This is my first post here after trolling for about a month. Bought an 03 LTZ for my daughter. She likes the TB because it's like a small Suburban. Has about 140k with original black Bilsteins. Just install the HD Bilsteins and ball joints. Wow what a diffence in the ride. Thank you for all the great info on this site. I'll be trolling much more as I make it better and better.
