Replacement Surge Brake Coupler for Boat Trailer

Updated 06/01/2020 | Published 05/28/2020

Question:

Im looking to replace the coupler / master cylinder assembly on my boat trailer. I cant seem to find the right model on your website, nor can I find any part #s on my trailer. I do have some pictures. Can I send you some pictures of my coupler to see if you have a replacement? Standard 2 ball, the coupler and master cylinder slide into the tongue of the trailer and it has 2 pins that keep it secured. Appreciate your help, thank you.

The coupler you are seeking is a surge brake coupler. You may not have the same look as your previous coupler as styles can change, but you need to make sure you have the correct capacity rating for your trailer and the correct coupler as drum brakes and disc brakes have different psi ratings. You will also need to determine if you need a manual lockout, electric (reverse light circuit) lockout, or no lockout.

Because you already have stated it is a 2 inch ball, I've linked the pages to your options. One link is for drum brakes and the other link is for disc. I have also attached a help article to assist.
