The Chevy Silverado 2500 HD Speedometer Calibrator by Rough Country is designed for '20-'23 models to ensure your vehicle's speedometer is precisely calibrated. This user-friendly device allows you to adjust your speedometer settings to account for the larger tires on your modified vehicle.

When upgrading to larger tires, your vehicle's speedometer may display inaccurate readings due to the stock tire size settings in your vehicle's computer. The Rough Country Speedometer Calibrator resolves this issue by reprogramming your vehicle’s speedometer to reflect accurate speeds, ensuring the proper functionality of your vehicle's electronic systems. This plug-and-play device connects to your vehicle's Diagnostic Link Connector Port, making it easy to install and operate.
