I have 2003 GMC Yukon Denali that I converted the rear air shocks to regular bilstein 4600 on the back and front. I also changed my rear coil springs as I was told. My ride is still bumpy. What can I do?

that's what happens when you convert that system often. it was designed for something else, you start changing things, often it ends up worse. I would leave it all stock myself
