Stock Height

[22 Denali]

I just picked up a 2020 Sierra 2500 HD Denali. I am trying to determine if it has a leveling kit installed. It has 285/60/20’s installed and I want to go back to stock 275/65/20’s. I would also prefer to be stock height. Anyone know stock height to wheel wells?

Thanks

Also, I should have mentioned, it’s the diesel.

1042 mm +/- 14 mm from ground to fender at 60 psi.  Front axle.

Somewhat tricky on an HD.  On a 1500 its real easy to spot leveling parts.  If it was done with the stock torsion keys, the bolts would be turned up 5-10 turns.  It could have aftermarket keys in it as well. 

 

I'd be looking for shock extenders as well, either mounted up top or at the bottom of the front shocks.  I'd check the rear for lift blocks as well.  

 

To turn it back to stock ride, I'd have an alignment done and have them set the Trim Height of the truck, or Z height.  That will let them set the front ride height within the stock range GM prefers.

Thank you guys for the info. In my novice mechanical abilities it doesn’t appear to have been altered. The bolts on the torsion keys however are not equal, should they be? The truck sits maybe a 1/2” lower in the front. I just don’t want to be squatted when I hook up the 5th wheel. (1605 lbs pin weight)

No, the bolts are usually never equal.  Driver side is typically higher because of the weight of the fuel tank and driver.

If the truck sits only 1/2 inch higher in the rear it has been altered. In the stock configuration it should be 2 plus inches higher in the back when unloaded. 
 

I have a 2021 3500hd cclb with stock suspension and wheels/tires. When I install my popup camper, which puts 1600 lbs on the rear axle and 100 on the front axle ( I weighed it), the rear drops about 2 inches. The rear is still about 1/2 inch higher than the front with the camper on. The overload springs are not engaged at that load, so a 2500 would be the same. 
 

if you are approximately level unloaded, your 1600 lb 5th wheel hitch load is going to cause your truck to be about 2 inches lower in the rear. It will be close to the stops at that point.

Thanks

I have an appointment at the dealer Monday to have it checked/returned to stock settings and aligned.
