What is your main use of the vehicle? Does it see lots of street use?
I agree, body lifts should only be used as a last resort for that little bit of clearance you need for (example) motor swaps, etc. or to accompany a quality suspension lift of sorts. I don't like them but lots of people on here run them successfully as their primary mode of lift. Your choice. If you're looking for a super cheap way to just make it look taller, do what you want to do.
On the other hand, another cost effective solution, I don't even like shackle lifts but I'd recommend them over a body lift.
x2 what JLuck said about the shifters...the Samurai shifters are really affected by this.
If you want to spend a little more, do a shackle reversal. You could make it yourself, or use Calmini's kit
