I've observed this behavior on other 8 / 10 speeds in Sport mode.... will need to pay more attention (if and when I ever drive our 2024!) if this happens in normal mode on the GM 10 speed.

The suspension stiffens? @jerry455 I could be wrong but I’m not aware of our vehicles having adaptive suspensions in sport mode. I have an 24’ AT4 XL with air ride suspension and never heard of this.

In my '23 Denali, the suspension lowers in Sport mode (and the steering feels tighter, at least on the highway).
I don't have air but the electronic shocks or magnaride, are supposed stiffen. This is from the owners manual for my 2012 Suburban:
Sport Mode
Use where road conditions or personal preference demand a more controlled response. When you enter this mode you will immediately feel a down shift. In this mode, the vehicle also monitors driving behaviors and automatically enables Performance Shift Features when spirited driving is detected. These features maintain lower transmission gears to increase available engine braking and improve acceleration response. The vehicle will exit these features and return to normal operation after a short period when no spirited driving is detected. The steering will change to provide more precise control. If the vehicle has Magnetic Ride Control, the suspension will change to provide better cornering performance.

Sorry, 2021 Suburban.

This got me curious about my 2024 RST with Magnaride so I checked the manual and did not see the same reference to Sport Mode changing Magnaride"to provide better cornering performance". Either they've changed the Sport Mode setting parameters between 2021 and 2024, or just changed what's printed in the owner's manual.
No big deal IMO, this is my 3rd Tahoe but first with Magnaride, and it all around handles so much better than my previous Tahoes that I'm happy with how it performs all around regardless. I don't know how much of that is attributed to the independent rear (my prior Tahoes were previous gens with solid rear axle) or how much is attributed to this one being my first with Magnaride. I don't expect 5,700lb trucks to necessarily feel sporty, but this 6.2L with Magnaride feels pretty dang sporty for what it is.
