Z72 suspension?
 

Okay, got a dumb question here. What is the difference between a Z71 and a Z72 suspension? Reason I ask is there is a Blazer for sale in my area that has a Z72 suspension and I don't know if there is a difference between the two. Oh and my Blazer has premium suspension and I can feel every little bump on the road but the bigger the bump the more I don't notice it speed bumps are hardly noticeable. It's supposed to ride like a luxury car, like a Mercedes is what the dealer said.

Z71 is the suspension package for full size trucks. I think you mean ZR2, which is the suspension package for the S10s
