Speedometer Calibration: When larger wheels and tires are added to a Jeep, the speedometer no longer reads correctly. This tool allows you to easily recalibrate your speedometer for tire and gear changes.
Automatic Transmission Optimization: With a greater rotational force from larger wheels and tire, your Jeep's transmission does not know when to shift. The Rough Country Speedometer Calibrator can also be used to set ideal shift points.
Engine Diagnostics: Whether you have a "check engine light" or a "service needed" message, then Rough Country Speedometer Calibrator can both read and clear your codes.
Electronic Stability Control (ESC): After lifting your Jeep you may have noticed that the ESC light on your dash comes on often. This issue can be eliminated by using the Rough Country Speedometer Calibrator to optimize your stability control.
Vehicle Specific Design: The Rough Country Speedometer Calibrator is meant for use with all JL Wranglers and JT Gladiators. It is compatible with all engine and trim options on both 2 and 4 door models.Installation Notes
