Hard wheeling...do you need uniframe stiffening if you have EXO?

I've recently added an exo, but I've also recently noticed some (self-inflicted) uniframe damage around my rear bump stops and leaf spring mounts. Should I try to fortify the frame or will the cage take care of that? It's tied to to the front winch bumper, the rocker panel tube, and the rear home made bumber

I guess the question is...weld up the cracks, or go all out?

What sort of frame damage is present and where exactly is it located ? The structural soundness and strength of the exocage depends upon its design, and on how it tied into the uni-body structure. Are the mounting points/tie-ins reinforced ? What other types of strengthening/stiffening are installed such as receiver hitch or heavy duty transmission cross member/long arm mounts ? A question to ponder is if the exocage is adding strength and stiffness or if it is concentrating stresses at the mounting points. Why would you not want to install some of the avialable frame rail reinforcements ?

I'd definitely do frame stiffeners front to back if you wheel hard. Tie in your box steel rockers to the frame rails somewhere near A- and C- pillar areas. Also make sure you do something about the leaf spring mounts you mentioned. I suppose you're running long arms, so front LCA and UCA mounts on the uniframe aren't an issue.

IMO, there's no need to go overkill with the stiffeners; some use 1/4" L-section which is.. ..well.. retardedly heavy and unnecessary in most cases. When I had my XJs, there were multiple places where the unibody/ uniframe started to crack after only a couple years of wheeling. Good front & rear bumpers, box steel rockers and exo-cage do help, but they're not enough for hard trail use.

You've gone so far as to exo the thing, why would you not go all in with chassis reinforcement?

Not all that expensive and easier than what you've done to this point.

I just didn't know if it was overkill/unnecessary. I got my answer. Thanks!
