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!
Note: Not legal for sale or use in California.
