Features to know about
Smooth Stops on Heavy Loads: Surge Design for Disc Brakes
This zinc-plated surge actuator keeps braking simple and controlled. It’s built for disc brake systems and synchronizes your trailer’s hydraulics with the tow vehicle’s brakes for steady, even pressure. With a 12,500 lb capacity and a maximum tongue weight of 1,250 lbs, it’s sized for serious loads without feeling sluggish or harsh. The unique roller design helps it telescope straight, reducing friction and keeping the motion smooth every time you brake.
Backing Up Made Easy: Electric Reverse Lockout
No more hopping out to pin the coupler or fighting locked-up brakes in reverse. The built-in electric lockout solenoid automatically disables braking when you shift into reverse through a 5-pole flat, 6-way round, or 7-pole wiring harness. It also has a protective shield that keeps the solenoid safe from road spray and grime so it stays reliable over time.
Corrosion Resistance That Lasts: Zinc-Plated Steel Housing
Trailers see plenty of weather, so the zinc plating is a big plus. It stands up to saltwater spray and general corrosion far better than raw steel, which makes it especially handy for boat and utility trailers. The sturdy steel body resists bending in tight turns or jackknife situations, giving you strength and protection where it counts.
Simple Bolt-On Fit: 3" Channel with Built-In Drop Coupler
Installing it is straightforward—it bolts right over a standard 3"-wide trailer tongue with no cutting or welding. The heavy-duty coupler has a built-in 3" drop and fits a 2-5/16" ball, which helps level your trailer and improve stability on the road. The included breakaway kit adds peace of mind by engaging your brakes automatically if the trailer ever disconnects while towing.

I purchased this to because i was replace the drum brakes with disk brakes. It is an excellent actuator (as are the brakes and brake lines). The one issue I have is the thin metal shield for the backup solenoid, it has sharp edges that can cut the insulation of a wire (like the one going to the solenoid) or a child's finger. This design is clearly an afterthought by someone who is incompetent. I bent part of the shield back on itself to minimize the chance of any damage to the wire. This could be easily remedied if the manufacture would add a 1/2" and roll the metal back on itself before bending it. I guess I should be happy that the shield is there at all. I would give it 5/5 if it was not for this stupid afterthought design

After a year of service this thing seems to work pretty good. We had a slightly different style actuator that this unit replaced, I believe the big holes lined up pretty good and the installation was straight forward. We definitely got a big boost in braking power from the other unit that was failing. Unit still looks good after a year of use.

Haven't towed with it yet. Loosely bolted to trailer frame. fit perfect. tin on back around solenoid was bent coming out of package but not huge deal. Won't know more until it gets some road use but so far so good.

I think some other customers also mentioned this in their reviews that the packaging for this product is WORST EVER. They just put this in a box and ship it. This very heavy and expensive item, etrailer should package, box and ship this properly to avoid damage. I haven't tested the product yet but packaging is the WORST I have ever seen.

Item could be packaged better, it did however arrive a day early. The only reason I did not give a five star review, the guard for the backup solenoid is very thin and was bent to the point of having to be removed to be straightened. I am not sure that it will be strong enough to protect the solenoid and brake line if stepped on.

Actually I am a little disappointed. In hindsight I'm not sure I received the hitch I was supposed to get. I spoke with a rep before ordering and discussed the weight of my boat 6500# and I recently noticed that hitch is rated for 6000# lbs. What model was the original order for? Also the clasp on latch is very clunky/stick and covers part of the lock hole. I had to grind it down to get lock to slide through.

I'm sure the product works fine, but it was too long for my available trailer mounting space. If etrailer would provide measurements along with their product information, it would have saved me the return fees and hassle. Also, packaging is terrible. It was thrown in a box with no packing, and arrived all dented up. Now I have to return it, hopefully without discussion on whose fault that is. Box arrived full of holes, and unit dinged and dented on the corners.

- Timbren Axle-Less Suspension System Compatibility with Aluminum I-Beam Trailer FrameThe Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Lift Spindle - Off-Road Tires - 3,500 lbs # ASR35HDS02 is compatible with I-beam frames and in tandem axle configuration. Due to the Aluminum frame, I recommend putting a thin rubber pad between the steel mount and the aluminum I-beam. The powder coat on the steel should keep the two dissimilar metals from galvanic corrosion, but a thin rubber pad would drastically increase this safety. Zinc plated hardware will work well with...

- Replacement Surge Brake Parts for 2004 5 Starr Boat TrailerIt sounds like you have a Demco Actuator to me like # DM8104002. We also have one with a 4 inch drop # DM8104311. Both are Hydraulic Brake Actuators that are rated at 12,500lbs.,has a 2-5/16 inch ball, and bear the DA10 model number. I was able to look up your boat trailer and the parts used between packages varied. I can help you pick out Rotors, Lines, Calipers, and Pads if you can provide me with more information about the current items on the trailer. I will need the number of...
view full answer... - Roller Orientation for Reassembly of Titan Model 10Yes there are only two rollers on the damper. The chamfered edge on the # DX46FR should be facing out. The assembly instructions suggest using dummy pins out of 3/4" diameter dowels and state, "Insert one of the wooden dowels into the edge of the top slot of the inner. Then slide the dowel through a rear roller with the chamfered edge out, then through the end of the damper, and finally through another rear roller with the chamfered edge out.

Your Titan Model 10 part number 3241639 surge actuator has been replaced with the Dexter Zinc-Plated Brake Actuator item # T4750620. Dexter bought out Titan in 2015 and rebranded some of their actuators like yours. The Dexter Zinc-Plated Brake Actuator item # T4750620 fits a 2-5/16" hitch ball and has a 12,500 lbs towing capacity. It's zinc plated and fits a 3" trailer tongue. This one is specifically designed for disc braking systems only now. If your...
view full answer... - Replacement Surge Coupler for Tie Down 125Hey David, I totally understand what you mean by not liking the actuators that sit up top but at this time that's the only kind still available as your Tie Down 125 is no longer made. So the best overall option is the Dexter part # T4750620. I know you don't care for the way it looks but this part of the trailer isn't generally one that is scrutinized for looks as often.
view full answer... - Do I Need To Use Pin To Keep Boat Trailer Latch From Popping Open On Dexter Surge Actuator?Good morning Brian! Yes, one of these RV Designer safety lock pins should work for your Dexter surge brake actuator, but you’ll want to match it by the width of the coupler latch area. And if you don't use a pin, there's a chance it could come unlatched which would be really dangerous! Both the RV Designer Safety Lock Pin # RD72GR and # RD22GR use a 1/4 inch diameter pin. The difference is the usable span: the # RD72GR has a 2-1/2 inch usable length, while the # RD22GR has a longer 3-1/2...

- What Is The Power Draw Of A Reverse Lockout SolenoidHello Ryan, good question. The power draw for the reverse lockout solenoids is minimal. For example, the Titan reverse lock out solenoid part # T4748800 only draws 8 watts so it doesn't really draw much.

For a new shock absorber you will want the Replacement Shock Absorber Spring Kit for Dexter Brake Actuators # TK71-758-00. For a new master cylinder it will depend on whether or not you have disc brakes, or drum brakes.

view full answer... - Replacement Surge Brake Actuator To Replace Tie Down Model 125 12,500LB Drop ActuatorI recommend the Dexter Zinc-Plated Model 10 Brake Actuator w/ Drop to replace your current Tie Down actuator. You will need either the Disc Brake Actuator # T4750620 or Drum Brake Actuator # T2478100. These both have a similar design as your current actuator with a drop coupler attaching to a 2-5/16" hitch ball. The Drum Brake Actuator # T2478100 does not include a Electric Reverse Lockout # T4748800 but you are able to add one if needed.
view full answer... - Replacing Master Cylinder in Titan Model 10 Actuator on Boat TrailerIf the master cylinder you need is the part # T2374600 that would indicate that you have a Model 10 actuator like the part # T4750620. Which normally this bolts to the trailer frame. The picture you submitted doesn't quite show the coupler so I can't really tell what's going on. But you should be able to unbolt the coupler from the trailer to access the master cylinder and replace it. The two lower bolt holes that I pointed out in the picture are what hold the master cylinder to the coupler.

- Solution for Manually Locking Out Brakes on Actuator With Electric LockoutIf you have an actuator like the Dexter # T4750620 you looked at, the only way to lockout the brakes is with the electric lockout. If you have a different model it is possible it has a spot for a key on the side like the # DX94FR which would work with an actuator like the # DX56FR. If you do not have this, there is still a solution for your problem. Although you can't manually lockout the actuator, you could add free-backing brakes to your trailer. These eliminate the need for the lockout...

If it is a bit tight you may need to get a pair of pliers down there to give you extra leverage, but be careful to not damage the cap. I included a video of the # T4750620 for you to take a look at.

The other option is to use the same actuator that does come with an electric lockout, the Titan Zinc-Plated Brake Actuator w/ Drop, Electric Lockout - Disc - 2-5/16" Ball - 12,500 lbs # T4750620.

- Parts to Replace Hydraulic Brake System on a 2004 Magic Tilt TrailerWe can definitely get you started with parts for your Magic Tilt Trailer, but we will need some additional information to complete your parts list. We can start with a coupler. Since your boat trailer will not exceed 10,260 lbs, I recommend looking at a coupler like the Titan Zinc-Plated Brake Actuator for Disc Brakes, # T4750620. This coupler has a 3 inch drop like the coupler you referenced, but it has a 12,500 lb weight capacity which is closer to the weight of your trailer. Using...

- Replacement Surge Brake Actuator (3241639) And Brake Lines For 1995 Loadmaster Boat Trailer Hey Rob, the replacement for your surge actuator 3241639 is Dexter Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - 2-5/16" Ball - 12,500 lbs # T4750820, or if you need a drop coupler then use the Dexter Zinc-Plated Brake Actuator w/ Drop, Electric Lockout - Disc - 2-5/16" Ball # T4750620. They both have the electric reverse lockout you're looking for as well. For the brake line, the closest size we have is 26 feet and that would be Kodiak Hydraulic Brake Hose - 1/8" ID - DOT Approved...
view full answer... - Recommendation for Bleeding Hydraulic Brake Lines On Trailer Disc BrakesI recommend using the Hand Vacuum Pump Brake Bleeder # PTW87030 for bleeding the lines on your system with new actuator and calipers. This allows you to pull fluid through the lines and caliper to ensure there is no air and only fluid in the system. I use this system every time I bleed lines because it makes it easy for one person to do it.
view full answer... - Disc Brake Kit for a Grand Design Travel Trailer with 5,000 Pound Lippert AxlesYou likely have 5,200 pound de-rated axles. You can check the bearing numbers stamped into the sides of the bearings in one of the hubs on the trailer now to help determine what will fit. Most likely they use inner bearing 25580 and outer bearing 15123. For a disc brake kit that uses these bearings I recommend # K2HR526DKG. This is a kit for one axle so if you need brakes on both axles you would need 2 kits. For bearings you would need 4 of inner bearing # 25580, 4 of outer bearing...

The Titan Zinc-Plated Actuator part # T4750620 is a surge brake actuator so you need hydraulic brake lines. The kit you need depends on how long the trailer is that you are installing the lines in and how many axles the trailer has. The HydraStar Hydraulic Brake Line Kit part # HS496-252 is for a 25 foot tandem axle trailer. To install the lines you want to drill a hole near where the Titan Coupler installs so that you can...

The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup. This also needs to include the weight of any cargo behind the rear axle of the tow vehicle. Check out the link I attached that details how to determine tongue weight.
