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

[Eric Witte]

Trying to determine if a 2023 Sierra 1500 Denali Ultimate with super cruise control can be lifted.   would lift it 3.5" to 4"max.  Does anyone know if a lift will interfere with the super cruise control functionality?

[newdude]

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.

3.5" rough country lift with 285-65r20 no problem with super cruise or anything else.

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 .

I have the same question but do not have super cruise…any concerns?  Also— Will it kill my 30mpg on my 3.0?

Hi, found this forum searching for the same answer. Went ahead and went forward with a 6” on a 24 Denali ultimate 1500 and super cruise works just fine after.

What brand lift did you go with?

[SinisterSS]

That was hurting my brain.

Looks good! So no issues with SC? 
 

What kit did you use?

No issues so far got 9000 miles on it now. I used the rough country 3.5 kit for the denali.
