Good thought on finding one from a Chevy. I didn’t have that option since my truck is a diesel and the only option was a Denali diesel swap..Not sure if he is able to program the Chevy startup on a GMC dash but based on his earlier response, looke like he is.

Yes, WAMS did program it. I don't remember the part number but WAMS provided it. It shows Intellink on start up vs. My link Chevrolet that forms up on the radio screen. After the boot up you'd never know. I just assumed that's the way it was supposed to work. By the way the speed limit shows up on the lower left .

My new Denali dash I had programmed last fall came with a GMC Intellink splash screen. Its in my 2017 High Country. Not really a big deal..but thats how mine arrived. It was a new cluster.

Looks great!

I just had the same tire in a 305/55/20 put on my 2017. A bit wider and shorter than the 295/60. There is a little road noise but not annoying at all and less noise than the K02's I just took off. Couldn't get the K02's to road force within spec and I had an annoying vibration..Nitto's seemed to have solved that problem and like them so far a couple days in.

I have one on my 2017...Awesome cover! Well worth the money IMO

500 miles of towing this past weekend and the truck has been great..MUCH improved with the G2’s.

I’ve had an annoying vibration for a while. Been into the dealer several times and have been through 4 sets of tires due to them not roadforcing within dealer spec. My last set was BFG KO2 305/55/20’s that vibrated terribly. Dealer couldn’t get them even close to spec. Last Friday they put a set of Nitto Terra Grappler G2’s 305/55/20 and the vibration is mostly gone so fingers crossed it stays smooth. I still notice a very slight vibration that doesn’t seem to show itself until the truck has heated up and been driving for a while but its wayyy better than it was with the original Goodyears, Yokohama Geolandr’s and the KO2’s. The vibration has always felt to me like its coming from the rear though vs the floor board vibration you described.

I added Morimoto LED Hi/low and fogs to my 2017.

Doesn't make sense.

What's vibrating? The seat, steering wheel or both? My 2017 passenger seat vibrates after 70mph on certain roads, seems to come and go as it pleases. Steering wheel is smooth as silk. I have a readylift installed in the front, installed by Chevy dealer. The dealer looked at my truck and thought something in the rear underseat storage box was causing the vibration, I emptied it and it made no difference. I noticed when I picked my truck up at the dealer they had the passenger seat all the way back and that helped but hardly a "fix".

275/65/20 will need no less than a +18 offset to clear. The +1 will not clear a 275/65/20 without some trimming.
