X Stock Axels
I have stock Dana 30 and Dana 44 on my unlimited X stuffed with 5.13 and Auburn ECTED lockers front and rear. I am currently running 35x12.5 Mickey Thompson Baja MTZ’s. I was wondering what would be the biggest tire size I could run. And if I put chromoly axle shafts would that make them strong enough to run an even larger tire.

what shafts did you go with?

The problem with the D30 is not the shafts it's the small Ring and Pinion (R&P). Your locker already took care of one of the week links, the carrier / spider gears. The next week link is the shafts. When you upgrade the shafts the week link in your setup will be the R&P. The small D30 R&P combined with your gearing makes you R&P particularly vulnerable to breakage as the higher you gear the thinner and weaker the R&P teeth become. If you go 37s as is you may break shafts. If you upgrade the shafts and run 37s you may break the R&P and if you break the R&P your whole investment in the axle may go up in a flying mess of metal shards.
