3.5 RC On 2WD Yukon XL

[Kerrville15]

So, I’ve got a 2021 GMC Yukon SLT and really want to put a 3 1/2” rough country kit on it. Of course the website says it doesn’t work on GMC models, but does anyone have any experience with trying it to see if it works? I’ve seen the 2 inch kit work, but want to make sure before ordering. Thanks
