U Bolt Torque Thread (Rusty Calling You)

hmm i hadn't thought of the tubes... i recall them being at least 1/8" - 3/16" though, i dont think 90lbs would bend it?

It's 90 lbs of twist on the nut, but how much down force is that on each U bolt?

A lot more than 90 lbs.:D

There is a sort of gear reduction at work there, that I think you are not taking into account.
