Thanks, so sounds like that base suspension is not a big step down from magnaride in terms of ride quality? I would also assume the introduction of IRS, if anything, is a bigger improvement for ride quality than magnaride over previous generations..

What about the air shocks? Are those just to control ride height or do they change the driving dynamics like on premium German cars? In both the current X7 as previous Audi's equipped with air suspension I found that to be the sweet spot and most noticeable between different driving modes (sport = stiffer / less body roll and comfort = more suspension travel to "glide" over the road)
The base suspension can feel like a "rock star" with the add on of Hellwig Sway Bar Kits, front and rear. I would expect them to come out with the kits soon after the design is perfected. My 05 Tahoe is completely stock suspension but I still amaze friends and even myself, as to the great handling improvements brought on by my front and rear Hellwig Sway Bar Kits. Other members here have them on as well.

The rear air shocks are just for leveling the rear of the vehicle. If it gets loaded down with people/cargo or a trailer, they will automatically air up and level the rear back off with the front. They have worked very well in the last few rigs we have had with it. Im a big fan of them.

Magnaride is not the air suspension/ride height changing suspension persay (although most do have air shocks in the back for leveling loads). The magnaride system is electronic shocks, which change dampening some thousands of times per second. If you get a model with magnaride, it will most likely be riding like shit within 50k or so anyway with locked up/blown out electronic shocks. Ask me (and zillions of other) how we know.

My wifes ‘22 tahoe high country, from what i can tell, does not have magnaride. It rides just as good, if not better than her ‘16 denali xl with magnaride.
All High Countrys have MRC.

Well shit. Where are the ride height sensors? Crawled around for a second on the floor and didnt see any.

Or ordered one of those cheap ass lower strut spacer 1.5” leveling kits but it doesnt have link entenders (like i needed with her denali). Is that still a needed component to keep magnaride happy?

Our '21 yukon has base suspension aka premium smooth ride suspension and it rides really really nice. It's super smooth and doesn't nose dive or have massive body roll or anything excessive. Definitely not losing any sleep over not having magneride or air.
A couple things I could not live without on this vehicle would be heated seats (seem to be standard equipment on most new cars) and these amazing led headlights. I'm not sure what the chevy has for lighting but damn the gmc headlights are fantastic.

I considered a baby duramax at first but after a bit of research decided that was not the engine for me. Way too much tech on an unproven platform. I suppose time will tell but these look designed to fail IMO

Only asking because am curious. What "looks to be designed to fail"? I know what you mean about the Duramax tech with the 6 cylinder but I had a Duramax 8 cylinder and was a fantastic engine. Again, I ask because I don't know, but since the engine has been around since 2019, is it the new Tahoe/Yukon platform that worries you or just the new tech on that engine?

It's more the engine than the platform that I don't like. They've crammed a lot of "this should work" things onto it and then put in a wet belt for the oil pump and sandwich it and the high pressure fuel pump between the transmission. Good thinking, lets pull the tranny to replace a belt. Most people know diesels love to run for extended periods of time and love to run hot so adding auto stop/start to this engine seems counterintuitive. And IMO they sound like ****. They sound like a badly misfiring gasser, or a 5.3 with lifter problems :eek:

The real duramax 6.6 engines on the other hand are awesome. Other than the early fuel injector problems these things are beast mode. I know lots of people that have them and love them

Well would you rather have a "Designed to fail" engine or one that is already actually failing? The problems and complaints in the 5.3 & 6.2 forums are 10:1 over the Dmax forum. A good yardstick of how "good" an engine is, is how dead their forums are. I'm on a few and I can tell you they are pretty dead for the LM2. I've never seen one entry yet of anyone pulling the head off of a LM2....

MRC alone doesn’t give you ride height adjustability - for that you need MRC plus air ride. That combo is optional on the high country, but MRC alone is standard. If you’ve got them both then the height adjustment is done with the lower half of the drive mode knob. This generation doesn’t have load leveling rear unless you have both MRC and air ride.

Not sure about your leveling question - pure guess is the link extenders would keep the ride quality close to stock. Also might be better for the longevity of the shock than the spacer alone? I’m sure some folks here can give better answers.

This is true. I went with the 5.3 after 9 years of ownership and 135K trouble free miles in our 2011 so now hoping that desicion doesn't come back to haunt me
