104 TJ rear springs get you close to 4.5 inches of lift in the rear. I had the Eibach springs which lifted it 1.5 incheas in the rear and when I compared the Eibach springs to the TJ springs I gained an additional 3 inches over the Eibach springs. This is not gained by just the increased spring rates. The coils are that much taller.
