Solution for a Custom Built Trailer to Provide Hubs and Brakes for Wheels

Question:

I some help confirming how I am thinking about axle measurements and what you have available. Trailer box / frame is 72” wide, overall trailer width is to be 90” using 205 width tires 8”. For a 72” wide frame I am assuming I need spring centres at about 69” correct inset on 72” frame? and hub face at 82” working backwards from 90” total width minus 1x tire width at 8” with @ zero offset. That should leave a mole clearance for the and tires I think? - 3500 lbs ea - 4” - ez lube - one idler/one w/brakes

From the information you have provided, it sounds like your calculations are all correct. The main issues would come from the fact that in order to have the dimensions you are wanting there is no off the shelf axle available to accomplish that. I do have an alternate solution for you though.

You can use the Timbren Axle-Less Trailer Suspension System # ASR3500S06. This is an axle-less solution that will provide you with the 3,500 lb., 4" lift EZ lube style you are wanting. Since you are wanting a dual set-up you would need to purchase 2. Going this route would end up putting you around 2" wider (1" on each side) than the 90" you were wanting using 8" wide 205 tires. With this system, you also would not need leaf springs.

This is the only way to accomplish this without having custom axles made.

You can then use the Dexter Trailer Hub and Drum Assembly # 84656UC3-EZ (x2) with the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-468-469 and the Dexter Trailer Idler Hub Assembly # 84545UC1-EZ (x2).
