Buying 2018 2500 Denali w 25K Miles - Question Re Z71

[sgnden]

After looking at many, many, 2018-2019 GMC 2500 Denali trucks, I found a local private party with a MINT condition example with 25K miles. They guy still has the protective film on the buttons and screen, obsessively clean fellow.  Completely stock. Excited to close the deal tomorrow.

 

The only option it does not have is the Z71 package. With 1/2 ton trucks that I can actually get into tough off road situations, the Hill Decent Control proved to be very handy.  Is this something that can be added since it leverages the cruise and anti-lock brakes?  I realize that it won't have the off road pitch/roll in the display.

 

I'll put a level / small lift (2") and add skid plates assuming they aren't there since there's no Z71.

 

Thanks!

2019 HD Denali the skid plates are standard.

NZZ    Underbody Shield, frame-mounted shields, includes front underbody shield starting behind front bumper and running to first cross-member, protecting front underbody, oil pan, differential case and transfer case

Z71         Suspension Package, Off-Road, requires 4WD models, includes twin tube Rancho brand shocks and (JHD) Hill Descent Control
1 -  Requires all-terrain tires. Z71 chrome front fender emblem not included on Denali models. 

 

I'm not 100% positive, but I think that 2018 Denali 2500 NZZ and Z71 were the same as above

All 4WD truck have the Off Road display - it is not activated from the factory however you can select it from many available screens in the DIC.

 

Skid plates can be added if needed - as for the Hill Decent control I am not sure if it is something that can be programmed in or not. I know that there is a need for a switch to activate it.
