To the op
1 8.25 is a great axle I have had mine in my rig for a year and have been wheeling on it no problems. This is with a auto locker in it.
2 shocks matter for ride, with my rubicon express springs I have a great ride with my 255/75 valved bilstien 5150s
3 keep it 2-3 inches a 33 will fit no problem!
4 I have an auto, but 3.55s on my mtrs was not bad. On the heavier steel rims and with heavier swampers I need gears bad.
5 steering. I have a zj tie rod it is a nice setup. But currie is better.
6 body. Factory skids are not bad! Grab them! Do unibody stiffeners as well!
That's all for now folks!
