Dimensions between mounting holes

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.

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 !

Thats awesome, Matthew, thanks. Were you able to get out on the water much this summer?

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.

Exactly what I needed. Fit perfectly and easy to install.

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.

I received my order two days ago, Quick shipping but it was the wrong part. I called and spoke with Noah who sent me an email asking me to take a picture of the part and add my phone number. I did right a way and still have not heard back. I emailed Noah today asking about the status no reply, now Im on a 9min hold to try and talk with someone about my replacement past. The wrong part looks like a good part if it fit my trailer.

  • Could Dexter A-60 Coupler Fit 2005 Four Winds Trailer
    If you have a coupler actuator that looks like the # DX29FR but it mounts inside the channel on the trailer frame what you would most likely actually want is the inner member of this coupler with the part # DX99FR. This is the inner section of the Dexter actuator which it sounds like you have the outer section welded to your trailer frame.

  • Replacement For TDE LP75 Disc Brake Actuator
    We can get you a replacement for your TDE LP75 disc brake actuator; that's a 7,500 lb actuator that accepts a 2" hitch ball, and the correct option will depend on if your trailer tongue is 3" wide x 4" tall or 3" wide x 5" tall: - 3" x 4": Dexter DX7.5L A-60 Brake Actuator # DX29FR - 3" x 5": Dexter DX7.5L A-60 Brake Actuator # DX56FR As for your second question, both do have the electric lockout, as there isn't an option for the old school type you were referencing.

  • What Kind Of Plug Do I Need In Order To Use The DX29FR Surge Brake Actuator
    The Dexter Surge Brake Actuator # DX29FR features an electric lockout. The surge brake actuator itself does not need to be plugged in to anything for it to work. The electric lockout does need to be wired if you want to be able to back up without locking up the brakes. The blue wire goes to your vehicles reverse light circuit, the white wire is a ground. This allows you to back the trailer up without actuating the brakes. Generally trailers with a surge brake actuator and electric lockout...

  • Recommended Drum to Disc Brake Kit for a 3500 lb Tandem Axle Boat Trailer
    Mark, the Kodiak Disc Brake Kit # K2HR35DKG appears to be what you're looking for but you're going to need to verify which bearings your trailer uses right now to make sure it's compatible. The bearings, actuator # DX29FR and brake lines # 18TA-BLKIT would need to be added separately as well.

    We have the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX29FR for disc brakes and the Dexter DX7.5L A-60 Brake Actuator # DX27FR for drum brakes. These will have similar bolt patterns as the Tie Down Engineering LP7000 actuators we have have seen in the past. They are designed to fit a 3" wide by 4" tall trailer tongue. If you have a different size trailer tongue please let me know so I can recommend a better option since I have seen this particular actuator mounted differently.

  • Disc Surge Brake Actuator Replacement for a Titan Aero 7500
    I recommend using the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX29FR to replace the Titan Aero 7500 you currently have. The top holes are 3" apart on center which should match with what you currently have, but you'll need to drill new holes for the bottom bolts. It doesn't look like there are any actuators with the exact bolt pattern you have which is why I recommend this actuator. Attached is an installation video for you to check out.

    I would be happy to help! Starting with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc # DX29FR this will fit the 3" x 3" tongue of your 2003 Magic Tilt Trailer perfectly, and is a fantastic option due to it already including an electric lockout solenoid for the backing up the trailer. The Kodiak Disc Brake Assembly # K1HR35D you were looking at will fit your 3500lb axles perfectly, but I do recommend adding these kits to both axles of your trailer. Adding them...

  • Is Dexter DX7.5L DX29FR Designed To Mount Inside Of 3" x 4" Trailer Tongue?
    Yep! The Dexter DX7.5L # DX29FR is indeed designed to fit inside a 3" x 4" tongue as long as you have disc brakes on your trailer, though it is a bit of a different design than your old TDE LP7000. I included a video where Ryan installs it like that. If you can modify your tongue to make this work, Great! If you're not comfortable with making it work, then a coupler that bolts over your tongue like the # 099-175-20 is going to be a better option due to being a bit easier to install.

  • What Size and Grade Mounting Hardware for the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout
    The Dexter DX7.5L A-60 Brake Actuator w Electric Lockout part # DX29FR for disc brakes and part # DX27FR for drum brakes use 1/2" diameter mounting hardware. We have used both grade 5 and grade 8 bolts when doing installations of them but the grade 5 are sufficient. There is very little force actually applied to the bolts other than side pull.

  • Replacement Surge Actuator for Reliable ACT 7.5K Actuator
    Best solution we have would be the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc # DX29FR which will fit over the 3 inch by 5 inch frame channel you have. This is a very similar design to what you have now and has the same weight capacity so it would work well. This is the disc brake version so if you have drum brakes instead you'd want the part # DX27FR.

It can be slid inside a trailer tongue or it can be placed over the tongue, like for your application. It has the electric lockout, 7.5K capacity and 2" ball coupler that you are looking for.

  • What is Difference Between Dexter Couplers # DX29FR and # DX56FR

The part # DX29FR is designed to fit a 3 inch by 4 inch straight tongue whereas the part # DX56FR is designed to fit a 3 inch by 5 inch straight tongue. Aside from that they are both 7,500 lb trailer coupler actuators with a 7,500 lb capacity designed for 2 inch hitch balls.

  • Replacement Surge Brake Actuator For Trailer W/ Older Swing Away Actuator For Disc Brakes
    Thank you for the pictures! For a replacement option I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc - 2" Ball - Zinc - 7.5K # DX29FR to replace your current actuator. The # DX29FR has a 7500lb trailer weight rating, is designed for trailers with disc brakes, and is a bolt on replacement. You will likely also need a replacement swing away tongue adapter like the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue # FHDPB340301 which fits 3" x 4"...
