Use this corrosion-resistant 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 drum brake applications.


Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • 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
  • Zinc plating offers excellent corrosion resistance
  • Bolt-on installation
  • Manual lockout kit and fill cap are included
  • Made in the USA


Specs:

  • Application: hydraulic drum brakes
  • Ball size: 2"
  • Fits 3" wide trailer tongues
    • Mounting holes positioned 3/4" down
  • 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.

Worked perfect rebuilding a 1990 boat trailer with drum brakes. The updated coupler is so much easier to use. Bolted on and brake lines conntected with no modifications.



by:

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



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:

This was an easy replacement and has worked very well



by:

Perfect fit. I had to notch one corner where my wiring came out of the box tubing. Really nice compared to the original that was on there



by:

Knowledgeable, friendly, helpfull, great follow up.



by:

This is a very well made Brake Actuator, with high quality and heavy duty materials. Flat top design suits my requirements of opening the tail gate without worrying about damaging the tailgate and for fixing the sticker for Ford Pro-Trailer Back up Assist. Overall, I am pretty happy with the product, pricing and prompt shipping.

However, I have two observations to make:
1. Manual lockout plate could have been tethered to receiver. Even better, fitted with a magnet so that plate does not fall off, when you are moving the trailer back and forth. There are after market products available with magnet. I improvised on my own with a piece of strong magnet from old hard drive.
2. I bought Dexter A-60 bolt-on top mount for two different trailers. I observed that in both cases, the mounting holes in the receiver does not exactly line up with holes in trailer tongue- off by about 1/16th of an inch. Looks like the inner unit welding to outer case could be the cause.

So I would rate the product as 4.5/5.

  • Replacement Hydraulic Brake Actuator for Homemade Trailer With Short Tongue
    I'm assuming you have hydraulic drum brakes and actually need the brake actuator. If that is the case, you're looking at either extending the tongue so you can bolt on an actuator like the # DX33FR or welding one on like the # DEX94FR. Both have a 7,500 lb capacity and are compatible with drum brakes. If it were me, I would stick with the bolt on option and get a local trailer shop to extend the tongue a bit. This would also make for an easier swap in the future should you need to replace...

  • Replacement Hydraulic Drum Brakes, Hub/Drum, and A-60 Actuator for 3,500 lb Axles on Boat Trailer
    We have exactly what you're needing! For replacing your hub/drum assemblies you need the kit # AKHD-545-35-EZ-K (2 per axle) and then for the brakes you need the kit # AKFBBRK-35-D (1 per axle). The actuator is a little different simply because there are multiple styles for installing the actuator on your trailer coupler so you'll want to look through these options to see which A-60 best matches your current A-60 actuator: - Top Mount 3-Bolt # 099-175-00 - Top Mount 3-Bolt # DX33FR ...

  • Actuator Solution that Can Fit 4 inch Wide Tongue
    You could weld an actuator like the Dexter Drum Brake Actuator part # T1607500 to the top of your trailer tongue but there isn't one that fits around a 4 inch wide tongue. If your brakes are disc instead you'd want the part # T4749600.

  • Replacement Drum Brake Actuator For UFP Model A-70
    To replace your old UFP A-70 actuator I recommend using the Dexter DX7.5L A-60 Brake Actuator - Bolt On - Drum - 2" Ball - Zinc - 7,500 lbs # DX33FR. This is going to be a direct replacement and will work with your drum brakes.

  • Recommended Weld-On Replacement For An Atwood 82541 Surge Brake Actuator
    Hi Doug, If the tongue really is C-Channel and not a box the you'd likely need to first weld a piece of metal to fill in the gap on the open end for the new actuator to weld onto. You could go with an actuator like the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX63FR. You'd weld this to the top of the channel, but there aren't welding instructions included. This actuator has a 7,500lb capacity, fits a 2" hitch ball, and comes with an electric reverse lockout solenoid so...

  • Does the Dexter DX7.5L A-60 Brake Actuator Have a Lockout
    The Dexter DX7.5L A-60 Brake Actuator part # DX33FR comes with a manual lockout key for reversing. That said, if you would like for this to be done automatically you can simply add an electric lockout, the Solenoid Valve part # T4748800. That said, you'll also need a 5-way on the trailer and vehicle for this so if you don't already have one I recommend the Hopkins Endurance 5-Way Flat Trailer Wiring Kit part # HM47890. The Dexter DX7.5L A-60 Brake Actuator is made in the USA.

  • Recommended Surge Brake Actuator for a 3" x 5" Tongue
    Thanks for the pictures! It looks like you have a 3" x 5" channel so the Dexter DX7.5L A-60 Brake Actuator item # DX33FR will work for you. You will need to measure the width of the top of your channel to confirm this will fit.

  • Replacement Brake Actuating Coupler for Atwood 85778
    The Atwood 85778 actuator has been discontinued so I recommend the Dexter DX7.5L A-60 Brake Actuator - Bolt On - Drum - 2" Ball - Zinc - 7,500 lbs # DX33FR. If you need a higher capacity, then you will need to use a 2-5/16 inch hitch ball. I've linked the page to other options if needed.

  • Picking Out Replacement Actuator for UFP A-60
    The Dexter DX7.5L A-60 Brake Actuator part # DX89FR for disc or part # DX33FR for drum will work to replace both a UFP A-60 or A-75 Brake Actuator. The A-60 is rated for 6K and the A-75 is rated for 7.5K. The Dexter DX7.5L A-60 Brake Actuator is rated for 7.5K.

  • Can Dexter Drum Actuator have Electric Reverse Lock Out Added It
    Dexter doesn't put reverse lock outs on their drum brake actuators so you'd need to add the part # DM5404 do a new actuator. The part # DX97FR is just the inner section of an actuator though. For the actuator you'd need the part # DX33FR.

  • Replacement Inner Member for UFP A-60 Drum Brake Actuator
    Thanks so much for the photo, which shows you have a UFP A-60 actuator, which is the same as the Dexter DX7.5L A-60 Brake Actuator - Drum # DX33FR. I can confirm that the correct replacement inner member for both actuators is the Replacement Inner Member # DX97FR.

  • Replacement Trailer Coupler Recommendation for an Atwood 87558
    Instead of using the Demco Hydraulic Brake Actuator # DM72VR I recommend using the Dexter DX7.5L A-60 Brake Actuator # DX33FR. I went out to our warehouse and confirmed this coupler has a 3-7/16" max width which looks to be exactly what you need for your trailer.

  • Is There a Dexter DX7.5L A-60 Brake Actuator Primed That is Bolt On
    There is not because the Dexter DX7.5L A-60 Brake Actuator - Primed # DEX94FR is a weld-on actuator, and those are the only ones that are primed to be painted. Bolt-on actuators do come with zinc plating and are not primed for being painted, including the Dexter DX7.5L A-60 Brake Actuator - Bolt On - Drum - 2" Ball - Zinc - 7,500 lbs # DX33FR.

  • Recommended Bolt on Brake Actuator for a Drum Brake 7,500 lbs Trailer
    I would be happy to help you. The Dexter DX7.5L A-60 Brake Actuator item # DX33FR you were looking at will work with trailers weighing up to 7,500 lbs. It requires a 2" ball and fits a straight 3" wide trailer tongue. It works best with drum brakes and has a manual lockout so you can back up without the brakes engaging. This hydraulic actuator will activate your trailer's brakes when your tow vehicle slows or stops. It has a bolt on installation and mounts on top of the trailer tongue...

  • Recommended Replacement For A UFP Model A-70 Brake Actuator
    Hi Charles, While we don't currently offer the inner member that you're needing for the UFP A-70 we do offer a compatible replacement with the Dexter DX7.5L A-60 Brake Actuator # DX33FR. This is the entire actuator assembly along with the mounting sleeve. If you have an electric lockout out to back up without having to manually lockout the actuator then I recommend picking up the Solenoid Valve # T4748800 as well.

    A replacement coupler option that is very similar to the existing coupler on your EZ Loader Trailer is the Dexter DX7.5L A-60, Drum, 2 Inch Ball Brake Actuator # DX33FR. Dexter acquired UFP, so actuator is essentially an updated version of your existing actuator. This actuator has a capacity of 7,500 lbs, like your existing coupler.

  • Correct Replacement for UFP A-60 or A-75 Brake Actuator
    The Dexter DX7.5L A-60 Brake Actuator part # DX89FR for disc or part # DX33FR for drum will work to replace both a UFP A-60 or A-75 Brake Actuator so there will be no worried here.

  • Can Dexter DX7.5L A-60 Actuator DX56FR Replace Older Titan Aero 6000?
    As long as your trailer has a 3" x 5" trailer tongue then the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX56FR will replace your Titan Aero 6000 Coupler. Keep in mind this actuator is designed for disc brakes, so if you have drum brakes this will not work for you. If your trailer has drum brakes you will need the # DX33FR instead. I included videos of the products mentioned for you to take a look at.

  • Replacement Straight Tongue Actuator Recommendation for 2003 Ranger Boat Trailer
    It looks like your 2003 Ranger 521 boat trailer has a straight tongue coupler so you should be able to use something like the Dexter DX7.5L A-60 Brake Actuator # DX33FR. This is a bolt on application that fits a 2" hitch ball and has a weight capacity of 7,500 lbs. The bolt holes sit down 3/4" from the top of the trailer tongue and then they are 3" apart on center. If you have an actuator with different specs let me know what those are and I can see if we have something that works for you.

    The Dexter DX7.5L A-60 Brake Actuator part # DX89FR for disc or part # DX33FR for drum will work to replace the surge coupler of your Mastercraft boat trailer. I looked up your trailer and was not able to determine if it had disc or drum brakes which is why I listed both options.

  • Replacement For TDE LP7000 Surge Brake Actuator
    There isn't a rebuild kit, but you can definitely replace your TDE LP7000 brake actuator with one of the following, depending on if you have disc or drum brakes: - Drum Brakes: Dexter DX7.5L A-60 Brake Actuator # DX33FR - Disc Brakes: Dexter DX7.5L A-60 Brake Actuator # DX89FR These are both 7,500 lb actuators that accept a 2" hitch ball and bolt onto a 3" wide trailer tongue.

  • Is The Outer Shell Of The Dexter A-60 Surge Coupler Available Separately?
    The outer shell for the Dexter DX7.5L A-60 Brake Actuator # DX33FR is only available with the entire actuator. They do offer the Replacement Inner Member # DX97FR for this particular actuator since those parts are more likely to wear and become damaged than the outer shell.
