QuickCal Speedometer Calibrator

Recalibrate your speedometer instantly and easily with the Rough Country QuickCal Speedometer Calibrator. This amazing device take all the guesswork out of setting your speedometer to give an accurate read-out. In just a couple of minutes you are set and the process can be reversed if needed.

How this works is by using GPS technology to reprogram your vehicle speedometer to match the output of larger tires. The vehicle's computer tracks speed based on a stock tire height. Adding larger tires gives you a false reading. Simply plug the QuickCal Speedometer Calibrator directly into the Diagnostic Link Connector (DLC) port and follow the on-screen prompts. Begin driving the required speed and in a few minutes, the GPS analyzes the difference between the vehicle's speedometer to GPS speed and calibrates your vehicle's computer to output the correct speed.

Simple, affordable and backed by a one year Warranty.
