Hey guys,gals, I bought my fathers 2003 silverado 5.3L Z71 last summer. Awesome truck. I decided to join a forum to get some advice/opinions on a few projects i have planned for the summer. Not really looking to "pimp it out", just some simple upgrades and general maintenance(just passed the 120,000 mile marker). I'm a big do-it-yourselfer so i expect you guys will come in handy. Keep your eyes out for my upcoming posts: front suspension leveling kit questions rear differential maintenance ext... look forward to talking with you guys. cheers!
