If you hate not knowing precisely where you stand – especially when it comes to mph and distance traveled – there’s no better way to upgrade the way you drive than with the always-accurate Pro Comp Accu Pro Speedometer & Odometer Calibrator.
The ideal calibration tool for vehicles with larger wheel and tire combinations or gear-ratio changes, a compact Pro Comp Odometer Calibrator plugs right into your diagnostic port for easy installation and from there, offers dead-on readings for speed and distance traveled. In addition, it reads and clears any diagnostic trouble codes (DTCs) that set off your check engine, ABS and airbag warning lights.
Pro Comp Speedo Re-calibrators also correct part throttle shifting and calibrate your speedometer and odometer accordingly whenever you alter your tire size or differential gear changes. Legal in California only for racing vehicles and never suitable for use on highways, they come backed by a Lifetime Warranty.
