I’m working through the same decision process currently. I will be inheriting an 05 TJ that my grandfather used to pull behind his motorhome. He had e lockers put in the Dana 30/35 axles but did not change anything else (no lift/tires). There was an issue with the rear locker not fully disengaging so he had it pulled out and the open center put back in.
The wiring remains, as does the d30 front locker, so i can put a locker back in with somewhat minimal extra work. The rear end is making a terrible noise as is so it needs work anyways.
From what I read on the wrangler forums, the super 35 kit, which swaps in a 30 spline locker center section and axles, and replace the outer bearing to match, is the same strength as a stock Dana 44, it just doesn’t fix the c-clip issue. According to info there, a super 35 is good for up to 35” tires.
