    Cylinder deactivation for the 2021-2023's?

    Yes, absolute game changer. I make no promises it’ll help from a reliability/longevity standpoint for the motor, but man does it drive better. I didn’t like the transmission behavior in L9 so seldom used that trick. Felt sluggish to me.

    Cylinder deactivation for the 2021-2023's?

    Range is just about there, I’m beta testing their device as we speak. It’s not quite as simple as the OBD plug in, it connects directly to the ECM right behind the driver side fender liner. I can say my 5.3 drives WAY smoother now, no more lugging.

    What did you do to your 21+ T1XX today?

    So the question is…. After all that hard work does she like it? I did the same, but black tips.

    You do need higher pressure because you went from SL’s to LT’s for proper load carrying. Cupping, don’t know about that, and 50 psi sounds high, but in the 40’s is typical. These guys made it easy so you don’t have to look up the new pressure on a load chart...

    2022 Yukon AT4 with Thule cross bars

    @iggy3773 I know this is an old post, so not sure if you're still monitoring. But... if you are and feel like doing a favor, can you get a dimension from the top of the roof rail to to the top of the cross rail foot? Or roof to top of cross rail. I know this system is lower than OEM (which is...

    2023 Stock Z71 with 285/60R20

    As far as bang for the buck, I'd say the Rugged Trek's were the best of the bunch. All of them have their strengths, KO2's were super quiet, Duratrac's were amazing in the rain and snow, but rugged trek's seemed the most well rounded for my use.

    Gotcha, didn’t catch the Magneride part. My experience is with the 2” rc and 3” readylift, and I can say both of those are nose high on my z71 (more so with the RC). Pics I’ve seen show the same for the 3.5. With that said, trim packages other than z71 and at4 sit level or even a bit rear high...

    RC has a 2" with strut spacers, and a 3.5" with strut and preload spacers. You're asking if you can get the 3.5" but leave out the preload spacers, and only used the strut spacers and UCA's?

    2023 Stock Z71 with 285/60R20

    Thanks @IronWill42 , I'm not looking for the floating on the clouds type ride, just trying to have a tread pattern that doesn't have the vibration/nibble at highway speeds. No issue if I can "feel" the road, just don't want anything extra out of the tires. Might have to give them a shot.

    2023 Stock Z71 with 285/60R20

    Thanks @olyelr , they've been a consideration based on many good reviews, I’ve just had a hard time getting past the history. They were a budget tire made in Thailand, $100 less per tire than all of the competitors, Covid screws up importing, drives the price up and they’re the same tire but...

    2023 Stock Z71 with 285/60R20

    @IronWill42 I know this is an old post but wondering what you think of the at3 xlt’s with some miles? I’m most interested in highway feel between 65 mph - 75 mph if you’ve spent time there. I’ve run a lot different somewhat aggressive AT’s. BFG’s, Nitto’s, Toyo’s, Goodyears, Coopers (Rugged...

    I think you’ll get more relevant info in the 2015-2020 section. The 21-up are way different.

    Thanks for the info! Back of my front fenders has some space, did the wescott pull backs, but front of front fenders was rubbing with 295 60 20’s even after a little rework. So I’d have more to do there with 35’s. I use the Waze app to check speedometer. Had an mph app too which seemed the same...

    Was trimming/cutting pretty extreme for the 35’s? I’m on a 3” readylift and temptation to move up to 35’s is there. Speedometer 2-3 mph low?

    Doesn’t look like a 21-up to me.

    My ‘22 z71 has AC lines at the back of the front passenger side wheel well too, just above the frame. Something else to keep an eye on.

    Please get some pics of what your wheel wells look like after the trimming, it’s remarkable you could get that kind of offset working on a 3” lift with 33’s let alone 35’s. I give you a lot of credit, this has to be a lot of work!

    Looks amazing! Rubbing hard with that setup?? I’ve trimmed quite a bit with more lift and less tire

    sounds right, (2) per arm. It ends up being solid when everything is together, you'll be good!

    You're welcome. And yes, without the AMP powersteps the wife and kids would not be happy with my decision to go 3" LOL

    I gathered some info from some FB friends who have the 3.5" RC on the 21-up Tahoe group. One Z71 was 40.5" front / 40" rear, the other was 40" front / 40.5" rear. A bit perplexing, even with variables like amount of fuel in the tank at the time of measurement the differences are significant from...

    I just had the 2” RC removed and can measure the spacers if it helps you (upgraded to 3” readylift). With the 2” in my Z71 it was nose high. I believe that happens with both the 2” and 3.5” RC on z71 and at4, yet LS and LT Tahoe and SLE and SLT Yukons sit level or have a bit of rake with the...

    Probably not the struts, it’s the upper control arms that are hitting your wheels without the spacers. I’m running 2” RC, 1.25” spacers, stock size tires and had to remove the brackets behind the fender liners and do a little trimming. Did you remove the brackets?

    Lifted/Leveled 2021 - Postem Up

    That pull back kit is interesting. So after removing the gm supplied brackets behind the fender liners you bolt those new brackets up? I achieved the same thing with a hole and a zip tie, but that’s certainly a more legit way to do it.
