I bought a used '99 TJ a few years ago. I was told it had a 3" lift, but not what kind of lift it was. It looks like it has a budget boost lift on it, I'm guessing it's just a 2" lift since I have not seen any 3" BB. I had a 3" body lift installed about a year after I purchased the Jeep. Do I need a SYE and CV driveshaft? It has a 4.0 liter engine. 35" tires.
