Get Accurate Readings without the Fuss with a Summit Racing™ GPS Speedometer Sending Unit

Thanks to the advancement of electronic speedometers, builders can easily install them in a project car while kissing goodbye the job of routing a speedometer cable from the transmission or rear-end to the dashboard. 

The credit goes to GPS sending units like this Summit Racing™ GPS Speedometer Sending Unit. These little micro-processor controlled beauties don’t require any additional sensors at the transmission or rear-end to work. Instead, they use a GPS receiver to link up with a satellite that communicates with your speedometer how fast your car is traveling. Speeds are related in real-time and are just as accurate as any mechanical cable-based system. Possibly best of all, the GPS-based speed readings eliminate the age-old issue of speedometer inaccuracies due to changes in tire height and/or gear ratios.

The Summit Racing GPS Sending Unit accepts industry standard inputs of 4,000, 8,000, and 16,000 pulses-per- mile signal. That means it works with nearly every factory and aftermarket electronic speedometer ever made, and with most programmable speedometers too. A built-in LED status indicator lets you know that the GPS unit is operating.
