You've made your vehicle fast with Mopar® parts, now it's time to protect your investment with a complement of instruments you can trust to keep you informed of what's really going on under the hood. Officially licensed Mopar® Classic Gauges from AutoMeter are backed by accurate and reliable, track-tested, race-proven Electric performance movements finished in chrome bezels and easy to read black dials emblazoned with the red, white, and blue Mopar® heritage logo. Speeding tickets are no fun. Calibrating a factory speedometer after updating your differential gearing and wheel and tire combo isn't a great deal of fun either. AutoMeter's Electrictronic Programmable Speedometer makes short work of both, providing an easy to install and easy to calibrate solution that will help keep your speed exactly where it needs to be. Compatible with most factory speed senders on late model transmissions as well as AutoMeter's own solutions for classic Mopar® transmissions, you'll wonder why you ever struggled with your speedometer before. Calibration is as simple as a two mile drive, or for even easier operation, AutoMeter's GPS Speedometer Sender is a simple plug and play solution for any application.
