Question about this product?
We're happy to help.
Rough Country's Speedometer Calibration Device helps you quickly reprogram your vehicle's speedometer to match the output of your larger tires.
Your vehicle's computer tracks speed based on stock tire height; upgrading to larger tires creates a discrepancy between actual speed and the speedometer readout.
Plug and Play: Connects directly to your vehicle's Diagnostic Link Connector Port; in a few hours your speedometer reads true again. It updates your vehicle's ECM, ensuring accurate shift points and proper electronic stability control.
Reversible: Includes a function to reset the speedometer back to stock prior to servicing the vehicle.
Warranty: Includes a 1-Year Warranty.
