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.


Features:

  • Activates your trailer's disc brakes when your tow vehicle slows or stops - no brake controller needed
  • Lets you back up without locking up your trailer brakes
    • Electric reverse lockout keeps your trailer brakes from activating when your reverse lights come on
    • Included pin lets you manually lock out the brakes if you tow with a truck that only has a 4-way
  • Creates a sleek look with its low-profile design
    • Coupler latch sits flush with the actuator's body
  • Provides you with a reliable, secure connection
    • Latch mechanism only engages when the hitch ball is fully seated
    • Safety pin keeps the socket closed around the ball, even if the latch pops up
  • Resists rust and corrosion
    • Zinc plating is great for boat trailers
    • Aluminum master cylinder is rustproof, unlike cast steel ones
  • Includes breakaway cable with S-hook
  • Bolts onto your trailer tongue
    • Hardware not included
  • Certified by the SAE for safe, reliable operation
  • Made in the USA


Specs:

  • Application: trailers with hydraulic disc brakes
  • Designed to bolt on top of a 3" wide x 5" tall trailer tongue
  • Ball size: 2"
  • Gross towing weight: 7,500 lbs
  • Dimensions: 19" long x 5-3/16" tall
  • 2-Year limited warranty


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.


Simple, Secure Connection

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


A close-up view of a mechanical latch in the closed position on a Dexter trailer brake actuator A close-up view of a mechanical latch in the open position on a Dexter trailer brake actuator

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.


Demo of the button and latch on the Dexter DX7.5l A-60 brake actuator UFP by Dexter brake actuator with the latch open and safety pin removed

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.


Electric Reverse Lockout with a Backup Manual One

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 back of the brake actuator reveals the electric solenoid that engages the electric lockout Two wires that connect to the electric solenoid on the A-60 UFP brake actuator

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:

  • Lake water shorts out the solenoid
  • Critters chew up the solenoid's wires while your boat is in storage for the winter
  • You take your boat to the lake with a vehicle that only has a 4-way
  • Some other wiring issue comes up

A demonstration of how to use the manual lockout on the UFP by Dexter A-60 brake actuator A demonstration of what the manual lockout pin looks like when it's left in the UFP by Dexter A-60 brake actuator

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.


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.

  • Where to Find Surge Brake Actuator Information on Trailer
    Your surge coupler will have either a sticker or an engraving on it, typically near where the coupler is located. If you can get me that information and what you're needing to replace on it I'd be more than happy to help you find what you're needing! For an example, the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX56FR has this info engraved on the top of the actuator body (see attached).

    That's a really good question, and there is a difference between the 7,500 lb Dexter DX7.5L A-60 actuators for disc brakes; the differences are both in what they fit, as well as their length. - 14" Long & Top-Mounted For 3" Wide Trailer Tongue: Dexter DX7.5L A-60 Brake Actuator # DX89FR - 19" Long & Bolts To 3" x 4" Trailer Tongue: Dexter DX7.5L A-60 Brake Actuator # DX29FR - 19" Long & Bolts To 3" x 5" Trailer Tongue: Dexter DX7.5L A-60 Brake Actuator # DX56FR Apart from that, these...

  • What Surge Brake Actuator do I Need for My 2009 Ranger Boat Trailer Replacing UFP A-60?
    Hey Mickey, We definitely have an surge brake actuator that is going to work for you. I do not have a database that supplies me with what is put on what trailer, in my research I found that most 2009 Rangers have the TDE LP75 which makes sense because that is what I have on my 2004 Ranger Comanche. I am showing that you have a 3 x 5 trailer tongue, but just in case there is the 3 x 4 as well: - 3" x 5": Dexter DX7.5L A-60 Brake Actuator # DX56FR - 3" x 4": Dexter DX7.5L A-60 Brake Actuator...

  • Replacement Disc Brakes and Actuator for Magnum Boat Trailer
    Hey Michael! It sounds like that is a UFP H-1377 which would be a 3,500 lb hub using the standard bearing combination. I'm guessing you have slip on rotors based on that information. If you want to use the existing hubs the DeeMaxx Disc Brake Kit # DE42FR is the best option. If you want to go ahead and replace everything I recommend the Kodiak Disc Brakes # KOD87FR which cost a little bit more. Disc brakes are always on the higher end, these are the most budget friendly available. I don't...

  • Recommended Coupler Lock for a Dexter DX7.5L A-60 Brake Actuator
    Hey Javier. To secure your Dexter DX7.5L A-60 Brake Actuator item # DX56FR, I recommend our etrailer Surge Brake Coupler Lock item # e98888. This will allow you to lock the coupler to the ball. It will also secure your coupler so no one else can connect their vehicle to it and drive away. I attached a picture below that will show you how the item # e98888 attaches. You'll want to make sure your brake actuator has that hole if you don't have the Dexter item # DX56FR. Do you see any part...

  • Help With Verifying Torsion Axle Angle Being Different From One Side Of Trailer To Other
    You could be experiencing one of 2 separate issues or a combination of both. If the side at 38 degrees is the passenger side I have seen this a lot as that side of the trailer typically experiences the worst ride quality from damage to the edge of the road. It could either be the rubber torsion inserts inside the axle are worn and allows it to sit lower. You can verify this is the issue if the end of the spindle can easily be raised higher. You could also have a bent axle where the spindle...

  • My Surge Brakes Are Activating When I Back Up My Trailer - What Can I Do?
    Hello Gregg, I think I can help shed some light on what is going on. Basically, there are two ways to stop surge brakes from actuating when backing up the trailer. The first and most popular way to do this is to use a surge brake actuator with a reverse lockout. For example, the Dexter DX7.5L A-60 Brake Actuator # DX56FR has an electric lockout. The solenoid is wired to the reverse light circuit on the tow vehicle. This way when the vehicle is put in reverse, the actuator will be locked...

  • Why Would Dexter Actuator Be Tight on Hitch Ball
    Was it always a tight fit or did it get tighter over time? It's not adjustable so I'm curious if maybe the ball portion of the coupler has dirt or something built up in it that is making it a tight fit.

  • Can I Add Brakes To A Vintage 1962 Tandem Axle Boat Trailer
    Hello Alan, it may be possible to add brakes to your trailer. Since it will be in the water, adding hydraulic drum brakes will be the best option. First you will need to make sure your axle has a brake flange welded to the base of the spindle. If no brake flange is present, they can be welded on, or you can replace the axle entirely. If you do have a brake flange, brake assemblies can be bolted up. I will need to know your axle weight capacity, as well as the inner bearing size, outer...

    Hey Mel thanks for the picture! I really like your idea and if you go forward with it, send me a video!

  • What Dust Cover and Break Away Cable do I Need for My A-60 Surge Brake Actuator?
    Hello Mike, For your A-60 surge brake actuator like the # DX56FR, you’ll want the Emergency Breakaway Cable Repair Kit for Dexter A-60 Brake Actuators # DX64XR to replace the cable. For the cover, the correct part is the Replacement Black Plastic Filler Cap for Dexter 7,500 lb Brake Actuators # T097-022-00. Did the cable break in an emergency situation? And what kind of boat do you have riding on that trailer?

  • Best Replacement For TDE Disc Brake Actuator F47260K
    Hello Jeremy, thanks for reaching out. The part number F47260K comes back as the master cylinder for a TDE model 66, 70 and 80 disc brake actuator. It sounds like yours may be the model 70, and if so, the Dexter # DX56FR can be used to replace it. This is designed to bolt onto the end of the tongue. If you need one that drops onto the top of the tongue I recommend the Demco # DM62VR instead. Both are rated for use with disc brakes and have a max capacity of 7,500 lbs.

  • Help With Installing Dexter DX7.5L A-60 Brake Actuator On Boat Trailer
    The Dexter DX7.5L A-60 Actuator # DX56FR you have is designed to be mounted on the end of the trailer frame as seen in the image below.

  • How to bleed the brakes on a surge brake actuator on boat trailer
    When bleeding the brakes on a surge actuator, such as the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX56FR, you want to start by making sure there is fresh fluid in the reservoir then press a screw driver against the rod in the access hole to pump the brakes. If you don't have an access hole, wrap the safety chains around a pole or board and push the top into the coupler to force the pumping action that way. I attached a detailed write-up page that explains this process, and...

  • Replacement for Dexter A-60 Brake Actuator
    Hi Joshua; you can respond to the email that had the link for this page if you want to send me the video. It does sound like it is the actuator, could be the shock in there or the master cylinder. It would also be worth checking to see if the brake fluid is low. For a replacement you can use the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX83FR for drum or # DX56FR for disc brakes. Both are designed for a 3" x 5" tongue.

  • Replacement Brake Actuator for ShoreLand'r Boat Trailer
    Hi Chris; we don't have a way of knowing what parts are on your trailer using the VIN. The Dexter DX7.5L A-60 Brake Actuator # DX56FR is designed for a 3" x 5" tongue and disc brakes. If you have drum brakes you need the # DX83FR instead. If you have a different size trailer tongue let me know and I can see what else is available. Did something happen to the brake actuator that came with the trailer? It looks like it is a 2024 model so most parts should be in good shape.

    No, I am sorry Carey they do not make an adapter for an actuator like the Dexter DX7.5L A-60 item # DX56FR that spins. You'll have to remove your brake line, install it on the actuator, and then reconnect your brake line to get it connected. How long is that brake line? If you want to replace that brake line with a fitting that spins, I would just need to know how long it is.

This uses the Replacement Inner Member # DX99FR but for whatever reason the inner member itself costs more than the complete assembly. Might as well save some money and remove the housing, it is the same part inside. Any big trips coming up with your boat this spring?
