I am waiting to install my RE 3.5" lift on 2000 XJ. I was talking to someone else and he said that I am going to "definately" need a SYE for this lift and a 97+ XJ. Will I be ok with just a 1" T-case drop or should I go ahead and order the SYE? I am kind of hurting on funds and would rather not go with the SYE right now. The guy I was talking to said that he has a 2" BB on his 98 XJ and he needed a 1" t-case drop, so he said that I would definately need one with a 3.5" lift. Also, is the RE 3.5" lift a higher lift than all other ~3" lifts or is that just their trademark? Thanks for the info.
