 My truck was only 1 and 1/4” higher in the rear than the front, stock. I kept mine pretty simple, I dialed in an inch on the front. That took out most of the rake. But didn’t put it dead level. 

 

I like my tread blocks flush with the fender and not sticking beyond. I went with a 20x9 +12 wheel and a 295/65/20 tire. That tire measures 35.3” tall. Which puts it right in between a 35 and 37. Tires labeled 35, typically measure in mid 34” range and tires labeled 37 typically measure in mid 36” range. 

 

I have zero rub. Off road at full lock, I would expect some fender liner rub. But have not encountered it yet.

Nice looking truck, what wheels do you have?

Thank you. The wheels are some inexpensive wheels from Vision. Vision Turbine

Would you be able to post some more pictures as I would like to see how far they stick out from the fender well?

These are 20x9 +12. I had tried to stay with a 20x9 +18. I just had a hard time finding a wheel that fit my tastes. I wasn’t looking for a black or a chrome wheel. So the choices start getting limited.

Change your taste, you’ll have more options ;) jk! Yeah outside of black or chrome the options are much more limited!

Update: Monday I will be getting my chrome Fuel Contra 22x10 on Nitto Trail Grapplers 35x12.50x22. I wanted to keep the ride quality so I was going to get a leveling kit with the arms and shocks but surprise they don't make a kit like that for a Denali with Magneride yet. Arg I guess I will be adding the arms and other components as they are released but for now I guess my ride will suffer a little. I will post pics as soon as I get it done.

Well it appears I have been lied to because after more research it appears that my Denali does not have Magneride.

According to a press release GM replaced Magneride with active damper shocks. Although a post from MTU Alum on Dec 31 2019 stated that "none of the HD trucks have active dampers" but even my build sheet does not say Magneride it only says Rancho Shocks as it has the Z71 package. The press release speaks about the 2019 I assume it's the same for 2020

 

2019 Sierra Denali: Adaptive Ride Control Replaces MagneRide

When it launches later this year, the 2019 Sierra Denali will feature a new suspension control technology called Adaptive Ride Control (ARC).

GMC tells us that ARC delivers “premium driving refinement with exceptional responsiveness”, with “a high level of primary vehicle motion control, but with better ride isolation”. The system consists of three components:

  1. Active dampers that are individually controlled every two milliseconds in a continuous range between the softest and firmest damping
  2. Relative wheel-to-body position sensors at each wheel
  3. A dedicated control unit with integrated sensors that detect heave, pitch and body roll motion

Damping is adjusted at each individual wheel when the Sierra is cornering, braking and accelerating, and damping rates will change when Sport mode is selected by the driver, or automatically when the system detects heavy trailers or large payloads.

Not Magnetic Ride Control

Don’t let the name fool you: Adaptive Ride Control (GM RPO code Z45) is not just another name for GM’s incredible Magnetic Ride Control, since ARC does not use magnetic dampers/magneto-rheological fluid. Instead, it uses different (and perhaps less sophisticated) active dampers.

Think of Adaptive Ride Control as Magnetic Ride Control “light”. Another way to look at it is that of a version of Continuous Damping Control, which is available on GM cars like the Buick Regal and LaCrosse and crossovers like the Buick Enclave, Cadillac XT4 and XT5, as well as the GMC Acadia, but adapted for the requirements of a pickup truck.

Just did this....

3+1 kit 

20X9 0 offset wheels

35X12.50X20 Ridge Grapplers

I get a slight rub when backing up with steering turned. It rubs the liner material inside the wheel well, but I think it can be easily fixed as the liner has some play and I should be able to somehow move it away a couple of inches.....I just need to investigate more to see how I would fasten it to keep it back to where the tire clears.

Looks awesome!  Is that the Rough Country?

on gm website for 2020 2500ds it shows height of at4 and Denali as the same. I know the 1500 at4 has a factory lift. Some pics look like 2500 at4 is taller than Denali. Anyone know for sure?

no offense- but for the 100th time .  on the 2500HD - there is no difference in heights on at4 vs denali - ONLY 1500's

My AT 4 also done at Dennis Dillon dealership in idaho, where I took delivery of my at4 dec 16... 2.5" +1" level kit with fox shocks, 35x12.5 R20 BFG TKO2 tires... the first pic shows the difference between the rest on the Lotd75df0778239fa50709132a0432c86ba.jpg99c46173f8ee15555abfe8e61d679e90.jpg5fd8f76eda618ac7c6e86f9969cd6f5f.jpg19248dbfb6c2bf0b20548e35b54f9ad3.jpge746e8b2582c58b91377d6cfbf8bb956.jpga7d3f8302fa58d56d5c4ed3ae8755bed.jpg3c717e52e2707e5592a8b9fa37f92205.jpg

No offense taken. Just seeing this picture the at4 looks taller than denali at the lot and wanted to confirm. But now re reading the post the level was already don’t so yes, it is taller in the pic

So you're telling me there's a chance!

 

haha sorry, had to ? Yeah it's surprising how much confusion that topic has caused with the 1500's being the only one with the added AT4 height.

    • Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks
    • My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.
    • I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing. 
    • get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.
    • This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
