I will admit it is very rare...and the utility is also rare but i hit the speed limiter recently making a pass on the highway around left lane hogs slowing down a ton of traffic.  98mph?  Really?  Most highways around me the typical speed is 80mph.  Feel like my 2011 didnt have this limit...but cant recall

 

Anyone know how to remove the limiter?

I believe the previous gen is the same. Thought I had read somewhere that its due to the drive shaft or something not being able to handle the stress of higher speeds. Could be wrong.

Mine kicks in at 112, which incidentally  is the speed rating of my tires.

Hmmmm....how does the computer know what tire rating i have?

Not to tough for them to know what tires it was born with, and of course, that's where the limiter gets set.

The the best of my knowlege it is about the factory equipped tire.

20” wheels with 275/60/20 tend to be 112mph
18” wheels regardless of tire 98mph

The 22” 265/50/22 with Alenza tires also 112

I have the 22” Alenzas, and it shuts down at 107.

I cant say for certain for these trucks, but on the K2's they were limited because of driveshaft overspeed. The limit was different depending on the transmission and final drive ratio. There were numerous modded truck people saying they had their DS explode around 115mph. Which is not something I would want to experience. As stated, tire speed ratings come in to play. Most quality OEM size All Terrain tires are usually in the 98-112mph range.

That sucks, as I was hoping on cruising at 112.

This is something that my guy just learned about with his 2020 GMS Sierra SLT- this was never disclosed anytime or anywhere  during the selling of this truck.  THIS SHOULD BE  FULL DISCLOSURE to the customer.  Way to go GMC! now this a serious issue not knowing!  At least Corporate knows🤫- not the consumer!

      3.59 Kroger’s in Montgomery Tx. 20 cents higher than most around here. Very unusual. Saturday they were 3.49.

      Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks.

      Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL.

      Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
