The ICON Collar is for the front only. The 1.5 inch setting will level the front with the back. The Deavers I put on are are the same height for the rear as the factory springs. My understanding is if you go with the Geiser springs the front will be about 1 inch taller than the rear at the factory rear height. Deaver has a spring that is 1 inch over standard height that you may want to consider if you go with the Geiser Front Springs. If you do the Geiser I think you'll also want to go with 37's. The 35's will look small with he front raised that much. Just my opinion. Good luck.
