speedometer
« on: August 31, 2006, 11:30:00 PM »
Hi All
  On my '79 1/2-ton 4x4, I have a 4" lift with 33" tires.  A couple of years ago I remember somebody posted the formula to change the speedometer gear.  It had to do with the gear ratio, size of tires, etc.  If anyone can remember it or a website, I'd appreciate it.
