suspension lift is 10000000000000000000000 time better. this is because a body lift simply lifts your body off the from instead of a suspension lift which moves your tires and axles away from the frame thus giving you more clearence. A body lift, anything over 2" will put extreme amounts of stress on your tub bolts because you have increased the length of the bolts holding your time to your frame. so when you turn corners it puts a hell of alotta stress on those bolts...suspension lift does nothing to the body, but rather the springs of the jeep, so your are still decreasing your stability to a point, but safety is really not a huge issue unless you do a 7" suspension lift with stock width axles. but 4" suspension lift should do you very nicely. 1 inch body lift...2 at the max, don't go to 3" body lift, its just asking for trouble.

32" BF M/T's with cragar rims
5" BDS springs, MORE greasable shackles, XJ driveshaft, AA SYE kit, RE SS brake lines. Bilstein 5150's, 255/70 valving all around, 14" travel in front, 10" in rear.

actually from a stability stand point a BL will be more stable than a susp lift because you're only moving the lighter part of the jeep higher, while most of the weight, ie frame/engine stays lower, keeping the center of gravity down. you're right about it stressing the mounts though.

the main advantage to a BL though is the price tag. the main point of any lift is to gain clearance for bigger tires to increase your ground clearance to your axles. frame to ground clearance is usually of secondary importance since it's so much higher. so really the BL is the better way to lift from that stand point. but there is a limit to how high you can go as mean pointed out. too much BL and your run the risk of your mounts shifting or punching through the tub entirely. also after about 2" it starts looking like crap. the other advantage to a susp lift is that it can replace worn out springs and shocks at the same time as giving you more clearance. in the end, i say moderation in all things. a little lift from a BL, some suspension, maybe a small shackle lift, etc. 2.5" springs, .5-1" shackles, 2" BL and if you still need more some TJ flares and you can easily clear 33's. if you need more than that, keep the 2.5" springs and go SOA. that's my plan (or at least it was before the new jeep).

Ya to a point but to be safe i would definitley go with the suspension lift !! I'd never go more than a 1" BL, like said before you're asking for trouble, plus suspension gets you WAY MORE articulation ( BL gets you none) just cuts down on your tire rub a little. Go w/ suspension !! You'll never regret it !!! well your pocket might a little

if you want you can save a little money by piecing together your own lift if you know all of the things you need. Or if you are looking for something small like you said, 2-2.5", it should cost you more then 600 bucks im thinking. To some extent i could agree with sentinal, but in the long run, you simply wouldn't trust the strength of the body lift over time, with all the stress on those bolts, you would want the highest grade possible and make sure you get URATHANE(dunno about spelling) spacers...they wont dry and crack as easily as others, and if you decide to go to the body lift, make sure the kit you buy doesn't simply add spacers to the existing ones but replaces the existing ones as well as add spacers. it would save you a headache when you notice your body sitting unevenly b/c some of your old stock spacers are cracked.
