Upgrade your Chevy Silverado 2500/3500 HD with precision and confidence using the Rough Country Speedometer Calibration Device.

Designed specifically for vehicles outfitted with larger tires, this sophisticated tool offers an easy solution for correcting speedometer inaccuracies that result from tire upgrades. Ensuring your speedometer reflects true speed, this device is a must-have for any truck enthusiast who values performance and accuracy.

Modern vehicles are meticulously calibrated for their original equipment tires, but when you decide to upgrade to larger tires, that precision is compromised. The Rough Country Speedometer Calibration Device directly addresses this challenge. It quickly adjusts your vehicle’s speedometer, aligning it perfectly with the actual tire size, so you can drive with the assurance that your speedometer readings are spot-on.

Thanks to its plug-and-play design, you can connect it directly to your vehicle’s Transmission Control Module (TCM) and Body Control Module (BCM). Within a few hours, and with no need for additional tools or complex setup, your speedometer will be perfectly recalibrated. But the benefits extend beyond accurate speed readings. By updating your vehicle’s Engine Control Module (ECM), this device optimizes shift points and recalibrates your electronic stability control (ESC), ensuring smooth, safe, and optimal performance with larger tires.

Features

• Accurately resets the speedometer for precise readings with larger tires.
• Effortless plug-and-play installation with no additional modifications required.
• Optimizes original equipment ECM shift points for improved performance.
• Recalibrates ESC settings to maintain safety and control with larger tires.
• Conveniently revert to stock settings whenever needed.
• Backed with a comprehensive 1-year warranty.

Designed solely for models equipped with a 10-speed transmission, this device provides the flexibility of easily returning to factory settings. Before servicing or selling your vehicle, simply restore the original settings with this user-friendly feature. Be mindful that the Rough Country Speedometer Calibrator is intended for single-vehicle use at a time. Emissions certification restrictions apply, making it unsuitable for sale or use in California.
