Stiffer for sure! The old school Chevy techs I used to work with are die hard Z71 fans originally told me about it. Also, I have a Z71 and my brother has the LTZ, both suburban and both with 5100’s, and his is a LOT softer than mine. I don’t have the actual numbers unfortunately.
Installed bilstein 5100s and rear Z71 springs
