I have a Cognito 2"-3" UCA leveling kit that I paid $530.00 for. It comes with new bolt in style upper ball joints, upper control arms with dual shock mounts,and I also purchased the shock extenders so you can run the factory shocks. I bought it for my 08 Duramax but it got totalled by a mini sized nissan before I got it on so its brand new and has the instructions. It says it will fit 01 and up 8 lug GM. I would love to use it on a trade toward a brand new Smarty S 03 for my 01 Cummins or anything else cool you may have for it. Please, no junk as I have previously stated this is brand new. Thanks. Oh yeah, the kit is here in Virginia with me.
