Features to know about

Heavy-Duty Control: 20,000 lbs Towing Capacity

This actuator is built for serious hauling. With a 20,000-lb gross towing weight and a 2,000-lb maximum tongue weight, it gives you solid braking power for heavy or multi-axle trailers. The hydraulic surge system activates automatically when your tow vehicle slows down, applying steady pressure through the master cylinder for smooth, consistent braking.

Built for Tall Trailers: 5-Position Adjustable Drop Channel

The offset drop channel and 5 mounting positions make it easy to dial in the right height when you’re setting up your coupler. The design lets the lunette ring sit lower than a standard center channel so tall trailers line up level with your hitch. It’s a clean way to match different setups without extra hardware or spacers.

Smooth Motion: Roller Design for Straight-Line Travel

Instead of sliding friction surfaces, this actuator uses a roller setup that moves straight and true as it telescopes. That design cuts resistance and helps prevent binding when the trailer pushes forward under braking. You get a smoother feel and more reliable performance every time the brakes engage.

Corrosion Protection that Lasts: Zinc-Plated Steel Construction

The zinc-plated finish stands up to weather and tough conditions, keeping rust at bay even after long use. The sturdy steel tube resists bending if your trailer ever jackknifes, and the protective coating keeps the mechanism working freely season after season.

Ready to Mount: Bolt-On with Built-In Breakaway

Bolt it onto a straight 3" wide trailer tongue and it’s good to go. The built-in breakaway system adds an extra layer of safety by activating your brakes if the trailer separates from the hitch. Everything fits tight and solid so you can focus on towing instead of constant adjustments.

Will say… I unit I purchased was much larger than what was required, will also say outside of the additional costs associated with the increased capacity, the unit simply is amazing.

Towing has never been easier. I don’t know why it took me so long to figure this out. I would highly recommend the unit to anyone who is interested!!!

It was slightly damaged upon arrival. We were able to bend the mounting bracket back and use it.

Might consider better packaging on such a heavy item. Price was good, arrival was fast. Everything was good from your end. UPS was a little rough on it.

  • Recommended Bolt On Lunette Ring
    Hey Todd. I didn't see any lunette rings in your order history. It sounds like you're describing the Buyers Products 3" I.D. Bolt-On Forged Steel Alloy Lunette Ring item # 337BDB1238. Is this what you're looking for? I saw you were looking at a brake actuator. We have a couple of those too with lunette rings item # T4852700, item # T4869820, and item # T4869800. I have linked all of our options for lunette ring couplers below. If you have a picture of yours you can email it to the address...
