Question:
Hi I have a Demco AT6000 car hauler trailer. The Surge Brake Actuator needs to be replaced. The old unit currently fitted is a Demco DA91 so I was looking for same to replace with. Looking on your site I dont see a DA91 ? Do you sell the DA91 or is that one superseded? the DA86 looks similar? if so - which unit do I need ? Thanks BRH

Hey Brian!
There are actually a lot of options you can use. The DA91 has a lot of variants from its connection at the frame, the finish, the style of coupler, to how it attaches to your trailer (a frame and channel mount).
For example coupler part # DM8609101, part # DM8760011, and part # DM8509602 are all a DA91 at it's core.
If you can reply to the email you get with pictures I can have a better idea of what one will be the best fit for you. Also if you can tell me if the trailer had drum or disc brakes.
