Question:

Dear Andrew. Thank you very much for your promptly answer. This is an aluminum trailer, I prefer to not make modifications to the chassis like weld o add a 2” tube reinforcement to hold the Timbren Axle-Less Trailer Suspension System. If prefer to weld and accomplish by professionals the mounting flange and go to electric brakes using my axle and splinde. Please let me know all the parts I need to do that, also the dash actuator part number, switches and connectors. Thank you very much.

It is possible to weld on a brake flange such as Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34 for 1-3/4" round axles, but it takes a qualified welder and even then it can be difficult to accomplish. A better solution is to upgrade your current axles with something like Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Regular Tires - 2,200 lbs # ASR1THDS01, or if you need lift spindles you can go with Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Regular Tires - 2.2K # TASR1THDS04.

These suspension systems can be bolted or welded onto your trailer and you may need to use 2" square tubing for reinforcement. These have brake flanges already installed onto them, so you can simply add a brake assembly like Dexter Electric Trailer Brake Kit w/ Parking Brakes - 7" - Left/Right Hand Assemblies - 2.2K # K23-103-104-00 then add a hub and drum assembly such as Dexter Trailer Hub and Drum Assembly for 2,000-lb Axles - 7" - 5 on 4-1/2 # 8-257-5UC3.

Your axle should be 1-3/4" in diameter in which case you can use Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34; I recommend measuring just to verify your axle size. Then you can install a brake assembly such as Dexter Electric Trailer Brake Kit w/ Parking Brakes - 7" - Left/Right Hand Assemblies - 2.2K # K23-103-104-00. Next you will need a hub/drum assembly and for this I recommend Trailer Hub and Drum Assembly - 2K Axles - 7" Diameter - 5 on 4-1/2 - L44643 - Pre-Greased # AKHD-545-2-1K. Now you will need to convert your trailer's wiring to 7 way so that it can be compatible with a brake controller. For this, I recommend using 7-Way Molded Connector w/ 15' Cable - Trailer End # 50-67-103. I attached a 7 way pinout diagram to help with the install. If your tow vehicle already has a 7 way then you are good to hook up the trailer, but it probably has a 4 way flat in which case you will need to install Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7 which provides a 7 way connector compatible with brake controllers. Last but not least, you need a brake controller. I recommend the Tekonsha BRAKE-EVN Trailer Brake Controller - 1 to 4 Axles - Proportional # TK63VR because it is very easy to use and works well. I attached some demonstration videos for you to check out.
