the only thing I have found is stock height fox or some other variant replacement shocks. other then that I would go drive a 3500 dually and then come back and enjoy the ride of your truck lol. sorry man.
I'm going to have to crawl under my truck and check that out. I know the Z71's ride a little rougher, as expected, but I find it annoying on the stutter type bumps. I wish I could get some Old Man Emu shocks for my truck like I have on my Jeep. They are awesome!
Maybe not exactly what the OP is referring to but just my 0.02
'16 Canyon SLT 4X4 , not Z71. Rides like a truck again not like the full size Silverado/ Sierra w/ the Cadillac-like ride. Empty, the rear catches expansion joints, potholes and bumps like trucks of old, front not so much. The rear got a little squirrelly nailing the throttle out of a intersection to beat traffic. Not a deal killer tho. I think the rear is sprung heavier like it feels having to do w/ tow capacity.
For winter driving ballast I put 200# of sand bags in the rear behind a 2X6 in the factory bedliner slot. Really smoothed the ride out, still rides like a truck just not as much 'old school' truck.
For the front, taking notes here and waiting till spring to decide on a leveling kit. Shocks my be an option down the road too.
