Will a little bumper spacing you will be able to fit the larger tires.

Tuff Country makes the kit you want. I had it installed on my truck for roughly 2 years before I switched to the RSK. The reason I switched is the ride is pretty rough with that multi leaf pak installed under an already stiff leaf spring. If you purchase just the 2.5 inch brackets and install the 3 inch RSK form Sky it will give you the desired lift you want and will still ride like your stock truck since you retain your stock springs. I run 295x75x16 BFG AT's and have know problems. Just thought you might be interested in another option. Good luck
7.3 Stroker; Installing the RSK on an D50 TTB truck is a very easy task. All you need to do is replace the factory drop brackets with the 2.5 inch ones form tuff country and install the RSK the way you would on any F350 and your done; minus a good alignment of course. When I did mine I replaced the springs with new factory replacements form JC Whitney since mine had about 100k on them. I will try to post some pics tonight.
7.3 Stroker; I do not have the part #'s to the springs, but if you go their website just order the heavy duty front 2 pak springs for the 80-96 f250. I attached some photos tonight in the members gallery. Just do a search for me "mag7rht" and that should take you there.
