2015 Z71 Rides Bad After multiple Lift/Leveling Kits

A few years ago I installed a Rough Country 3” lift with lift struts and new A arms. I put 35” tires on it with no issues except the rough ride. I decided to buy the KYB struts and leveling blocks, new NAPA A arms, and KYB shocks for the rear in an attempt smooth out the ride. I also put a set of 275/70-18 BFG AT’s on it when I took the RC lift off. The truck rides straight down the highway but even hitting small bumps it still rides rough. I’m at a loss and looking for advice on what I need to do to get the factory ride back.

As far as your tires, are they LT tires because those are going to have stiffer sidewalls and as a result, a much stiffer ride.

I put a set of tires and rims off of a new Z71 on it before I removed the RC lift and it didn’t help the rough ride.
