bolt on, not really. the limiting factor is the torsion bars, they really limit the travel. swap to coilovers and your at a good start. Dixon Bros makes a 4x4 kit: '97-03 F-150 4wd Long Travel Suspension Kit - Long Travel Suspensions - Dixon Bros Racing From what this guy says, he loves it: GFO Chase F150 aka "Roxanne" if your not a member on ^^that, do it. and do a lot of stalking, just watch out if you post like a noob they will treat you like a noob, but there are some nice people on there. Dixon Bros is the only company I know that make a 4x4 kit, most make 2wd since the amount of travel you want is the most, with 4x4 you dont get much.
you aint kidding man. some days its like this. i hate it lol. i get bored and need stuff to talk about.
i'm not too sure, probably not. i bought mine from a local audio store selling them. i just used an offroad light wiring kit from vatozone. since LED's use less power it works fine
