Stock LSD or Tru-Trac?
I'm on deployment right now (it's more of a vacation with per diem this time, my last one was on a boat), and when I come home, I figure I'll have enough money to pay my Jeep off and regear it. I'm thinking of going to 4.10 to not destroy the D30's R&P with a front Tru-Trac. My question is it worth it to upgrade the factory rear LSD to a Tru-Trac? I don't know whether the stock one is gear driven or has a clutch pack. If I have enough I may end up getting a D44 for the front and go to 4.56 with a locker, maybe 37s. I'm not decided on whether I want a locker in the rear or keep an LSD for street driving if I go that route. I'm waiting to make that decision because I was talking to the Spicer rep at the Bantam Jeep Fest, and he said they were working on maybe releasing an Ultimate front D44.
My Jeep: '13 2dr, 3.6 manual, 35s (34.25 after about 12k miles), 3.73s. Drives ok here in the Lowcountry because it's flat, but I get out in a year and a half and am probably going back to Arizona where there's a lot more mountains or maybe Texas.

The factory limited is clutch-based. If you plan to offroad it, a gear-driven truetrac would be the better option.
But, you need to decide on the 44 upgrade first. You might look for a set of take-off rubi axles. (newer rubi's have a choice between 3.73 and 4.10, so verify the ratio). Aftermarket 44's are pricey enough that you might skip them and look at a front 60 or a junkyard build instead. And if you are really considering 37's, this would probably be a much better route to go than dumping money into a 30.
Also, if you stay with either of the stock front housings, you should research the various forms of reinforcement.
