Leveling kits? If so, let's see them.

[inquenciocha]

What up.  So I just purchased my 2020 2500hd AT4 and I'm looking to do a leveling kit. I did a little research and saw the keys are the same as the 2019 2500 for the Readylift 66-3011, 2 ¼ kit.  Anyone already do this?  I was also thinking of doing a 1in block on the rear just in case.

I ordered a fabtech before receiving my truck. I cancelled after talking to a couple guys who had them. They were the only one who listed one for the 2020s at that time. A couple guys told me they rode like shit, and one even removed it and is back to stock until a lift kit comes out. 

 

When I received my truck finally, I measured and my rake is only 1.25" from front to back. So not sure if my front is sitting higher than normal or what, but I'm not going with anything for the time being. My 35s and Methods get mounted on Wednesday, and will see how they fit then. If anything I will crank the stock keys a couple turns. 

 

I like a bit of rake since my truck still works hard, and I hate the look of a squated rear when loaded.

Good info. Yeah, I haven't heard anything from anyone as of yet.  I got my keys on sale from Amazon and purchased early.  It's a $140 gamble I guess.  Let me know how it goes Wednesday, I'd love to see it.  I personally just want to clear 35s anyway.

I don't think you can level without proper rebound travel without control arm or frame modifications.  There is a service rebound stop that would need to be modified or you will never get enough rebound travel.

I had a 2.5" level kit installed along with 1" blocks  in the rear.   I don't have an issue with the ride.

These 2020's don't have the rake that the old trucks do.  That 1.5" difference sure makes the truck look as if it is squatting with no load!

Looks great! Which kit did you go with?

The dealer, Dennis Dillion in Boise ID did the the level kit.  I picked it up about a month ago.   From what the accessory manager told me they installed keys from GM 2011-2019.   It was leveled with GM parts with the exception of the shocks and rear blocks.  Over all it rides pretty good.  I'm thinking go with 35x12.5R20 on 20x10 Hostile wheels.  If I get rubbing then I would add some front bumper spacers -- .5" to 1" spacers.

Were you able to fit those 35s on?

Yup fit perfect and not a single rub. Thinking 37s would have fit with a higher offset wheel. I may push them out another 1/2-1” that’s where the 35s may start to rub. I’d think another lower than a 0 offset may be getting close.

Remember though, I never leveled or touched the keys. I wanted to see how they fit perfectly stock to keep all my travel and they fit perfectly. Driving in my fields and cycling through the full suspension while turning over bumps and not a rub.

Have a 2018 Sierra 1500 Denali with MagnaRide... Installed SuspensionMaxx 2.5" front leveling kit and 33X12.50x22 Nitto Ridge Grapplers with 2" spacers all around.

The BFGoodrich KO2 35x12.5x20 tires are actually 34.5”. Stock tires on our truck is 34.1”. I was wondering if they’d fit. What’s the width of your tires?

I had 35” Toyo RTs on my last truck. Considering the KO2 due to all the towing I do and the fact I drive in the snow a couple weeks per season for snowboarding ( Utah, California, etc.)

What offset are your wheels?  Thinking of changing mine again.
