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.

Video Transcript for Titan Brake Actuator - Surge Brake Actuator - T4747210 Review

Today, were going to take a quick look at the Titan zinc plate brake actuator with lockout shield, part number T4747210. This actuator is designed to work with trailers that are equipped with disc hydraulic brakes. The nose of the coupler is fitted for a 2-5/16 inch trailer ball. A hydraulic actuator works on momentum. As you brake in the vehicle, the trailer will push against the vehicle on the ball and the system will compress activating the master cylinder and then sending brake fluid out to the line and back to your disc brakes.The coupler is made out of steel and finished in a zinc plating to help protect against corrosion. Up top, youll see we have a breakaway system here.

Theres a steel cable and youll fit the hook end onto your tow vehicle. That way, if the trailer were to ever come separated this cable will pull tight, activate this lever, and apply brakes to the trailer. Up top here, youll see our fill cap for the brake fluid reservoir.Its a bolt-on system. On the housing here, youll see a series of boltholes that you can use to bolt this directly to your trailers tongue.The latch system works like this: Well pull up on this ring so that we can release the handle and then pull up on the handle. To close it, well just push forward.

You do want to make sure that this ring is seated properly inside the notch as this is going to help prevent the handle from coming open when trailering down the road. Theres a hole up here that you can use with a coupler lock to make sure that it doesnt come open when youre trailering and also protect your trailer against theft while you have it in storage.Underneath, well show you how the wedge system works with the ball. Inside, youll see a tubular piece of metal back here. This is going to come against the back of the ball and secure it and prevent it from coming out. Well pull up our trigger release and open the latch, and that piece moves up and away allowing us enough room for us to get our 2-5/16 ball into the socket.

Well close it and that tube comes back down and bites on the back of the ball holding it into place. Underneath, youll see our braking system. The inner coupler tube slides against the outer housing here and pushes against the master cylinder sending brake pressure out back here where our brass fitting is.The inside width measures in at 3 inches as this actuator is designed to fit with 3-inch wide channel tongues. It has a maximum trailer capacity of 8,000 pounds and a maximum tongue weight capacity of 800 pounds. Titan does cover this with a one-year warranty.There is a built-in cover here protecting the internals and theres also a place where you can mount a solenoid valve, thats sold separately, to allow the actuator to lock out when you have the vehicle in reverse so that it doesnt apply brakes while youre backing up the trailer.

Thats it for our quick look at the Titan zinc plated brake actuator with lockout shield, part number T4747210. .

Average Customer Rating:  4.6 out of 5 stars   (5 Customer Reviews)

Bolt-on, surge-type actuator is zinc plated for increased corrosion resistance and comes with integrated, heavy-duty coupler. Unique roller design helps reduce resistance.


This actuator is the exact replacement for the model 6. It also came with a solenoid, which was a good surprise.
I had brakes sticking, but not anymore.




Works great.

  • Will Titan Actuator T4747210 Replace Titan Model 6 Actuator?
    You can use the Titan Zinc-Plated Brake Actuator # T4747210 as a replacement for your current Titan Model 6 actuator. The actuator you referenced is for disc brakes and fits a 3" wide channel tongue. It has a lockout shield so would be compatible with your lockout. I've added a link to a video review of this part for you to take a look at.

  • Replacement Actuator for Dexter 48867 80LP
    That is a Tie Down repair kit part number I was able to find elsewhere online but we do not have ability to get. Easiest solution we have would be a new 8,000 lb rated surge actuator from Titan with the part # T4747210 and you'd be set.

  • Recommended Surge Brake Actuator For 7800lb Tandem Axle Boat Trailer W/ Disc Brakes
    You would have no problems what so ever going with an 8000lb rated coupler since you are only at 7800lbs, and going with a 12500lb coupler would cause a little more jerky braking due to the different size springs used for the trailer to apply the brakes. With that said I recommend the Titan Zinc-Plated Brake Actuator w/ Lockout Shield - Disc - 2-5/16" Ball - 8,000 lbs # T4747210 which is rated for 8000lbs and is designed for disc brakes like what is on your trailer.

  • Replacement Titan Model 6 Actuator and Brake Line Kit Recommendation for Trailer
    If as many parts of the coupler need replacing that you mentioned I would recommend just replacing the whole thing. It will save you the hassle of rebuilding the coupler and will give you all new components. The part # T4747210 would be a great choice as it is basically exactly what you have. For a single axle brake line kit the part # 18SI-BLKIT would work well.
