how much are offroad parts (rear,front ends)

[DetroitDan]

4.56 gears are too low for what you want to do. I wouldn't even think of running them unless the tires were upwards of about a 37-38. 4.10s are good with 35s, and 3.73s will work. All the offroad mags tell you to overgear everything, but all they know is rock climbing Jeeps. You're on the right track, anything over 33s and light off road is enough to justify losing the wimpy half ton axles.
Don't panic, you don't have to do everything that's been mentioned, and you certainly don't need to do it all at once. A steering arm or drag link can correct the steering, you won't need crossover or anything fancy like that. You don't really need to do much to run 35s. Stock driveshafts will be fine with a 4 inch. I have tried the front shims for front propellor shaft alignment, but they tend to break and fall out, so don't bother. Won't need it for 4 inch anyway.

Personally I like a 4 inch suspension and 3 inch bodylift. I know a lot of people hate bodylifts, bu in my experience they are just repeating stuff they've heard on pirate4x4 and dont really know what they're talking about. I've done numerous bodylifts and never had a bit of trouble. They are cheap and beneficial in several ways. More clearance for tires, more height visually, allows room to clean the mud and frogs out after wheeling, doesn't alter the steering geometry. Doesn't alter the frame height for towing applications, and depending on your states lift laws bumper and frame height get measured, not the body. So it's 3 inches height that wont put you over the legal limit.

I've heard a bunch of stories that they are dangerous and cause the body to fall off. I suspect that if the body falls off then you didn't install the body lift right in the first place. I've owned them for years with wheeling and yanking and all kinds of conditions and they don't fall off. It's just a matter of tightening the bolts down properly, then rechecking it after a couple hundred miles.

Sorry for the rant. I just hate when everyone badmouths bodylifts when it contradicts much of what I know firsthand.
