Backing up a loaded trailer can be a pain if your brakes keep engaging. The electric reverse lockout on this actuator ties into your reverse light circuit, so when your backup lights come on, the brakes stay off. No manual pins or levers to mess with—just shift into reverse and go. It’s a small feature that makes launching a boat or backing up an incline way easier and stress-free.

This actuator uses surge pressure to activate your trailer’s hydraulic disc brakes automatically—no brake controller needed. Inside, a rustproof aluminum master cylinder pushes fluid smoothly to the brake lines every time you slow down. With a 7,500 lbs gross towing weight rating and easy weld-on mounting for a 3" wide tongue, it’s built for dependable braking on heavy or multi-axle trailers.
The low-profile body keeps the coupler latch flush with the actuator housing, giving your trailer a clean, streamlined look. Since it’s primed and ready to weld, you can paint it to match your trailer once it’s installed. The latch won’t stick out or snag, so you don’t have to worry about bending or breaking it when hitching up.
Hooking up is fast and secure thanks to the push-button latch system. Just drop the coupler over your 2" ball, close the latch until it clicks, and insert the tethered safety pin. The latch only engages once the ball is fully seated, keeping your connection solid even over rough ground.
Built to weld directly onto your trailer tongue, this actuator has been certified by the SAE for safe and consistent operation. It includes a breakaway cable with an S-hook for extra protection if the trailer comes loose. The welded setup keeps everything rigid and aligned for reliable braking performance every time you tow.

Nice product
I have not got it on the trailer yet can't wait to use it it looks awesome hope it works as good as it looks
Fits well and works as it should
It was exactly what I needed for my MASTERCRAFT boat trailer. I pulled the old one out and slid the new one in. Very easy to do
Just what I wanted. I am building a custom trailer for my vintage boat. I have used these actuators in past projects. etrailer has great pricing and fast delivery every time.
Original item went on back or
Bought this for my 1995 Mastercraft Boat trailer. Works great, wasn't worth rebuilding the 30 year old unit. The solenoid to disable the brakes when backing up is awesome!
Great service getting the rite parts
Perfect replacement for the same item that wore our after 12 years of use. Simple install. Remove the old actuator - unhook the brake line (which I was afraid would leak, but doesn't,) unhook the blue wire from the solenoid, pull the two pins, and pull it out. Reverse the process to install the new one.
Only question was, where does the white wire on the new unit go? Old unit did not have a white wire. Answer is that it's a ground, so just find a ground and hook it up.
Of course, you must now bleed the air out of the lines, but anyone who is tackling this job themselves has probably bled brakes before.
PS. I bought this unit, which comes with the primed steel outside piece, because it was cheaper than buying the internal unit by itself.
