Thanks for the clarification, I have a '15 2WD Silverado CC SB with the LTZ Z71 package, it has the Rancho Shocks and I have noticed a bit more bounce than it used to have but I have 75k on her at this point.
I did find out one thing, at least in my case the bed created a ton of vibes.. once I put a bed cover on it the vibs calmed 90% bet if I put new shocks it would be smooth again
