Personally I think you defeated what the truck was designed and built for, Kinda went backwards, But its yours and you can do what you want to it, and with the little info in your post, you might have a few things to look into, 1- Might have to go higher, 2-tire size and rim offset/back spacing, for the lift, beside the flack your gonna get, I sure there are some on the forum that will be of help. GOOD LUCK.
