Question:
I need to replace the surge brake actuator on my 2018 Coyote trailer. Its dual axle and has disc brakes. The current actuator is made by Knott, which I understand is no longer produced. I need help identifying the proper replacement actuator.

Thanks for reaching out Michael,
There's few things we want to know to ensure you get the correct replacement.
What is the current Hitch ball size 2" or 2-5/16"?
Does the actuator bolt or weld on to the trailer?
What is the mounting bolt pattern and/or spacing?
What's the trailer weight capacity?
Does your current actuator have a reverse lockout solenoid?
If you'd like to send a few photos of the current actuator, the mounting area and any model, serial number or stickers (if they’re still readable), we can match you with the replacement for your trailer.
What do you usually tow with the Coyote?
