Adding a Suspension Lift on a 2023 Sierra Denali Ultimate with Super Cruise


Recommended Posts

Highly likely.  Super Cruise is designed to operate on a stock height truck and stock diameter tires, and then should account for something like trailer sag.  There are no reprogramming or calibrations to the system to tell the truck it has been raised because there is no factory lift kit that fits the Denali. 

 

Plus, Denali have the Adaptive Ride Control.  

 

Not an ideal truck to lift.

Unless you're making it a show truck (ie. 12" lift  and 40s and another 10 grand minimum) you're looking for headaches.

Except for it being on its roof! LOL, Sorry, I had to.

Good Morning,
 
As discussed on the phone, the vehicle cannot be lifted or leveled. The calibrations for the Super cruise system require the vehicle to be at as-built ride-height or the system may not function. If you have any questions or concerns, please reach out to me directly.
 
Sincerely,

That's what I thought. Too many things change when lifted .
