Recommendation for Adding Electric Trailer Brakes to Trailer with 3,500 lb Axles & 5 on 5 Inch Hubs


just wanted your recommendation on which brakes and drums would work best together? I have a 16 ft. trailer 3500 lb axles with 5 on 5 in wheels. I will need wiring also and what gauge will I need?

For your 3500 lb axles, I recommend starting with the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies # AKEBRK-35-SA. These assemblies will self-adjust to ensure you have the best braking without needing to manually adjust them every few months.

Then for your 5 on 5 inch hubs, I recommend the Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 5 on 5 # AKHD-550-35-K. If you have the spindles with the integrated grease zerk, then you will want # AKHD-550-35-EZ-K instead. Most 3,500 lb axles use the same bearings and seal, but you may want to double check to be sure yours match.

Then for your trailer wiring, I recommend the 10 gauge # 10-1-1 wire sold by the foot for your brake magnets. This is run from one side of the magnet to the junction box and then to the 7-way. The other wire on the magnet is grounded to your trailer frame. For the junction box and 7-way, I recommend the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 using ring terminals # 44-5310A. I've attached a video and article to assist.
