    Description

    Advanced Recalibration Tool. Installing larger aftermarket tires causes inaccuracies in your truck’s speedometer readout. That’s what this Rough Country Speedometer Recalibration Tool has been designed to correct. It reprograms your vehicle’s onboard ECM to match the output of your newly installed larger tires so you can accurately determine your vehicle’s performance.

    Accurate Reading. The program installed on this Speedometer Recalibration Tool effectively corrects the discrepancy between your actual speed and the readout on your speedometer based on the size of the aftermarket tire installed on your vehicle. This device has also been engineered to update your truck’s onboard computer to ensure correct shift points and accurate electronic control.

    PC-Compatible. The installation of this Speedometer Recalibration Tool requires an updated version of the Inline Speedometer Corrector Programmer. As such, this tool is compatible with most PCs and may be upgraded by connecting to a Windows-enabled computer.

    Simple to Install. The plug-and-play design of this Speedometer Recalibration Tool lets you install it on your truck quickly and easily. It directly connects to your truck’s Diagnostic Link Connector Port without special modifications or complex rewiring required.

    Backed by a 1-Year Limited Warranty. Rough Country backs this Speedometer Recalibration Tool with a 1-year warranty against manufacturing defects from the date of sale. Some conditions may apply. For more information, please refer to the manufacturer’s website.

    Application. The Rough Country Speedometer Recalibration Tool is designed for use on all 2020-2024 GMC Sierra 2500 HD trucks.
