my brother has a 2007 tahoe that be bought from someone after an accident so he took it to a shop it have the frame straightened out and body work done. at the same time he converted to standard shocks. at 200k miles his tahoe drives like a million bucks. my 2011 Denali 120k miles z55 suspension feels like shit compared to his. does the z55 suspension go bad over time or is it one a shock blows then replace? is it only cause his is brand new? just recently had the brakes changed so I had the shop look over the suspension and they said everything was fine.
