So I will have a 3 1/2" lift installed on my 90 xj 4.0L and it will have shims installed for the vibration. The lift consist of coil in front and AAL in the rear Now If I add another inch, am I going to have issues with vibration?????? the extra lift will be shackle in rear maybe a full leaf, and spacer up front.
