Keep An Eye On Your RPMs With Confidence And Clarity

Whether you're upgrading your dash or finishing a custom build, having a clean, reliable tach is one of those details that takes your setup from functional to professional. The Isspro R8585M electronic tachometer is built for drivers who want clear, accurate engine RPM readings without the clutter or overcomplication. Its 3-3/8 inch gauge size fits nicely into a variety of dash layouts, while the analog dial gives you easy visibility at a glance. It reads from 0 to 4000 RPM, making it ideal for diesel builds or lower-revving gasoline applications. You can run it with a variety of signal sources including magnetic senders, alternator taps, or pulse generators, which means it works just as well in a retrofit project as it does in a clean race dash. The display is crisp and easy to read, day or night, and the durable construction holds up to vibration and heat over the long haul. When you want to know exactly what your engine’s doing without second-guessing your signal, this tach delivers every time.

Built For Versatile Signal Input And Reliable RPM Tracking

The Isspro R8585M 0–4000 RPM electronic tachometer is engineered for use in a wide range of applications requiring accurate engine speed monitoring. With its 3-3/8 inch housing, this gauge offers universal compatibility and accepts signal input from magnetic pickups, pulse generators, or alternator taps. It is designed to function on 12-volt DC systems by default and can be adapted for 24-volt systems with the purchase of a 24V-compatible backlight bulb. The electronic circuitry inside the gauge ensures responsive and stable needle movement for precise RPM tracking, especially important in high-vibration or performance environments. This tach is an ideal fit for diesel applications where engine speed needs to be monitored below the 4000 RPM range. Its analog display format offers a traditional look with modern internals for dependability and quick signal response. Whether you're restoring a classic diesel or outfitting a fresh custom build, this gauge offers the flexibility and durability your setup demands.
