    285/60R20 BFG AT KO2’s on my Yukon AT4: fit remarks

    I did a lot of research to see what was needed to mount these tires on my stock 20” rims, on my Yukon XL AT4 (air suspension). I did use the Westcott Designs fender liner pullback kit with great success as there’s no rubbing at the rear of the fender liner after doing the mod and the front...

    I “AT4-XL’ed” my Denali with one simple trick!

    The whole process only took 2.5 months and here’s how it looks! That’s my 22 Denali short wheelbase on the right, which I traded in, and my XL AT4 on the left. A few immediate things that stand out: -WOW, does the XL ever ride truly sublime (this one has magnetic ride and adaptive air...

    21+ Yukon floor jack pad: what’s compatible for rear jack point/“socket:”

    I need to jack up my 22’ Denali and the strange round “socket” shaped rear jack point is way small and awkward to get my floor jack any purchase. Is there an aftermarket tip or pad that is made to interface into that area? TIA!

    I had A BUNCH of My GMC Rewards points burning a hole in my pocket and finally found a use for them after the GMC Accessories website offered 20% off wheels and wheel accessories. I have a set of OEM AT4 rims on which I have been swapping a set of outrageous (at least on my Denali) looking...

    2022 Yukon Denali 6.2: beat my all-time high MPG!

    I was traveling over the weekend with the wife, two kids, my German Shorthair and a truck full of luggage. Coming back home from the in-laws, I was working on keeping my speed around 70 MPH on the interstate with the cruise set. We had some extreme tailwind (20+ MPH) and I was shocked to hit...

    Swapping exhaust on a Denali 6.2: who here kept their old one/how?

    I’m swapping the exhaust on my 22 Denali and wish to keep the factory exhaust should I decide the GM Performance exhaust is not for me. The dealer said they’re not sure how they can do that as the factory exhaust is so long they’re unsure how I’d transport it. I asked if it’s as simple as...

    Shudder from a stop to a slow start, then foot off gas?

    I discovered a potential issue while I’m in AWD in my 21 Yukon Denali. While slowly rolling to a stop sign in a row of cars, I was giving it slight gas then quickly taking my foot off the pedal. There was a noticeable shutter in the drivetrain and/or transmission. Anyone here feel this before...

    13k miles, and engine failure 400 miles away from home!

    Well it happened to me: my 2021 Yukon Denali 6.2L has what I’m 99.999% sure is lifter failure at 13,000 miles leaving me stranded in the UP of Michigan, almost 400 miles from home. I’m across the street from a Chevy/GMC dealership, thank god, and will find out my fate in the morning. For those...

    DIY rim swappers: what’s your preferred floor jack, other tools?

    I’m looking at buying a floor jack, torque wrench and any other necessary items to swap my rims back and forth from my summer set to off-road set/ winter set and curious what you all use. This won’t be to mount new tires on the rims but to swap complete sets on and off. TIA!

    Has anyone looked into mounting a light bar?

    I was thinking about mounting a Rigid Industries light bar on my 2021 Denali and wondered if any here have either mounted one or explored doing so. Photos would be a bonus if you did!

    Horn sounds 3 times upon starting: Anyone else experiencing this?

    Periodically I will climb in my Yukon, close the door and press the start button with the key fob in my pocket. The horn will beep 3 times in quick succession then the vehicle will start. I can't figure out what's going on here, and wondering if the vehicle isn't recognizing my key fob or if...

    Will 2020 Sierra AT4 18” rims fit?

    I’m looking to buy a set of dedicated off-road rims and tires for my upcoming 2021 Yukon Denali and from everything I’ve read, it appears the 18 and 20 inch rims from the 1500 Sierras would be compatible. Does anyone here know definitively if that’s the case? How about the TPMS: are they...

    The wait begins... 2021 Denali ordered!

    I was going back and forth, and back and forth... and, well you get the idea, on waiting GMC out to where they allow a second row bench to be ordered without a sunroof. I finally caved and put in an order yesterday with the damn sunroof. The timing is such that I need to have this vehicle...
