Whats going on everybody, im Rob , i own a 2013 gmc sierra 1500 white diamond. Current mods are just rear lowering shackles, k&n intake and just HIDS heads & fogs. My future mods are to do an exhuast, headers, a tune, and to do the 2in drop spindles. So hopefully everything turns out ok at the end. Im a GM tech so if you have any questions let me know ill try my best to help you all out!
