4-1/2" Dual GPS Speedometer + Tachometer + TS/HB | 140 km/h / 8K RPM

The Dual GPS Speedometer/Tachometer combines speed and RPM in one compact, space-saving gauge. GPS speed provides real-time, calibration-free readings with no drivetrain connection required—just connect power, mount the antenna, and drive. The tachometer works across a wide range of engines for flexible installation in both classic and modern builds. A precision stepper motor keeps the needle smooth, stable, and accurate at a glance. Built with a durable housing and solid aluminum bezel, it’s made for real driving conditions and long-term use. Made in the USA and backed for life.
