I found a surge coupler that will work well on your trailer. However, the part that you referenced, # DM8204011, is designed only to work with drum brake systems. Disc brake systems need higher psi for the calipers to activate the brakes and drum surge coupler cannot supply the correct pressure.

I recommend the Demco Hydraulic Brake Actuator w/ Drop for Disc Brakes, # DM8204311. This surge coupler is almost identical to the one you referenced, except it is rated to be used with disc brakes.

Hey Kris, the Dutton Lainson winch part #DL15440 does not come with a strap so you will need to order one with it. The part #DL24250 will work great with this winch as it is correct width, is 25 feet in length, and has a capacity of 3,700 lb WLL and…
