I had two short wheel base Denalis (a 21 and a 22) and now a 2024 long wheel base AT4. The long wheel base rides SOOOO much better than my Denalis, however some of that has to do with the 20” rims on the AT4 vs. the 22” rims I had on the Denalis.
When it comes to the short wheel base Denali vs what I would believe is identical in the short wheel base AT4, both with air ride and mag ride equipped suspensions the AT4 will ride better with the OEM 20 inch rims mounted. I had an OEM set of AT4 rims I used as a winter setup on my Denalis and it completely transformed the ride. I had tons of what I could describe as cowl shake through the steering column with the 22” OEM rims mounted on my Denalis but that went away with the 20” rims mounted.
