I created a Colorado post for this same issue but follow the Silverado one also since it has been around longer. I have had a few trips to the dealer the passed couple months where they supposedly RF the tires every time but in my latest trip they found the front drivers side tire out of spec and replaced it (i am still on goodyears). To my surprise this helped a lot. I still feel a very slight shake and see a shake in the seat around 80 but its only at 80 where as it was from 75 and up and was very violent. Like mentioned above it is still a stiff ride which i also figure has to do with the Z71 shocks and it being brand new. I swear i feel everything in the road. It has been 2 weeks so far so I am still monitoring it but it is much better for now and not shaking me up everyday on the freeway. I only know what i have read on here in regards smooth road shake compensation so can't comment much on that but as mentioned i was shocked when it seems to be a front tire issue on what feels like a rear end shake.

Hello everyone, I posted this in the Colorado section but have been reading this thread and feel like it is probably the better place to post. I have a 2015 Colorado that was built 2 months ago and i have owned it for a month and am having the same shakes and vibrations that everyone else seems to be having with the Silverado. Obviously making me super confident in Chevrolet's build quality. My shakes start around 75 but really become noticeable around 80 and up. The passenger seat shakes like a massage chair. I have taken chevy techs for a ride and they agreed there was a shake but then they keep the truck for a week saying they performed tests and couldn't find a shake and just balance the tires. I have since recorded multiple videos with my GoPro attached to the seat that will be hitting Youtube and EVERY other social media if they still try and play it off as No shake or Normal. I read the first 30 pages of the thread and then realized I really don't want to go through all 300+ pages. Has anyone figured out any common fix? I know i have read 1 or 2 people that found something that worked for them such as tires but doesn't seem like its fixed a majority of trucks. I have yet another appointment with my local dealer so I am keeping my fingers crossed they can fix it and i will be showing them this thread Thanks for any help.
