I would be happy to help.

The closest 2000lb trailer axle we offer for your 50" wide trailer is the 60" Dexter Trailer Axle Beam with Standard Spindles # T20BTR-6048, but this would only give you roughly 3/4" of frame clearance when used the narrowest 15" wheels we offer which is the Kenda Karrier ST205/75R15 Radial Trailer Tire with 15" Black Mod Wheel - 5 on 4-1/2 - LR C # AM32238B. It is recommended to have at least 1-1/2" clearance between the trailer frame and the tire so I have another option.

Instead I recommend the Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS01 which has the 2000lb axle rating you are looking for, but will work with any width trailer. Since the # ASR2KHDS01 has a built in AEON progressive-rate main spring you will not need leaf springs or any other suspension hardware.

To complete the Electric Trailer Brake installation I recommend the following parts:

Trailer Hub and Drum Assembly # AKHD-545-35-EZ-K
Trailer Idler Hub Assembly # AKIHUB-545-35-G-EZ-K
Electric Trailer Brake Kit # AKEBRK-35-SA

Since you are only wanting one set of trailer brakes, I recommend putting them on the front assembly as typically tandem axle trailers have 60% of their load on the front axle, and 40% on the rear axle.

While you didn't mention needing wiring to activate your new electric trailer brakes I recommend the Trailer Wiring 7-Way Upgrade Kit w/ Junction Box # HS381-9000 which will give you the 7-way connector needed to plug into your vehicle, but will also give you a nice junction box to make all of your wiring connections. You will also need 10 Gauge Wire # 10-1-1 to go from the junction box to the electric trailer brake assemblies, and using Heat Shrink Butt Connectors # DW05745-5 will provide a weather tight connection.

Lastly for 15" wheels with radial tires I recommend the # AM32238B which has a black wheel, or # AM32395 which has a white wheel. Both of these wheels use the 5 on 4-1/2 bolt pattern which is what the idler hub and hub and drum assemblies mentioned have.

You will be able to find the most up-to-date prices for all of the products mentioned on the product pages right above the add to cart button.

I included videos for each of the products mentioned, and a link to a helpful article on adding electric trailer brakes for you to take a look at.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
