probably could do it with a 1" drop kit - get intimate with a sawzall...
realisticaly with keeping the "normal" body lines and only cutting a little bit, a 4-4.5" is about the height to shop for...
but be prepared for Flames for "likeing the look of 33's" and not wanting to do anything driveline related (especialy if you have ABS)
the 4.5" if done correctly will require a new transfer case output - namely a Slip Yoke Eliminator and a new driveshaft.
get a kit that has the following:
Brake Lines
Adjustable Upper AND Lower control arms
Coils
Full rear spring packs
Adjsutable trackbar (HD style with new frame mount)
Bump Stops
Quick Disconecting front sway bar links
Shocks (and a steering stabilizer if yours is shot)
or you could re-think your goals and get the 3" kit and some 31" tires... - a good 3" kit has:
Coils, LCA's, Brake Lines, Leaf packs, swaybar disco's....
much cheaper and just as fun - with less axle brekaage and less replacing of the unit bearings on the d30....
