I have a set of 295s on the way to mount on some H2 rims. Completely stock 2004.5 GMC 2500HD as of now so what will I have to do to fit them. From searching I assume green keys/torsion cranking, but I am not sure on:

bumper trimming
bumper moving
e-brake

Any help is appreciated!

I know there's a thread on moving the bumber forward, IIRC it's in do-it-yourself section. With the front trimming, that's the plastic front valance/spoiler.
The e-brake gets tied back so it's not bulging into inner fenderwell.

315's on my chevy.

Raised bars.

No green keys.

Trimmed bumper.

Tied back inner wheel well in several places. (Still have some minor rubbing)
Had wheel alignment done.
Silver center caps from the work trucks.
The color difference is not as bad as it looks like in these pic’s.
