Ok, short answers please. If you had an 04TJ, 4" lift, 4.0 5speed, 33 in tires and the ever popular Dana 30/35 combo, which rear end would you go to; 44, super 35, or 8.8 Ford? It's a daily driver and 98% of the time it will have pavement under the tires. Probably have either 4.10 or 4.56 with at least a TruTrac. Maybe, MAYBE, go to 35 in tires someday. Also have to upgrade front with gears and maybe stronger axles. Oh, fergot to mention, money is a definite factor!! I'm not exactly a mechanic so all labor will increase cost. I know it's a big question with lots of variables, so don't 'overthink' it. Thanks.
