Front lift above 3 inch ull need trackbar, control arms or control arm brackets or both, shocks, swaybar endlinks ect. To me I like around 4.5 costs can vary 450-700 depends who u go with
I like skinny tire sizes like 32x10.5. ran 285/75/16s mt for awhile and hated them.
Liked the firestone mt good tread wear longer life and threw some mud. Ejection out of the tread is to me essential if it gets packed in
What's the point
