I don't know much about Belltech lift kits, but they're offering a coilover kit with a differential drop and new spindles. It is 4"-7.5" of lift. Says it will fit 40's but 37's are recommended...
This trailer is 81" between the fenders. The D-ring on the wheel straps I have did not fit through the wheels. I had to use axle wraps. Ford has the track width as 66.9", but I'm not sure if that is center to center or outside to ouside.
I also called. She told me that Ford is on target to send out an email by the end of May. I then asked her "So, by tomorrow?". She just repeated the same exact thing about Ford being on target.
