Designed for ease of use, this device quickly and effortlessly recalibrates your vehicle’s speedometer to ensure accurate readings when using larger tires. Resolve Speedometer Discrepancies with Ease: Your vehicle’s computer is calibrated for stock tire sizes, meaning when you upgrade to larger tires, your speedometer will no longer reflect your true speed. With the Speedometer Calibration Device, you can eliminate this issue and restore accuracy. Plug-and-Play Installation: This plug-and-play device connects directly to your vehicle’s TCM and BCM, making it simple to recalibrate your speedometer in just a few hours. No complex setup or tools needed. Optimized for Larger Tires: Rough Country’s Speedometer Calibration Device doesn’t just adjust your speedometer—it updates your vehicle’s ECM to accommodate larger tires. This ensures precise shift points and recalibrates your electronic stability control (ESC) for safe and smooth driving. Easily Return to Stock Settings: Need to revert to factory settings? No problem! This device includes a convenient option to reset your vehicle’s speedometer back to stock prior to servicing or selling.
