My speed limiter is set to somewhere around 200 MPH. I have had my truck well over 100 MPH, more times than I can count. These trucks have no issues handling high speeds. That being said, my truck is in pristine condition. Also I am not doing these speeds in traffic, unless everyone is doing the same thing. Try driving in Houston TX. If your not doing at least 90, you'll get run over. You can drive fast, with out being reckless, as long as your vehicle is in good condition. It amazes me, just how well these trucks do handel speeds up, and over 100 MPH, or at least mine does anyway.
