Levelling kit for my 06 2wd

[cubber]

Hey, y'all. I want to raise the front of my 06 GMC so it will be level (or close). I just don't want it to be nose up. I have leveled 4x4s with the coil spacers, and torsion bar cranking. Am I correct to assume that the spacers will work on my 2 wheel drive? Should I go with 1.5 or 2 inch? I was really wanting to lower this truck, at first, but I need to keep one vehicle that's not a scraper! Plus, I thought sort of a mild prerunner thing might be cool. Here's the truck, and thanks!
