Speedometer Calibrator Gas Chevy/GMC 2500HD/3500HD (17-18)

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.

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!
