Hi Jacob!

The Demco Surge Brake Actuator - Drum - Primed - 2" Slide-Lok Coupler # DM8509202 is pretty unique with that style coupler and is only available for drum brakes. I do have another option that is pretty similar that you might be interested in though:

Demco Hydraulic Brake Actuator w/ Drop - Disc - Zinc - 2" Ball - 8,000 lbs # DM8669113

This has a different coupler, which I think is much easier to use, but you could swap that out for something like the Bulldog Collar-Lok Coupler w/ Pin - 2" Ball - 3" Channel Tongue - 7,000 lbs # BD028243. This would need to be drilled to have it mate to the actuator, but it could be done fairly easily.

Out of curiosity, would you be interested in a completely different coupler? We do have a bunch of other options.

Hey Jacob, how did things go with the Demco disc brake actuator and the Bulldog coupler setup for your car hauler? Your update could make it easier for others working on similar brake conversions.
