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 disc brake applications.


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
  • Zinc plating offers excellent corrosion resistance
  • Bolt-on installation
  • Made in the USA


Specs:

  • Application: hydraulic disc brakes
  • Ball size: 2"
  • Fits 3" wide trailer tongues
    • Mounting holes positioned 3/4" down
    • Mounting holes spacing (center on center): 3"
  • 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.

E trailer is the best. I have bought dozens of items from them an it was always a great experience. Customer service is the best.



by:

Wow, my order showed up within days and I’m very impressed. I have not installed the coupler yet but looks like a quality product. Thank you!



by:

Item was great. Information was completely helpful to install. Great customer service and support.



by:

Exact replacement for my 2013 ezloader and a upgrade



by:

Paid 115 for next day shipping, obviously it was very important. They never sent me a tracking and made excuses....not sure why it was a secret



by:

Customer service was very helpful. Speedy shipping.



by:

Poor packed and arrived bent. Had to straighten metal in order to fit.



by:

The product came unboxed, missing instructions and no spare break away clips. I purchased a new actuator and got one that was laying around.



by:

The manual lockout device, supplied with the actuator, requires a second person to hold it in place when backing. It will not stay in place on its own.



by:

This product doesn’t fit over 3” tongue. Its the exact same size as a 3” tongue.Unusable. Had to remove the internal portion and modify my trailer tongue to fit. Arrived as the worst packaged item I’ve ever received. It was barely still in the box. Whom ever packaged this didn’t have a clue what they were doing.



by:

I'm very pleased with the product, installation was a breeze.



by:

Very sturdy material and well made. Works as designed and the electrical lock out for disc brakes is very useful.

Manual lock out lever key could be magnetized to avoid falling off.



by:

Ordered brake actuator from Etrailer after several attempts from EZTrailee with no response. Wished I had checked out Etrailer sooner. Received notification at each billing, shipping.
It was easy to find the parts got fast shipping with working brakes now, can enjoy the boat again. This is the third trailer you helped me repair with correct parts, fast shipping
Many thanks guys



by:

Kim was great and answered all my question and the Actuator came way quicker that expected and the shipping was free!



by:

Missing one tiny part but they will make it right . Faster shipping than expected was a good treat ! I would buy again when needed .



by:

Item came on time and was packaged well and the price was reasonable. Will buy from ETrailer again.



by:

Part was easy to install and works as advertised
Thank you Demi for assisting me, to make sure I have the correct Part for my application.

by:

Great service. I received exactly the part that I needed ready to be installed, and on time. Thank you everyone from trailer.com.



by:

The product is as expected and an exact replacement for my trailer. The exceptional part of the transaction was the speed my order was filled and shipped.



by:

Awesome actuator and works great with the brakes and line kits I ordered!



by:

etrailer will get all of my business in the future. Had trouble ordering online with my card. Called customer service and the lady I talked with went way beyond helping me out. Was super friendly and very knowledgeable. My order was pack and picked up by UPS three hours later. It arrived on time and was exactly what I ordered. Thanks etrailer and customer service lady for great experience!

You're so welcome, Kevin. I'm glad we could help!



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:

Product was exact fit for the 4 star review would have been five except the tongue cover was busted from shipping. Otherwise great.

  • Option For Replacing Swing-Away Actuator On A 2005 Mastercraft Boat Trailer
    We do have a potential solution for you. Unfortunately, the swing away actuators like the one on your 2005 Mastercraft trailer have been discontinued, so I am afraid there is no direct replacement, or anything that will fit inside the current swing away. At this point we would have to recommend replacing the tongue of the trailer entirely, all the way down to the swing away. For a replacement option I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR. This has...

  • Difference Between Dexter DX7.5L A-60 Brake Actuators For Disc Brakes
    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...

  • Replacing TDE 70LP On Swing Away Tongue
    Hi Jeong-Won; the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR fits a 3" wide trailer tongue without a specific height requirement. To add a hinge back onto the tongue you simply have to measure the height. If you have a 3" x 4" trailer tongue you can use the SwingKing # TD53FR (galvanized) or # TD33FR (black powder coat). If you have a 3" x 5" tongue then # TD93FR (galvanized) or # TD43FR (black). If that was the old integrated design I would expect to have to buy some...

  • Replacement Brake Actuator for a 2013 Ranger Bass Boat Trailer
    Hey Mark, welcome back! If your 2013 Ranger Bass Boat Trailer has a UFP Model A-60 Marine Surge Brake Actuator similar to item # DX89FR, you can replace it with the Inner Member for Dexter DX7.5L Actuator item # DX99FR, you were looking at. The Inner Member item # DX99FR will install inside the housing that's already attached to your trailer's coupler. This actuator works with disk brakes. If you have drums you'll need item # DX97FR. If you could get me a part number off of your trailer's...

  • Marine Grade Surge Brake Kit Recommendation for a 16' Boat Trailer
    Hey Stephen, thanks for reaching out! I believe you have a 3,500 lb axle so I'm going to base my recommendations off of that, but it would be best if you verify this on your own. You can see the axle rating either on the tag near the tongue of your trailer or on the tag in the middle of the axle itself. We have some drum brakes with a dacromet finish, but there aren't any hub/drums with a marine coating so I recommend going with some disc brakes; specifically the DeeMaxx Disc Brake Kit...

  • How Do I Hook Up the 2 Wires on My Dexter DX7.5L A-60 Brake Actuator w Electric Lockout?
    Hello Mike, Your old brake actuator only had one wire because it grounded through the trailer frame, which was pretty common back in the day. Your new Dexter DX7.5L actuator # DX89FR has two wires coming off the electric lockout solenoid no worries, it’s super simple to hook up. The blue wire connects to your reverse light circuit (usually the center pin on a 7-way plug), and the white wire just needs to go to a good ground on your trailer frame. That way, when you shift into reverse,...

  • Is There a Replacement for the Tie Down LP80 Brake Actuator?
    Hi Syo, There is not an exact replacement that will slide into place to replace your Tie Down LP80 because it has been discontinued, so you would have to go with a completely new actuator. It looks like the Tie Down LP fits a 3" wide channel tongue, if that's the case for your trailer, you can use something like the Dexter DX7.5L A-60 Brake Actuator w/Electric Lockout part # DX89FR. It bolts-on to 3" wide trailer tongues and its mounting holes are spaced 3" apart center to center so you...

  • Difference Between DX99FR and DX89FR
    Hey Dan! The only difference is that sleeve you referenced on the # DX89FR. The # DX99FR is actually part of the # DX89FR and acts as a replacement inner member. Are you asking because of the difference in cost? I'm not sure what our pricing model is thinking right now but I would get the # DX89FR and pull out the inner member to save some money if that is all you need.

  • Amp Draw on Dexter DX7.5L A-60 Reverse Lockout Solenoid
    Hey Rick! The reverse lockout solenoid on the Dexter DX7.5L A-60 # DX89FR and others like it uses less than an amp. To be a little more precise, you can expect it to be approximately 0.7A - 0.8A.

  • 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. Based on how your actuator was mounted the Actuator # DX89FR would best install like your current actuator. If you choose to continue with the actuator you have you will need to slide it onto the frame as seen in the image I attached and drill for all 4 holes.

  • Replacement For A Reliable ACT 7.5 KS Brake Actuator
    At this time we do not carry a compatible inner member for your Reliable ACT 7.5 KS actuator so I recommend replacing it with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR. This hydraulic actuator activates trailer's brakes when tow vehicle slows or stops and electric reverse lockout lets you back up without actuating trailer brakes.

  • Replacement for TDE LP85 Surge Brake Actuator
    Hi Chris; I believe the LP85 was integrated into the tongue of the trailer. Unfortunately, that means it won't be an easy swap to replace it since other actuators won't fit inside the trailer tongue and line up with the holes from your old actuator. The Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX93FR you looked at will work as a replacement as long as a 7,500 lb capacity is high enough for your trailer. This is designed for disc brakes which I believe you have since the LP85...

  • 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.

  • Comparing Dexter Surge Brake Actuators DX29FR And DX89FR
    Hello Jarrod, thanks for reaching out. The main difference between the Dexter # DX29FR and # DX89FR is how they attach to the trailer tongue. Each will fit a 3" wide tongue. The # DX29FR is designed to bolt onto the end of the tongue, whereas the # DX89FR is intended to sit on top of the tongue. Both use the same 3" bolt spacing, you will just want to pick whichever one installs the same as your current actuator. I have included a few pictures with examples below. I hope this helps, and...

  • Replacement Option For Tie Down 80LP Actuator For Disc Brakes
    Hey Dan; there isn't an actuator that will slide in place for a replacement of your Tie Down 80LP, you'd have to go with a new actuator. From what I can find, this actuator bolts onto a 3" wide channel tongue, so you can replace it with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR.

  • Replacement 2" Disc Brake Actuator for Dexter A60
    Hey Stephen! The Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR will work as a replacement for the A60 you have now. This is designed for a 2" ball, disc brakes, and fits a 3" wide trailer tongue. If it is just the master cylinder that is bad the # DX44FR you ordered is the correct replacement. What kind of trailer do you have?

  • Can The Dexter DX7.5 A-60 Brake Actuator Replace A UFP A-75 Brake Actuator
    Hey Mirko, The Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR can replace the UFP A-75 actuator. The square head on the coupler would give less clearance than the rounded coupler of the A-75 but it's such an insignificant difference that you shouldn't have any issues. The # DX89FR will come with an electric lockout to allow you to back up without having to purchase any additional components.

  • Coupler Lock Recommendation For Dexter DX7 Coupler
    Hello Bob, thanks for reaching out. We have a few option for locks that will fit the Dexter DX7 coupler. For a locking pin I recommend the etrailer Surge Brake Coupler Lock # e98888. This will allow you to lock the coupler to the ball. The picture below shows it installed on a similar Dexter surge brake coupler. If you are looking for a lock for while the trailer is in storage, I recommend the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33. We have confirmed that this will fit on the...

  • Parts Needed to Add Hydraulic Disc Brakes to Pontoon Boat Trailer
    Hi Adam; the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR you were looking at is a great option to pair with the # KOD87FR. This fits a 3" wide trailer tongue so you will need to make sure that is what you have. This will also require adding a 5-way to the trailer and your vehicle to use the electric lockout. On the vehicle side you can use the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat # C57187. If you already have a 7-way on your vehicle then you could...

Unfortunately, I do not have any replacement parts for a TDE Model LP7000 actuator so my recommendation is going to be to replace yours entirely with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout item # DX89FR.

  • Availability of a Coupler Repair Kit For a Reliable ACT-7.5K Brake Actuator
    Hey, Hunter. It looks like you have a Reliable ACT-7.5K surge brake actuator. We don't carry their products and from what I can find on various forums and groups online, there aren't any replacement parts available anymore. I know this isn't news you're wanting to hear, and I'm sorry that we don't have anything that will work for you. Each manufacturer made their latches slightly different, so there isn't a way to use one from another actuator on yours. If your latch is completely unusable,...

  • Switching An Electric Over Hydraulic Brake Set Up To Surge Brakes
    Hi Scott! You can do either! The brake controller option would be the way I would go though as you wouldn't have to bleed the brakes (which is a pain in the butt) and it can be used with other trailers that have electric or electric over hydraulic brakes (plus it works better than surge brakes). For that, you will only need a few things, but I wanted to ask a few things first. Are you sure it's a 6-pin plug? They aren't used very often, but will still work. I included a picture showing...
