It's odd to me that you would drag this up from the heap pile... I think I would have left it dead.
As someone in the Steel industry, before I drug this back up, I would still reach out to a metallurgist to review the tensile strength claims of your specific hollow tube versus another's solid stock. Especially before making broad claims without verified certs of both, and not in general but specifically both products involved. The chemistry of steel can be vastly different. That picture of the torn RSB speaks volumes.
The question remaining for me is concerning the recommendation to disconnect the RSB to avoid damage to it? Other than for certain coil over suspensions that say they aren't necessary, I would think having both front and rear disconnected, especially on off-camber situations would make the jeep very unstable and prone to flop on it's own suspension one way or the other, potentially flopping all the way over?
...but hey... I'm a relative newbie to the Jeep off road world, maybe I just haven't been a part of those discussions?
