I have a 2500HD AT4 2022 and want to make the ride softer like the 1500 Denali. I've read Bilstein with Sulastic shackle for the rears are good. Someone else mentioned cognito torsion bar. I don't know what that is or with what that will help with. I'm fairly new to 2500HD pickups. I wanted to get feedback or suggestion from you guys as where I live, the dealers that modify cars usually have a preference to specific company brands and all they do is sell sell. Any help from you guys, I will appreciate it.
Thanks!
