The Ram 1500 Speedometer Calibrator by Rough Country is an essential tool for any truck owner looking to perfectly calibrate their speedometer when upgrading to larger tires. Designed specifically for the 2011-2017 Ram 1500 models, this easy-to-use device ensures your speedometer displays accurate readings in line with your vehicle’s new tire dimensions.

When you install larger tires on your Ram 1500, your vehicle's original speedometer settings will no longer provide accurate speed readings due to the change in tire diameter. Rough Country’s Speedometer Calibrator addresses this issue effortlessly. This plug-and-play device connects directly to your vehicle’s Diagnostic Link Connector Port. Within minutes, it recalibrates the speedometer, adjusts your vehicle’s ECM for precise shift points, and recalibrates the electronic stability control for optimal performance with larger tires. Additional features include the ability to read diagnostic codes for "check engine light" warnings and easily reset your speedometer to factory settings.
