I don’t know that my description will to terribly helpful since I have an 08 but they felt pretty similar to the stock Auto Ride, which is great, but at the same time, I like the Auto Ride on the 900 and didn’t want to deal with the delete for it to feel similar when I had already replaced all of my shocks with new OEM. I ended up selling them to my father-in-law for his 08 Sierra and we got the matching rear shocks and his truck drives great. The Viking shocks are dual-adjustable for compression and rebound, many adjustable shocks only have one adjustment for both. Atomic Fab also has more options now for spring rates now than when I ordered so you can dial in what you want even more. So, be aware there will be some fiddling to get them setup.
The Bilstein 5100s are great shocks also though. We put those on my uncle’s truck. They will definitely be a softer ride than the Mag Ride.
