Keep your calibrations in check with the Rudy's In-Line Speedometer Calibrator. Monster mudders, custom rims and aftermarket gear swaps are great for your rig's performance and style, but the vehicle's brain still thinks you're rolling stock. And, that means your odometer and speedometer calibrations are way off.

This module is perfect for vehicles with computers that don’t allow for tire size and/or rear gear ratio correction or re-calibrate for tire sizes and/or rear gear ratios outside the range of programmers.

Using the included USB cable, connect the In-line Speedometer Calibrator Module to your PC and enter the new tire height and/or rear gear ratio. There are no limitations for increasing tire height or rear gear ratios. Next, disconnect the factory connector to the instrument cluster (behind the dash), snap in the Speedometer Calibrator Module, reconnect the cluster, and you’re done! In a matter of minutes, you can accurately correct your speedometer and odometer readings (as required by law).

No more false mileage added to your odometer which affects resale value. And, no more blasting the speed limit—by accident of course—which leads to expensive speeding tickets.



  • Keeps your odometer on track and speedometer in check
  • Allows speedometer and odometer recalibration for tire size and gear swaps
  • Automatically keeps speedometer and odometer calibrated as required by law
  • Your In-Line Speedometer Calibrator is backed by a Lifetime Warranty
