Ok i clearly have an 03 truck which means i have leafs. So my question is, What is the biggest wheel tire combo i can run with a leveling kit and i plan to put new shocks on the truck as well! As well as backspace. I would like to get fairly deep wheels in 18's or 20's with like 33/12.50's Iam open for suggestions on brands of levels and shocks as well! Thanks for the help!
