3-3/8" Diesel Shift Light Tachometer | 6K RPM

The Diesel Shift Light Tachometer delivers clear, real-time RPM with built-in shift lights to help you stay on top of engine speed under load. Designed for diesel applications, it works with alternator signals (R or W terminal), crank sensor inputs, or magnetic pickup sensors for clean integration across a wide range of builds. Shift lights provide immediate visual feedback so you can manage RPM without taking your eyes off the road. A precision stepper motor keeps the needle smooth and steady—no bounce, no guesswork. 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.
