I did the 1.25" body lift with my 2.5" coil lift to fit 33's comfortably. I don't know of its just me but my jeep seems to ride smoother since the lift was put on. It also doesn't shake to pieces when I hit this certain set of bumps anymore. My mechanic said it drove like a Cadillac compared to his 4cyl TJ with stock gearing with a 6" lift and 35" boggers lol.
Edit: also I didn't have to do the tcase drop, all of my driveline angles are nearly horizontal.
