Speedometer Calibrator | Ford Bronco/Bronco (2 Door)/F-150/F-250/F-350

Rough Country's Speedometer Calibration Device puts the finishing touch on your lifted vehicle, quickly and easily reprogramming your speedometer to match the output of your larger tires.

Why You Need It: Your vehicle's computer tracks speed based on your stock tire height; upgrading to larger tires creates a discrepancy between your actual speed and the speedometer readout.

Performance: Doesn't just change your in-dash readout — updates your vehicle's ECM, ensuring accurate shift points and proper electronic stability control.

Convenient Reset: Includes a function to reset the speedometer back to stock prior to servicing the vehicle.

Warranty: Includes a 1-Year Warranty.
