with my setup in this write up, i gained just under 3" of height. what height you get will depend on a few variables:
if you have 4WD, you will not be able to TT your front end more than 2" without a high risk of compromising your CV joints. so if you are 4WD, dont TT more than 2"! i have a 2WD so i cranked those babies up to well over 2".
also, i was able to net 3" of height from the rear end just by changing to warrior 153 shackles. i have heard of other forum members using the same shackles and netting anywhere between 1.75" - 3.0. it may have to do with how your springs react to the new taller shackles you will be installing, you will also have serious lift the first day you install the shackles, and then it will settle overnight or after a few drives to something a little more permanent. i remember getting over 3" just from the shackles, and then they settled in and i got just under 3" of lift in the rear.
there are plenty of forum members who also run rancho RS5000's, and have anywhere from stock to 5" lift height and they are running just fine.
oh, and NO body lift on my trac. i fit the 33"s with just a simple TT/shackle lift and some moderate trimming. yes it can be done and can be fully functional on the trail and in the city. just take a look at the link in my signature and you will see what i mean.
