There are only certian ways to lift a Jeep.
Body lift, which you already have.
Suspension lift. This is by far the best way to lift your rig. You have several options here. The lift size range from 1.5 add-a-leaf, to 4.5" lifts. The higher you go, the more money you soend on the lift and Mods.
Then there is the the ever popular (cheaper) shakle lift. Alot of people will say to stay away from these, and I agree. They doo offer up to 1.5" of lift but they flatten your springs, decrease your front end clearance. However, some people like than and recommend them.
My recommendation would be to save some money and buy a suspension lift. TO fit 33" rubber under you rjeep you will need atleast 3.5" of lift (+ you 2" body lift). By adding the suspension lift, you will be lifting your jeep right. As many on this board will tell you, if you are going to do it right, do it the first time. You will save yourself some headaches and money in the long run.
Recommendations on lifts. 3.5" BDS, 4.5" Rubicon Express, 4" ProComp, and 3.5" Superlift are all good lifts. They range from $500 to $900. Some on this board are running Tough Country 3.5" lift and love it. They run about $350-450.
Hope all of this helps in your decision process. Goiod luck.
