Yeah I was gonna wait till I got some more mods on it but I can give a brief run down. 01 sport (not sure which model) its the 3.0. I havent dug very deep into this truck yet to find out all the specs. I did just add 265/70/16 Nitto Terra Grapplers yesterday...and I love them. I think im gonna get those springs from KrzyDav to add 2" and torque the torsion bars a bit. I talked to my mechanic last night and he said it shouldnt be too bad to do. (I do most of the work until it gets to crazy special stuff) I will update my sig. after I crawl up under it...
