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.

The reverse lockout can be engaged with a simple lever on the coupler. Once the lockout has been activated, you can back up your trailer without triggering the trailer brakes. Always remember to disengage the lockout mechanism when preparing to move forward.

Video Transcript for Titan Trailer Coupler T4839100 Review

Today we'll be reviewing part number T4839100. This is the Titan Arrow 7500 Swing-Away Actuator with a manual lockout. This is a bolt-on installation and it's designed to work with trailer disc brakes. It's going to fit a 2 inch hitch ball and it's rated at 7,500 pounds. One of the great advantages of having this is that the fold-away portion here, the swing-away design is actually going to allow you to save some space. To gain access to that we'd need to pull the pin and clip here on the back side. Then we can swing our coupler to the side of our trailer.

It would allow this portion to swing away. The fold-away portion can swing either right or left. You would just need to reverse the mounting bracket along with the hardware. We'll go ahead and reinstall our pin and clip. We have an overall length of 26 inches. Our pivot length which is measuring from the back of this upright cylinder to the end of our coupler measures 21 1/2 inches.

This hydraulic actuator is going to synchronize your trailer brakes with the tow vehicle brakes because when you apply the brakes in your vehicle, momentum actually pushes the trailer toward the rear of your vehicle. What the actuator does is it applies the force needed to the master cylinder which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes. We have a manual reverse lockout that lets you reverse without actuating your trailer's brakes. You can engage this with the simple lever here on the front of our coupler. Once this has been activated, you can easily back up your trailer without triggering the trailer brakes. In the upright position, it is activated.

When you want to move forward and just continue towing, you just put this lever in the down position. Always remember to disengage the lockout mechanism when preparing to move forward. This has a really nice zinc plating finish that's going to help it stand up against corrosion. The breakaway kit is included. The cable and hook would attach to the tow vehicle, and if for any reason your trailer would disconnect from your tow vehicle, it would pull this cable tight which would in turn activate the master cylinder to apply brake force to the trailer's brakes bringing it to an eventual stop. Here on top we have a cap that allows us to gain access to our brake fluid reservoir. You do want to be sure to bleed your brakes when you install.

That way we can ensure that both the right and left side brakes are working properly on our trailer. Here we have our pin that's attached to our coupler with a coated steel cable. That way it insures that we're not going to lose it or misplace it. It also allows us to lift up on our lever. That way we're ready to attach this to our 2 inch hitch ball. Now we'll go ahead and flip this over and we'll show you how a 2 inch hitch ball would attach to our coupler. It simply just fits right into place. Once it's in there, our lever here on top would close and we would reinstall our pin. To disengage, we lift up on the lever here on top and it drops the ball so we can disconnect the coupler away from our hitch ball. Also, here on the bottom you're going to see this little nib here. This is the connection point for the brake line of our trailer. We have our spring and our drum and our master cylinder. The mounting hardware is included. We have six bolts. Three of those are just regular hex bolt. The other three are carriage bolts. The carriage bolts will go on the bottom of the coupler unless this is reversed to swing out the other way. The regular bolts would go on top. We have a bolt hole diameter of 5/8 of an inch. Our hex bolt diameter is 3/4 of an inch. From the center of one mounting hole to the center of the other is an inch and 1/2. That's for the top and the bottom. I'll tilt this. That way you can see the pattern. It's just a standard triangle pattern. This is designed to fit a 3 by 5 wide channel tongue. We have 5 inches in height and 3 inches in width. If you have a 3 by 3 channel tongue, you can use to of the Titan adapter spacers. Those are available at part number T4842100 and are sold separately. If you have a 3 inch by 4 inch trailer tongue, you can use one of the Titan adapter spacer kits, part number T4842100 and that is also sold separately. This has a capacity of 7,500 pounds and a maximum tongue weight of 750 pounds. Again, it's going to fit a 2 inch hitch ball. It's designed to work with trailer disc brakes. I believe that's going to complete today's review of part number T4839100. This is the Titan Arrow 7500 Swing-Away Actuator. .

Review from a similar Titan Aero 7500 in Trailer Coupler


Morning Sorry for not getting back to you all sooner but I was out of town for sometime. Now for your product and company, let me say you are one of the few that I have done business with and I have to rate your complete service from start to finish as one if not the BEST I have done business with. In fact you are so good that I am going to recommend you to all the members of the Coastside Fishing Club. Thank you for your timely and excellent service. You are the best! --- George PS : If I was to add anything to this questioner it would be there were no instructions or spec's that accompanied the produce. Although your video of the product was excellent and even a dummy like me can make the install. --- Thanks Again 136362

Review from a similar Titan Aero 7500 in Trailer Coupler


The kit was fairly strait forward, but the included instructions are not complete. There was nothing for the installation of the hubs, rotors, bearings, or calipers. Customer service was able to email me some generic instructions that helped. etrailer's customer service is excellent, when I discovered some bolts missing from the box and had no time to wait for replacements to be shipped out Anna from etrailer made sure that I got refunded the cost of the bolts. I am very satisfied with the service I received and will defiantly be doing business with etrailer again! 170384

Ask the Experts about this Titan Trailer Coupler


  • Is the Titan Disc Brake Kit # T4843400 Good For a Salt Water Boat Trailer
  • In the Titan disc brake kit, # T4843400, the hubs and calipers are silver cad plated, the actuator is zinc-coated, and the lines are all steel. This is not an ideal set up for a salt water application. The best option would be to go with stainless steel parts. You could start with Kodiak disc brakes, # K2R35S. For 2 axles you would need 2 sets. They fit 14 inch and larger wheels and will fit a hub with a 5 on 4-1/2 bolt pattern. The rotors are the over the hub style. The actuator...

  • Can a Fold-Away Trailer Tongue Hinge Kit Work with Hydraulic Surge Brakes
  • You can use a fold-away hinge kit with a surge coupler but you will need to replace the hard brake line with a flexible hose like # T0777300 that you have referenced. For fold-away drum brake applications use # T4839000. For a 3 x 4 inch tongue use 2 adapters # T4842100. For disc brakes use # T4839100 and 1 of the adapters. You would still need flexible brake line with either of these couplers.

  • Disc Trailer Brakes for Tandem 7,000 Pound Axles
  • We do not have a kit for 7,000 pound axles but we have disc brakes for 7,000 pound axles. I have included a link to them for you. You would then need an actuator and brake lines. The actuator used in the kit you referenced is an Aero 7500, # T4839100. It fits on 3 x 5 inch channel tongues. You can use a spacer, # T4842100, if you have a 3 x 4 inch tongue. For lines and fittings, use # 9505 or # T4830000. I have included a link to some instructions for you as well.

  • Recommendation for a Trailer Brake Actuator and Coupler with a Manual Lockout for a Boat Trailer
  • This model Titan Zinc-Plated Brake Actuator, # T4747200, does not have any type of lockout on it. We do have 3 couplers that do feature a manual lockout and work with disc brakes. From Titan we have the Aero 7500, # T4606500. This is a bolt on model that fits on a 3 inch wide channel tongue. We also have a swing-away model that will fold to the side for easier storage in an enclosed space. It is # T4839100. This is also a bolt on model. For a weld on model use # T4839400. Out of these...

  • Can an Electric Lockout be Added to Titan Trailer Disc Brake Kit, # T4843300
  • There is enough space underneath the Fold Away Coupler in the Titan Disc Brake Kit, # T4843300, to add an electric lockout, # T4748800. With the lockout installed, you will not have to use the manual lockout that comes on the coupler. If you click on the last picture for Actuator, # T4839100, you will see the space underneath.

  • Availability of a 2 to 3 Foot Fold-Away Trailer Coupler Hinge with Attached Coupler
  • If you are needed a coupler and tongue that is already attached to a fold away hinge, we have # T4839000 for hydraulic drum brakes or # T4839100 for hydraulic disc brakes. These couplers will fit a 3x3 tongue using 2 of the spacer # T4842100. The pivot length is 21-1/2 inches long. But if you are looking for a 2 to 3 foot extension to the tongue you have, you will need to have a qualified welder in a machine shop of shop that works on trailers fabricate an extension for you.

  • Will Titan Aero 7500 Trailer Coupler Work with Tandem Axle Trailer with Disc Brakes on Both Axles
  • Yes, you can use the Titan Aero 7500 # T4839100 with 4 disc brake assemblies on your trailer. As long as the gross trailer weight is 7,500 pounds or less this coupler will work well for you. It couples to a 2 inch ball. I have linked a video review for you.

  • Will Titan Aero 7500 Swing-Away Actuator # T4839100 Fit a Mastercraft Boat Trailer
  • I went out to the warehouse to measure the spacing and bolt/pin diameter on the Titan Aero 7500 Swing-Away Actuator # T4839100. The distance between the pin and the pivot bolt is 3-1/4 inches on center. The pin/bolt diameter is 3/4 inches. I could not say if this is a direct replacement for the one on your Mastercraft trailer so you would need to go by the measurements. This coupler can be used for a 3 x 5 inch tongue as is. If you have a 3 x 4 inch tongue you would need a spacer...

  • Breakaway Cable Assembly Replacement Parts For the Titan Aero 7500 Brake Actuator
  • I spoke with my contact at Titan and the Replacement Push Rod and Breakaway Cable Assembly, # T4502700, is the kit you will want for the breakaway cable. You will also need the Breakaway Lever, # T4597100, and the Roll Pin, # T4599500. These are all of the parts involved in the breakaway assembly for your Titan Aero 7500 Brake Actuator, # T4839100.

  • Can Electronic Solenoid Be Used On Titan Aero 7500 Swing Away Actuator
  • Per Titan, you can use an electronic solenoid like part # T4748800 with the Titan Aero 7500 Swing-Away Actuator, part # T4839100. The electronic solenoid will be activated when the vehicle is put in reverse and will prevent brake fluid from flowing to the trailer brakes. The # T4839100 has a weight capacity of 7,500 lbs which is the weight of the fully loaded trailer with its cargo. This actuator has also got a 700 lb tongue weight capacity. Tongue weight is the tongue weight of the...

  • Preventing Titan Leverlock # T4839100 Hydraulic Coupler From Applying Brakes When Trailer is Backed
  • The Titan # T4715400 Leverlock Brake Actuator doesn't have a reverse lock-out, so your trailer brakes will apply when you try to back up. You can prevent this by installing a solenoid valve, part # T4748800 to the rear of the actuator between the master cylinder and the brake line. The solenoid has two wires, one will ground to the trailer frame, the other will connect to the reverse light circuit on the 7-way (wire from the center pin). You'll need to make sure that the center pin on...
