The EZ-Latch coupler makes hitching simple and secure. You don’t have to fight with a trigger latch or guess whether it’s locked on. Just lower the trailer onto your 2" hitch ball—the latch snaps into place automatically with a solid click. There’s no need to hold the latch open, and you can drop in a locking pin through the side hole if you want extra theft protection. This setup gives you quick, repeatable hookups and a lot more confidence before you hit the road.
If your setup needs a little help lining up, the built-in 4" drop takes care of mismatched heights between trailer and tow vehicle. It keeps the trailer level for smoother towing and steadier braking. The actuator bolts right onto a 3" wide tongue using 1/2" x 4-1/2" Grade-5 bolts (not included) and follows a standard three-hole pattern with centers at 3" and 12-1/2". That means easier alignment and no custom drilling when you’re replacing an old unit.
When you ease on the brakes, the Demco DA91 actuator pushes fluid from its glass-reinforced nylon master cylinder straight to your drum brakes. The automotive-style diaphragm cap keeps contaminants out, while the large reservoir holds more brake fluid to help prevent running low during long hauls. The inner member glides on a heavy-duty, self-lubricating plastic liner for consistent movement every time you stop.
This actuator is made from heavy-duty steel and coated with zinc that lasts twice as long as standard plating, proven by its 200-hour salt spray rating. That’s real peace of mind for trailers that see water, mud, or road salt. The included breakaway cable with snap hook adds another layer of safety—if the trailer ever separates, it pulls tight to activate the brakes automatically.
With an 8,000 lb gross towing weight and 800 lb maximum tongue weight rating, this surge actuator is ready for serious work. It doesn’t need an electric brake controller to function—just hitch up, fill the reservoir, and go. As you slow down, momentum compresses the actuator and applies hydraulic pressure to your drum brakes for smooth, proportional stopping every time.

Fine - I don’t use the brakes - just the tongue as that is the same model that was on there before
