Getting a 07 sierra reg cab short bed soon its stock and 22s, sits extremely high even asked him if it was lifted. I work at a apt complex so go over speed bumps a lot, I know the bumper sits lower than the rest of the truck so worried about hitting it. I had a ford lightning before it had a 3/5 drop I think and didn't hit the front but the tranny pan did get smashed.. I believe the frame sticks down lower on them though. So what drop would you recommend for me? Here are a couple pics of the truck and my old one for reference , thanks and hopefully will be posting a lot here!
