Speedometer calibrators are a must have for anyone who has changed their tire size or differential gear ratio. A speedometer calibrator updates your truck's ECM to take into account the different size of tires and/or differential, and makes sure your speedometer and odometer are reading correctly. Save yourself some unnecessary speeding tickets, and inflated miles, and get a speedometer calibrator from RealTruck.com.
