I am in the process of swapping out the brakes I have with another brand as well as adding brakes to my 2nd axle.
I decided to go with Kodiak. Big reason: they are here in Texas (Fort Worth) and I can order parts in the future with lower shipping and/or pick up in person.
Jesse at Kodiak is super helpful! If you have questions in matching up part #'s or looking for advice, this guy is someone you need to talk with.

If you need brake products I suggest you give these 2 sources a look.
If you're looking to save even more money, I have a set of brakes with rotors that I will probably be posting for sale once I get the chance to clean them up. They are UFP brand. 10 inch rotors, 5 on 4.5, 3500 axle set up.
With my research, the 10 in / 3500lb axle set up is pretty universal across the board.
These brake calipers have 2 bolts that mount using the top 2 holes of the flange at the end of the axle that is right behind the spindle. They are aluminium calipers - no rust.
