Features

Put the finishing touch on your lifted vehicle with Rough Country’s Speedometer Calibration Device! This easy-to-use Speedometer Calibrator helps you quickly and easily reprogram your vehicle’s speedometer to match the output of your larger tires.

Your vehicle's computer is designed to track the speed based on your stock tire height. When upgrading to larger tires, there will be a discrepancy between your actual speed and the readout on your speedometer.

This plug and play device connects directly to your vehicle’s Diagnostic Link Connector Port and in just a few short minutes your speedometer reads true again! Rough Country’s Speedometer Calibration Devices don’t just simply change your in-dash readout, they update your vehicle’s ECM, ensuring accurate shift points and proper electronic stability control.

Finally, you can get an affordable and accurate speedometer calibration with an easy and intuitive setup process! This device can also easily read and check all diagnostic codes to help you manage “check engine light” and “service needed” messages, and also includes a function to reset the speedometer back to stock prior to servicing the vehicle. Includes a 1-Year Warranty.

  • Resets your speedometer to accurate readings for larger tires.
  • Easy Plug and Play connection.
  • Updates OE ECM Shift Points to accommodate larger tires.
  • Recalibrates Electronic Stability Control to work with larger tires.
  • Reads diagnostic codes like "check engine light".
  • Option to return to stock settings.
  • 1-year warranty.

          Not bad

          Got to recalibrate my speedometer after adding bigger tires. Much closer to true speed than before but still not perfect

            The rough draft

            Operation Reconnect
            Operation Reconnect
            Jul 1

            Operation Reconnect is a unique organization that provides the "gift of time" to soldiers and their families who have faced the challenges of overseas combat deployments. The non-profit group, founded and operated by former and current service members, provides an opportunity for post-9/11 combat veterans to enjoy quality family time in Alabama and Florida. It takes over 125 volunteers and a huge community effort to raise the money needed for the success of Operation Reconnect.
