You can get Auto Level control, but all that does is raise the rear end if it sags due to passengers or a trailer. They sit high. Your only option is to either lower or add aftermarket air bags with auto level control. Auto Ride/Smooth ride is real time shock damping that automatically softens or firms up the shock valves based on road conditions, it does work nicely. Had it on my 04 Denali, but not available on the Z71's. I miss both AutoLevel and AutoRide control, if I had it to do over I would have gotten an LTZ or another Denali, oh well maybe next year.
