The Ford F-350 Super Duty Speedometer Calibrator by Rough Country for models '11-'16 provides an efficient solution for adjusting your vehicle's speedometer when upgrading to larger tires. This inline calibrator ensures your speedometer maintains accurate readings, enhancing your driving experience.

Designed for ease of use, this calibrator offers a straightforward plug and play connection through the vehicle's Diagnostic Link Connector Port. What makes this device indispensable is its ability to update your vehicle's Engine Control Module (ECM), not just the dash readout. By recalibrating the ECM, it ensures accurate shift points and enables the electronic stability control to function correctly with your new, larger tires. If you need to service your vehicle, the calibrator includes the option to revert settings back to stock, adding convenience and flexibility.
