2002 Envoy. 4x4. Stock suspension, stock tires. Just want to level it out to give me a little more clearance up front. It has 4600 Bilstein schocks on the rear. I'm planning on putting the adjustable 5100's in the front. The 5100 go up to 2.5 inches of lift IIRC. How much would just level it out? Thanks for any info.
