    I want to know specifics on the spring rates vs standard a d vs denali w/ mag ride. Same with sway bars that are suppose to bigger and higher rates, but by how much?

    Help: Does the 6.2L have Fuel Management (AFM/DFM)?

    You can watch tach jump periodically when the condition are right. I can feel every transition my 21 xl denali makes

    2021 Denali OTA updates

    I have a 2021 Yukon XL Denali with 9/21 build date. Those of you with a similar build date, have you received any ATO updates since about December of 2021? Dealer I took it to and asked the question said no, but I question the effort the put into the answer.

    Global B architecture cracked

    But in that press release they also said that it cost 5k to modify the physical ECM to even access it, plus with Global B or as GM calls it VIP architecture the security is Per VIN Based and trifecta stated that they have only accessed the 1 C8. So even though they cracked the first one, there...

    2022 Z71 Tahoe Transmission Rough Shifting

    6.2L V8 - 2021 owners

I run 39-40psi tire pressure, and have changed oil twice since new in 3k miles. Oil is cheap, 91 octane is reasonably cheap. Engine...

    Phoenix area dealers

    To Hell will Phoenix area dealers. STAY FAR AWAY from Earnhardt dealers, we stupidly paid 10k over on a 21 XL Denali last December and was the only one left in the state with rear seat entertainment. I was looking at 3500HD Denali Dually recently and found a dealer on the north side of Las Vegas...

    Question re: Yukon AT4 stock tire & wheel weight

    my best guess without pulling a wheel off and grabbing the bathroom scale is about 60-70lbs. OE wheels usually are not light, and big light truck tires range from 35- 45lbs depending on brand and specifics.

I already read through the PDF docs on the specs of the vehicle, but not a lot of specifics other than 35mm solid front sway bar and 32mm hollow rear sway bar with 22mm lower right height over civilian tahoe. Thanks in...
