2022 (refreshed) Sierra 1500 Denali - 2.5in Leveling Kit

[Vi Fjunk]

I didn't find a lot of photos on this when I was doing research, but here's the before and after on my 2022 Sierra Denali 6.2L 4x4. I had a Suspension Maxx 2.5in leveling kit installed with their 1.5" kit block in the rear. The pics show it with stock tires, but I'll probably go to 285's once I wear these out. 

 

Brief thoughts on my kit after install below:

 

• Ride is about the same on the highway.
• Braking seems a little different, but not concerning. Might address itself after the alignment is done at the dealer.
• Adaptive cruise still works as it did before
• Height roughly matches AT4/AT4X when parked next to them. (That was my goal)
• Only wish I'd added another half inch to an inch in the rear to have a little bit of rake. From certain angles it looks like the front is a tiny bit higher than the back, but may just be optics. 

 

Due to restricted size of attachments, the pics will be in two or three more posts.

2.5" is a lot on the front suspension, may or may not be good long term. 

 

That is exactly why you keep some rake in it. The front ends of these trucks are so large these days that when it measures level it still appears nose high and only gets worse with any weight in the bed or on the hitch. 

 

Good thing you covered your license plate so no one can find you!

The guy's at the dealer and the shop that did it didn't flinch much, for better or for worse. I hope it's not too bad mid term. I wanted the AT4 height or at least something closer to an HD setup with the least modifications and impact on ride quality. 

 

Anyway, came from the HD 3/4 ton world, and this 1/2 ton suits 90% of what I'll be using this truck for, but I may end up back in the HD after having done my first 7,500 lb tow. In fact, I was talking to the sales guy about getting on the list for the refreshed 2024 HD. I wish they had a 3/4 ton this size though, I just don't need an extra foot of bed, or extra stiff springs most of the time.

Does the Lane Keep Assist still function properly? Want to level my 22 SLT 2" in front but concerned about screwing up calibration on ACC and lane assist.

 

Thanks!!

I know I'm really late, but after 16k miles and daily use of ACC including multiple 1k trips, it still functions as it did pre-level.

Appreciate the info and pics....most post info but never the pics.....looking to do something to this affect but just concerned with minor issues like clunking.

That did develop around the last 1k miles. Honestly, I wasn't sure what it was, and I was about to have it diagnosed before deciding to trade it. I literally had the appointment setup the day before the trade, and ironically had a meeting come up where I had to cancel my appointment.  I'm not sure if maybe it was screws needing to be re-torqued or or not; and it wouldn't be fair for me to attribute it to the leveling kit without proper diagnosis. However, the leveling kit was the only modification I did to the truck; it had original wheel/tire setup. It went about 15k miles before getting to that. 

 

As I'm writing this, I was thinking about when the sound came up. The last couple of thousands miles were during an out of state project where I was crossing some railroad tracks at between 50-60mph 6x's a week. That could have loosened the bolts resulting in the clunking sound.
