Adding Electric Brakes to Northern Tool UltraTow 5x8 Aluminum Frame Trailer

Question

Question:

I am looking to replace the axle on a Northern Tool Ultra Tow 5x8 Aluminum Trailer. I am not looking to increase capacity as much as gain electric brakes. What are your recommendations?

Because the trailer doesn't have a traditional size, in order to upgrade to trailer brakes you will need to have a welder install the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34 which will require the proper jig to ensure placement and alignment. Then you will need to measure your spindles to help get the correct replacement hubs to add the integrated drum. I've attached a photo of the locations to measure with a digital caliper like # PTW80157 to assist in getting compatible drums by measuring the inner bearing, outer bearing, and seal locations.

The best alternative is to use the Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,000 lbs # ASR2000S02. This will replace your leaf spring suspension and your axle. You will need to use 2x2 inch square tubing between the assemblies (not included). Then you can use the Trailer Hub and Drum Assembly - 3,500-lb E-Z Lube Axles - 10" Diameter - 5 on 4-1/2 # AKHD-545-35-EZ-K and the brake assemblies # AKEBRK-35-SA. These will work with your current wheels. We don't have any straight axles under 3,500 lb capacity that include the brake flange, but you may want to consider that as well so I've linked the page to your options.

Then you will use # 10-1-1 to wire your brake assemblies and I recommend using the 7-Way Molded Trailer Plug with Junction Box # HS381-9000 along with ring terminals # 44-5310A to complete your wiring upgrade.

The most I was able to find about the Coleman 4735CC201 leaf spring is that it's rated for 1,000 lbs which means it goes to a 2,000 lb axle. For that application we have the 4-Leaf Slipper Spring w/ Radius End #e69SR which measures 25-4/8"…

I think you will be better off simply replacing the axle. I recommend a replacement like the Dexter Trailer Axle w/ Idler Hubs - EZ-Lube - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs, #35545I-EZ-89, since you have no brakes. This will give…

From what I found online, the Ultra-Tow tag-along trailer uses a 4.80-12 tire. Trailer tires will typically have a 65 mph speed rating at a minimum, so I don't know if the speed is limited by the tires used or by some other characteristic of the…
