Hi everyone,
Signed up a while ago and have been lurking for a bit. I have a 2004 Sierra ext. cab 4x4 with a 4.8l. It has a 3" suspension lift, 285/70/17 on stock wheels, cold air intake, TBS, Pacesetter cat-back exhaust, and Superchips tuner. I plan to add a set of 22" wheels soon. This is a great resource, and I will have tons of questions I am sure.
