I have a 2000 Z71 and mine sat slightly lower in the front. I took it to an alignment shop and had them tighten my torsion bars and realigning the front end. Ended up raising the front end about 1.5 inches and now the truck looks level. I like it a lot better also, it looks really good. Costed about $75 for the operation which is cheap compared to getting any suspension lifts.
