3-3/8" Diesel Tachometer | 6K RPM | Classic Design

The Diesel Tachometer delivers clear, real-time RPM monitoring for diesel applications where dependable engine speed data matters. Designed to work with alternator signals (R or W terminal), crank sensor inputs, or magnetic pickup sensors, it integrates cleanly across a wide range of diesel builds and setups. A precision stepper motor keeps the needle smooth and steady, giving you accurate, easy-to-read RPM data without bounce or 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.
