Ensure accuracy in your vehicle's performance with the Chevrolet 3500HD Speedometer Calibrator by Rough Country for '24-'25 models. This essential tool is designed to precisely recalibrate your speedometer, maintaining accurate readings when upgrading to larger tires on your pick-up truck.

The Rough Country Speedometer Calibrator is your go-to solution for overcoming common discrepancies that arise when you equip your Chevrolet 3500HD with larger tires. Your truck's factory-set computer system is initially configured for stock tire sizes, often resulting in incorrect speed readings after upgrading. This compact yet powerful device efficiently addresses these issues, guaranteeing that your speedometer displays the correct speed without any need for complex tools or extensive set-up.

What sets the Rough Country Speedometer Calibrator apart is its user-friendly, plug-and-play installation process, linking directly to your truck's TCM and BCM. With this calibrator, updating your vehicle’s Electronic Control Module (ECM) for correct shift points and electronic stability control settings when you modify your tire size becomes a breeze. It's not only about correcting your speedometer; it's about enhancing and optimizing your truck's overall performance for safer and smoother riding.
