[QUOTE="machoheadgames, post: 438183, member: 18789"] The front spartan will be fine. Many like the spartan or positrax no slip up there. I would do a truetrac out back to complement the front locker which would give you a capable mix of traction. For gears, if you’re gonna stick to 31’s, I’d do 3.73. If there’s any chance of 32-33, I’d do 4.10. You will be doing about 3000 rpm at 70mph/110kmh with either of those setups. Jeep geared many TJ automatics with Dana 44’s to 3.73 in 30’s, so what you would be doing is no more crazy than a stock setup. The revs are highish, but that’s just life with a 3 speed. [/QUOTE]
