Gotta go pick this thing up Saturday and already looking at mods. What's the best option for lowering a 2wd a few inches? I want it to sit level too. Also are there any worthwhile fuel economy mods for the 5.3 and what kinda of mpg are you seeing with yours?

Only fuel economy mod I made on my '04 5.3 2WD is a K&N Cold Air Intake\Filter. I'm getting 16.5 on the dot....all city. I haven't taken it on the highway for any length of time.
