    Coming from Navigator...what should I buy? Denali Ultimate vs escalade??

    I have both, a 21 Escalade and a 23 Ultimate. Both have exact same drivetrain and suspension. Escalade: I hate the shifter. The only thing I dislike is the center console. The shifter takes up to much room and leaves very little storage space. Things I love. The center cooler works great. I...

    Added Charging module to Constrained 2023 Ultimate

    My 2023 Ultimate with sliding console came without the phone charger. If you have one of these and lift the rubber mat console and see a module that says "Not Functional" it is not that hard to install the fix. Maybe about an hours labor. Total cost for the 2 items about $150. You first need...

    New Here / First Thread / First Mods (Yukon XL Denali)

    I install a catch can soon after I purchase these vehicles. I feel the biggest help will be after you get some miles on them it helps the intake valves from getting a buildup of burnt oil on them. This will help with the rough idle issue over time. I cured the rough idle issue on my 2017 Denali...

    21 suburban 2wd rear end fluid capacity

    I had an axle recall on my 21 Escalade. The dealership got the part and told me to bring it in. I had to wait over a week because they did not know that the rear end needed (special) fluid only available from gm. Their service bulletin did not say that. Unfortunately it could not be shipped next...

    2015 Tahoe. Oil in cylinder 6 after lifter replacement

    I was under the impression you had to do a cam change if you did not put the AFM lifters back in.

    2023 Yukon Denali Ultimate mystery codes

    I am a firm believer that whenever lifters are replaced that the vlom needs replacing also. I had lifters changed 3 times in a 2017 denali. Vehicle had just over 68,000 miles. I paid over 8 grand the first time. The 2nd time it registered just over 1200 miles. The 3rd time just over 1200 miles...

    Escalade side mirrors on a Tahoe LTZ!

    Has anyone tried the Trail Ridge tow mirrors? They look like they have everything except the power fold, which I don't really care about. This would be for my 2017 Yukon Denali. https://www.1aauto.com/2015-17-mirror-pair-trail-ridge-tr00393/i/1amrp01964
