Spun the diff on the tubes a while back, cut the spring perches, ran a bead around the tubes, put a support bracket on the center diff sides, built/installed a truss across top, realigned the driveshaft and rewelded purches.
Unless anyone on here has access to Ansys, I don't think you can say positively. It all depends on where and how you use it (That's what she said)... You can resarch what other peoiple have used, but I am not sure you will get a response that tells you to use it without any backing...
The axles I have seen (4 or 5 in the last 2 months) that were bent, had bent just outside the perches. These jeeps had 31"-35" tires on them, and did light to moderate trail and desert running. Personally, I like to see the truss extend out to the axles tubes where the tubes flange out to cover the type of bending I described.
Right now, I am using an 1-3/4 .120 DOM tube bent in the middle to span over the pumpkin and out to the flanges. Then I am using 1/4 plate and tying in the ends of the tube to the axle tubes, and the middle of the tube to the main part of the pumpkin. In the middle I am using 1 side of plate, and on the ends possibly 2 to sandwhich the DOM tube in.
