Rough Country’s Speedometer Calibration Devices not only change your in-dash readout, but they also update your vehicle’s ECM, ensuring accurate shift points and proper electronic stability control.

This device includes a function to reset the speedometer back to stock prior to servicing the vehicle.
It includes a 1-Year Warranty.
