Hello Andy, good question. The standard axle tube diameter for a 3,500 lb axle is 2-3/8". All of the 3,500 lb axles made today will have this same diameter. The 3" diameter 3,500 lb axles are an older design that is basically no longer made, so the # TSR3500S06 kit would really only be applicable for older trailers. For the standard 2-3/8" 3,500 lb axles you can use part # TSR3500S04.
If you need an axle with a 3" tube diameter you would have to go with an axle rated between 5,200 and 7,000 lbs. Feel free to reach out if you have any other questions.
