So I would love to know the top speed you have hit with your truck and what performance if any mods it had when you did so. I know the speedo only go's up to 85 but there are other ways of knowing speed (gps and what not). I know that with stock set up, stock size street tires, the renix 4.0, auto, 2wd, with 3:55 gear ratio, I got it up to 112 mph. How ever the other day I got it up to 96 mph thats with newish 31" all terrain tires, 4:10 gear ratio, about 300 lbs in the bed, and some other "minor" problems. So tell your story :popcorn:
