Leveling kit for a 06 1500

[RED 1970]

I own a 70 K5 as well as a 2006 1500 4x4.
My problem is the pickup is a company vehicle, I work for a pretty sweet company that will allow me to do whatever I want to my vehicle however when they sell it whatever I put on goes along with it, so no high buck upgrades here just some small tweaks to make my commute a little more enjoyable.

I'm looking at getting a leveling kit of some sort to bring the front of the truck up a bit and well to be redundant, level the ride... I will not be fitting 40's or anything crazy like that, might move up to 33's if it is possible to get them in with no rubbing.

Who here has experience with or pictures of leveling kits?

Thanks for your help, if I get to figuring something out I'll post some before-after shots.
