The Chevrolet Silverado 1500 Speedometer Calibrator by Rough Country is the perfect solution for ensuring your vehicle's speedometer is accurately calibrated, even when you've upgraded to larger tires. Designed for '07-'18 models, this device makes sure you're always in sync with your actual speed.

Delve deeper into the capabilities of this speedometer calibrator, and you'll find a host of features that cater to those who love to modify their trucks. When larger tires are installed on your Silverado, the original speedometer settings may no longer reflect your true speed. This innovative device connects seamlessly to your vehicle’s Diagnostic Link Connector Port, allowing you to accurately reprogram your vehicle’s speedometer within minutes. Furthermore, it integrates with the vehicle's ECM to adjust shift points and electronic stability control, ensuring smooth performance on any terrain. Not only does it correct speed readings, but it also offers diagnostic functions, enabling you to read and manage “check engine light” warnings with ease, and even reset the speedometer back to stock settings when needed.
