97 GMC 1500 B/D with 22's question

I'm starting my body drop this week and i'm on 18's now but i'm going to get 22's. looking at some of the stuff on the fire wall it seems that some things are going to have to be moved and maybe the fire wall is going to have to be moded, but the question is can some one tell me all the stuff they did on their to make it all work out rightand stuff that you just put in the trash that i don't need any more. pictures will help. thanks

um, you need to gut your engine bay.

inner fenders, computers washer jug all that shit take it out.

cut two large holes in your firewall where your tires are going to hit it.

cut your wiring harness out, and move it over and up a lot.

i suggest buying the wheels when you do it, or at least get 1 wheel and a tire to do the mach up right, or, make one out of wood.


Also your steering linkage will hit your control arm.

its not going to hit if its only layin rocker.

yea i'm only going to the rocker

mine is 2.5". and it lays hard as piss, the bolts on the bottom of the fender are flat.

Here is a shot of the driver's side on my truck with a 3.25" body drop with a 29" tire. The pic is shitty, but it might give you a little insight on how much tire you are going to tuck. The tire sits right under the cruise control box. I see your truck has a manual tranny, so the clutch cylinder will probably need relocated along with other things like your ABS and fuse box. Glad mine is a '88 and I don't have that shit.
