Hypertech (730129): In-Line Speedometer Calibrator Module for 2019 GM 1500

Perfect for GM 1500 trucks with computers that don’t allow for tire size correction (or that have tire sizes outside the range of programmers), the 730129 In-Line Speedometer Calibrator from Hypertech is the best way to recalibrate your speedometer and odometer for larger-than-stock tires. This product has no limit for increasing tire height, while it has a lower limit of 50% of your 1500’s stock tire size. Hypertech designed the In-Line Speedometer Calibrator for an easy plug-and-play installation into the factory wiring harness—no splicing required!
