Found the governor limit this weekend.. ;)

From what I have read, all vehicle's factory speed limits are set for the speed rating of the tires they use on them...Mine was 98 also haha

I was just about to say this. Tires.

Mine's also at 98.

My '16 RCLB with the 5.3L and 3.42 rear end hit 107. I don't know if that was the limit or not, had to slow down, for the corner on a racetrack, of course.

Because full size trucks are not made of the same performance parts that Corvettes are. That driveshaft and LT tires are not designed for it.

 

I agree i dont have proof to back this up but when i had my 11 ram 1500 hemi (2wd) tuned. I forget where i set the gov at but I went past 120 with the revs still climbing. Lucky I didn't blow a tire or hurt something. Its hard to slow a truck down at those speeds

You could have kept on going my 16 ccsb same as yours just z71 hits 112 makes me wonder why did gm give these trucks a high top speed linit on the dash when we cant physically hit it?

My '15 silverado topped out at 98 MPH but my 16 I had going 110 and still was pulling, but I know the limit definitely changed after 2015

It's not just the tires, it's also the drivetrain componants- Some things are just not engineered to go 130 MPH. Transfer cases blowing up, drive shafts snapping, just to name a few..
