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 you shift the tow vehicle into reverse. To use this feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.

Really nice, I was able to use all of the parts to re-build my actuator without having to cut or weld my trailer. Works great

Have not installed at time of writing, but is a perfect match to my old unit! Looking forward to install! Thanks trailer.

The Dexter hitch is performing well, although I have found it needs to be lined up precisely to the ball to connect...low tolerances that way. Another concern I have, although it has no direct bearing on this hitch, is that I recently learned some jurisdictions are only allowing tandem trailers with electric/hydraulic brakes...I guess they feel solely hydraulic surge brakes are "less" safe? You guys might consider a small note about this in your descriptions.

@Bruce I am not 100 percent sure on their thinking however electric over hydraulic brakes gives the quicker, smoother control of electric brakes combined with the stopping power of hydraulic brakes. We always recommend checking with DMV to see what is required when it comes to trailers and brakes.

I want you to know I am very happy with the actuator. I installed it and have used the boat several times since. The actuator is quality and the service from e-trailer is always excellent. I will continue to use your services as needed.

  • Can You Reverse With Brake Actuator T47457207K And The Brakes Not Lockup
    The Dexter Actuator part # T47457207K has a lockout you can then reverse the trailer without the brakes engaging. In summary, no lockout means you cannot reverse the trailer without the brakes engaging and lockout means you can reverse the trailer without the brakes engaging. Please note, in order to use the reverse lockout feature you will need to have either a 5-way trailer connector, 4 to 5-way trailer connector adapter, or 7-way trailer connector. The Curt Trailer Connector Adapter...

  • Surge Brake Actuator Recommendation for a Boat and Trailer that Weigh 2,200 lbs
    A 7,000 lb capacity actuator like the part # T47457207K would work great with your boat and trailer that weighs a total of 2,200 lbs. This is a multi-fit coupler that will work with virtually any hitch ball size.

  • Replacement Dexter Axle Disc Brake Actuator for Tandem 3.5K Axle Trailer

  • How Does Reverse Lock Out Solenoid of Titan Surge Actuator Get Wired
    The Titan Actuator part # T47457207K should have came with instructions but sometimes like anything they get misplaced before shipping. With the reverse lock out solenoid basically one of the wires runs to the reverse light circuit of the vehicle and the other gets grounded. The wires aren't polarity sensitive so either could be used as the power and ground wire. There isn't a coupler lock available for this coupler due to it being the multi-ball setup that fits more than one ball size....

  • Recommended Surge Brake Coupler For Disc Brakes With Electric Lockout
    The best replacement for your coupler for disc brakes is the Dexter Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - Adjustable Ball - 7,000 lbs # T47457207K. This has the electric lockout built in for free backing so you need to only shift into reverse for this lockout to engage and allow you to backup without trailer brakes. It has a master cylinder designed for disc brakes that require a much higher pressure than drum brakes. The Atwood Actuator you asked about is not for disc...

  • Required Mounting Hardware For Titan Zinc-Plated Brake Actuator w/ Electric Lockout # T47457207K
    The Titan Zinc-Plated Brake Actuator w/ Electric Lockout # T47457207K requires 2 grade 5 bolts that are 1/2" x 4" to bolt to the trailer tongue.

  • Replacement Brakes for Sailboat Trailer With 3500 lb Single Axle
    A 3500 lb axle would typically use a L68149 inner and L44649 outer wheel bearing and the hub would have a 5 on 4-1/2 inch bolt pattern so you'll want to confirm that by pulling a hub and getting the reference numbers off the cages of your existing bearings. If this is what you have, then you do indeed have a 3500 lb axle and the parts I recommend below will be based on that assumption. If the above is true, you'll have 10 inch brake assemblies, and I'd recommend # 40716-15 galvanized brake...

  • Replacement Actuator Recommendation For An Older Atwood 85736 Actuator
    Since the Atwood 85736 has been discontinued for quite some time, we as a result, do not carry it's replacement parts, however I do have another alternative. I know it's not ideal, but since it's going to become harder and harder to find replacement parts, I recommend just upgrading your entire unit instead. A great option is the Titan Zinc-Plated Brake Actuator w/ Electric Lockout # T47457207K. This unit will let you back up without activating electric trailer brakes thanks to the electric...

  • Replacement Surge Brake Actuator For Atwood 85736 That Is Discontinued
    Your best route is to replace your entire surge brake assembly as Atwood no longer produces any parts for their brake actuators. The Titan Zinc-Plated Brake Actuator # T47457207K is going to be your best replacement available. It is specific to disc brakes and has a 7,000lb weight rating while your Atwood 85736 has a 6,000lb. This does have a bolt on design where your Atwood is likely welded on so you will need to cut off your actuator and drill holes to bolt on the new actuator. The...

  • Disc Brake Actuator with Electric Lockout for Magic Tilt Trailer
    For your Magic-Tilt tandem axle boat trailer with disc brakes and a straight tongue I recommend Titan Disc Brake Actuator Coupler # T47457207K. This 7K bolt-on coupler has an electric lockout and I like it because it features a multi-ball fit so it will work with 1-7/8-inch, 2-inch and 2-5/16-inch hitch balls.

  • Replacement Surge Brake Actuator For Venture Commander 6000 Boat Trailer To Fit Multiple Ball Sizes
    You will need the Dexter Zinc-Plated Brake Actuator # T47457207K for your Venture Com-6000 Commander boat trailer. This actuator has the multi-fit coupler for 1-7/8", 2" or 50 mm ball sizes. It includes an electric reverse lock out actuator to prevent the brakes from activating when driving in reverse. You can verify this will mount on your trailer as the 1/2" mounting bolts for this coupler are spread 3" on center. You will either need to reuse your current bolts or source new bolts locally...

  • Does 5-Way need to be Installed on 16 Ram Pickup to Activate Electric Lockout on Actuator
    You do need at least a 5-Way connector like what you find with adapter # 20036 (designed for this type of use) so that the reverse lockout function is activated on your Brake Actuator w/ Electric Lockout # T47457207K. If you only had a 4-Way on your Chevy Avalanche then I am a little confused as to why you were able to back up your trailer but regardless, you need to connect the actuator to the reverse light function on your 2016 Ram pickup so that you can back your trailer up.

  • Where is Voltage Coming From When Using Actuator With Electric Lockout for Hydraulic Disc Brakes
    When using the Dexter Zinc-Plated Brake Actuator w/ Electric Lockout - Disc # T47457207K, the voltage for the solenoid is coming from the reverse light circuit. It will supply voltage only when the reverse light is on when using a 5-way connector. If you need a 5-way you can use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036, and I have added a link to a video install for you to check out as well. I have added a link to a help article on trailer wiring you may find useful,...

  • Replacement Brake Actuating Coupler for Ranger Boat Trailer
    Unfortunately, we don't carry a Dexter 48970, nor could I find anything about that part. Assuming your boat and trailer have a combined weight of less than 7000 lbs and has disc brakes and a 3 inch wide tongue, the Titan # T47457207K surge brake actuator you'd looked at would work well for you. The coupler is compatible with 1-7/8, 2 inch or 50mm trailer balls.

  • Parts Needed to Convert from Drum to Disc Brakes on My Saltwater Trailer
    Your outer bearing # LM67048 will have the same 1.250" inner diameter of the # 15123. So the Kodiak Disc Brake Kit # K2HR526DKG will fit the spindle on your axle without issue. I will say that you should check the bolt pattern on the back of your current brakes to make sure you have a 5 bolt, however. I included a picture of how it should measure as well. As to the actuator, this will depend on if you were looking to go with a surge style actuator or electric over hydraulic. If you are...
