Looking to lift this new HC. Love the truck but want a 2” or 3” lift. GM site has a 2” lift that is warranted but the system won’t let me add after putting in my VIN. My assumption is because my car is not ZR2? Any suggestions as to what suspension I can add or components to gain the lift without voiding? I am coming from ‘13 with a BDS lift but don’t want to go that route, it is too aggressive for my needs.
