Upgrade Your Speedometer

We know that electronic speedometers get thrown off and need to be recalibrated when you put new wheels and tires on your truck. To tackle that hassle of recalibrating, Summit Racing has come out with a GPS Speedometer Sending Unit. It uses a GPS receiver that links up to a satellite and communicates with your speedometer to tell you how fast you're going. Speeds are related in real-time and are equally as accurate as any mechanical cable-based system.

The unit doesn't require any additional sensors at the transmission or rear-end to work. It works with virtually every OEM and aftermarket electronic speedometer ever made, as well as with most programmable speedometers. A built-in LED indicator lets you know that the GPS unit is operating. For more information, call 800-230-3030 or click here.
