Hey guys... I have previously bought a black 2007 SIlverado 1500 Z71 4x4 crew cab. I am looking to gain some insight and knowledge about lift kits, wheel/tire packages, and upgrades to get the most out of my truck. Any and all info helps. I am looking into 4-5" lift kits and 20' wheels with 35x12.50 tires. thanks and looking forward to it..
