Same jeep as you.
37x12.50 GY MTR's for 30,000+kms and than/now 37x14.50 Toyo OC MT's.
5.13's made HUGE difference. i ran thousands of kms with 4.10's and it worked but 5.13's really made it night and day.
i upgraded all shafts to Superior Chromolly.
i broke a stock front shaft doing NOTHING!
i also broke a Superior in a rockcrawl comp and it was replaced free the next day. It never broke again and i never entered comps again. lol.
i ran 5.5 +1.25 lift. i flatfendered it. It was too much lift. 5.5 was enough.
The swazall is the way to go. Save your money and spend it on an exocage setup as the 'fender'. i have been on my side 6x and other than broken mirrors, i have never had damage with that set-up.
i also was gentle. i hate mud. and technique with a well built jeep overcomes 'pedal to the metal' everytime.
