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.

Electric reverse lockout with solenoid is automatically activated when the tow vehicle is shifted into reverse. To use this feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.

EASE OF INSTALLATION: Definitely not plug and play. RELIABILITY: Excellent. DURABILITY: Product used exclusively in salt water environment. Still looks new. No Rust! RECOMMEND TO OTHERS: Yes, but know you are in for a major task.

I replaced a twenty four year old coupler with the Titan T4750820.
My previous system had a separate coupler, hydraulic pack, and battery box. I could not keep up with the effects of salt water and time. It became a maintenance and safety nightmare.
The installation of a titan hydraulic coupler and a Tekonsha P3 brake controller has restored my confidence in my braking system.
The staff at etrailer.com was first class in answer all my questions and making sure I got the right gear the first time.



by:

Love the coupler, heavy, built well, nice unit. I only wish e-trailer would of notified me that it was on back order prior to taking my money. Ended up moving a vacation back about a month because of it.



by:

The latch is a pain, it's always getting stuck. It is such a pain that I just ordered the Demco. Save yourself the headache and buy the better product from the get go.

  • Replacement for GDC120 Actuator for Heritage Triple Axle
    The Titan Actuator part # T4750820 would be a great solution for replacing the GDC 120 you have on your triple axle boat trailer. It has more than enough capacity and is a very reliable actuator.

  • How Does an Electric Reverse Lockout Solenoid on a Titan Coupler Get Wired
    On the reverse lockout solenoid on Titan coupler # T4750820, one wire will need to be grounded to the trailer frame. The other wire needs to connect to the reverse light circuit on the trailer side connector. When the vehicle is placed in reverse it powers the solenoid and will not let fluid back to the brakes allowing you to back the trailer without the brakes engaging.

  • Advantages of Manual vs. Electric Reverse Lockout on Actuator Coupler
    A trailer actuator-coupler with an electric reverse lockout feature, such as Titan # T4750820, allows you to reverse your trailer without having to get out of the vehicle to first engage a manual lockout lever. The internal solenoid in the actuator takes care of this automatically when you shift the vehicle into reverse; that reverse light signal is the trigger that tells the actuator to block the flow of fluid through the brake lines. Blocking the flow of brake fluid allows reversing the...

  • Recommended Replacement Surge Brake Actuator and Disc Brakes for Boat Trailer
    Is the trailer's GVWR 5,200 pounds or is that the axle capacity? If it's the axle capacity and a tandem axle trailer I recommend the Titan brake actuator, part # T4750820, that's rated for up to 12,500 pounds. If the trailer's maximum weight capacity is 5,200 pounds then instead I suggest part # T4745720. Both are zinc-plated to preven corrosion and include an electric lockout. If your axle isn't rated for 5,200 pounds let me know so I recommend the correct disc brakes. If they are...

  • Parts Needed to Convert Titan Model 6 Drum Brake Actuator # T4079200 to 4-Disc Brake Operation
    It is possible to rebuild a drum brake actuator to handle the higher pressure and fluid displacement required for disc brake assemblies. However, in the case of your four Kodiak disc brakes (part # K1HR35D) for use on a tandem axle trailer these will require more fluid displacement than can be provided even by a modified Model 6 actuator. A drum-to-disc-modified Model 6 actuator could handle the requirements of two brake assemblies but not four, according to my contact at Titan. He advised...

  • Will the Titan T4750820 Actuator Replace Global Direct Components GDC-120 Without Drilling New Holes
    Since the Titan Zinc-Plated Brake Actuator # T4750820 that you referenced has a weight capacity of 12,500 lbs and a tongue weight capacity of 1,250 lbs it will serve well as a replacement actuator for your application. The mounting holes are spaced differently than what you show which means you will need to drill new holes into your trailer tongue. Your mounting holes are spaced in a straight line where the mounting holes for the Titan actuator form more of an arc. Instead of the Actuator...

  • How to Install the Backup Solenoid on Titan Disc Brake Actuators
    The Fitting in the back of your actuator, # T4750820, will need to be removed to install the Solenoid Valve for Titan Brake Actuators, # T4748800. I have posted a photo showing this fitting. Once the fitting is removed you will install the solenoid valve directly into the back of the master cylinder, see second photo, then attach the brake line from the trailer directly to the solenoid. The fitting that was removed will not be needed.

  • Is Titan 10,000 Pound Brake Actuator Compatible with Kodiak Stainless Steel Disc Brakes
    For your brake actuator to be compatible with your Kodiak stainless steel brakes, the actuator will need to be a disc brake actuator. Kodiak only makes disc brakes. If your actuator is a drum brake actuator, not a disc brake actuator, it will not be compatible with the Kodiak disc brakes. If your Titan actuator is made for disc brakes, it will work well with your Kodiak brakes. The Replacement Master Cylinder Assembly # T4749501042 is only compatible with Titan Model 10 and Model 20 disc...

  • Complete Disk Surge Brake Setup Recommendation for a Rogue Tandem Axle Boat Trailer
    We have everything you need, just not in one kit. For a disk brake kit that will bolt up to your 4 bolt brake flanges and will slip over your 5 on 4-1/2 inch bolt pattern you would want the part # K2R35D for a dacromet finish. Or if your trailer will see salt water I would recommend the stainless steel kit part # K2R35S. You will need a quantity of two of these kits for both axles. For a brake line kit you will need the part # DM5425. And then for a surge brake actuator you would want...

    The direct replacement for your Titan Model 6 4079200 is the # T4079200. However, you have disc brakes on your trailer, not drum brakes. For a replacement designed for drum brakes you can use the # T4750820 which is the Model 10 and replaced the Titan 4750820. This has a 12,500 lb capacity and also fits a 3" channel.

  • Troubleshooting Electric Reverse Lockout on Titan Model 10 Coupler
    The Titan Model 10 Actuator # T4750820 uses an electric reverse lockout that relies on the signal from the vehicle's reverse light circuit. That signal engages the lockout solenoid that prevents the actuator from compressing (and engaging the brakes) when you back up. If your vehicle's trailer connector has damage to its reverse light signal wire this would cause the brakes to remain engaged. You can refer to the linked photo of a 7-way vehicle socket to note that the center pin is usually...

    I have attached a link to a helpful article that explains everything that is needed when adding hydraulic disc brakes to your trailer. In addition to a kit like part # K2R1258L12 you will need to make sure you have the right brake mount flange, and you will need to add hydraulic brake lines to your trailer. You will also need a surge brake actuator like part # T4750820 installed on your trailer frame. I have attached links to the brake lines we offer, and to the actuators we offer.

  • Tips For Removing Stuck Master Cylinder Cap On A Dexter T4750820 Actuator
    Sometimes dust and dirt can get down in the threads of the master cylinder cap and they can get stuck on there real good. Unfortunately there is not really a trick to getting it off, other than using force. A little WD40 may help but I would use that as sparingly as possible. If you have no choice but to break the cap, it can be replaced with part # T4830601.
