hmmm something aint stirring the kool aid...
By my calculations, with a 3.91 rear gear, to turn 2k rpm at 60 mph with a even a 225 45 18, you'd still need almost a .6 overdrive 5th. And that just doesnt exist.
Figure speedo error, how fast is the truck going versus how fast does it SAY you are going and shoot me an answer back. Also give me your tire size so I can do exact calcs. I was just assuming a big 18 tire, you prbably have a really low profile one like a 215 35, but I didnt want to assume.
