Question:

I have a 99 F350 super duty that has a leveling kit on it. I believe that it was raised 2.5 inches in the front but not sure about the back if it was lifted. i have heard that they lift the back when adding a leveling kit. I have 35 inch tires on the truck as well. I am wondering if I need to do anything special to add air bags to the truck? Like any spacers or anything? Thanks for the help

Not knowing if the rear was lifted does complicate it a little, but it's not the end of the world. What you will need to do to get the Firestone # F2550 installed and working properly will be to first install the brackets. You will then need to measure from the bottom of the top bracket and the top of the bottom bracket. The measurements listed below will then determine if a lift spacer is needed.

6 1/2 to 7 1/2 - # F2536
7 1/2 to 8 1/2 - # F2366
8 1/2 to 9 1/2 - # F2367
9 1/2 to 10 1/2 - # F2370
11 1/2 to 12 1/2 - # F2374
