etrailer you have the best service. Awesome !
Ordering process went smoothly and Rachel actually found the product I needed even though a typical 'search' did not. Product was shipped / delivered within the time frame designated and looks good. Have not installed it as of this writing but appears to be exactly what I needed.
Easy replacement! Great communication & service!
Perfect for my Ranger Z521C bass boat trsiler. The outer sleeve assembly was not needed,
Awesome product and super quick shipping! Highly recommended!!!
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 !

Excellent ! This coupler is so easy to hitch and unhitch works great on my Ez loader boat trailer loaded with my 21’ North River Scout fishing boat
Great brake actuator, has everything you need and fits great. My old actuator had rings for the safety chains, this one does not. Just mounted my chains behind the actuator to the trailer frame. Good to go!
Had to replace a 6 year old A60 on a Magic Tilt trailer that was rusted and non functioning. etrailer was the go to for this replacement part. They had the right part and free shipping made this bolt on replacement flawless. From now on, I’ll keep it well maintained to keep it from rusting out.
Do you have a question about this Brake Actuator?
