3-3/8in In-Dash Tach

The 3-3/8in In-Dash Tach from AUTOMETER delivers precise engine RPM monitoring for street machines, race cars, and high-performance builds where real-time engine data matters. This compact in-dash tachometer is purpose-built for drivers and tuners who demand accurate rev readings to optimize shift points, monitor engine health, and prevent over-revving during aggressive acceleration or track use. Whether you're dialing in a carbureted engine, managing a turbocharged setup, or fine-tuning fuel injection parameters, this gauge provides the visual feedback needed to keep your engine operating within safe limits.

AUTOMETER's 3-3/8-inch tachometer uses proven analog needle technology to display engine speed with fast response time and zero electronic lag—critical when you're pushing RPMs hard on the dyno or at the strip. The compact 6.6 x 4.7 x 7.3-inch form factor fits tight under-dash installations without consuming excessive dashboard real estate, while the precision movement and internally dampened needle eliminate flutter and vibration noise common in performance environments. The gauge reads in thousands of RPM, making it easy to spot power band peaks and monitor for dangerous over-rev conditions at a glance, and the lighting design ensures visibility in both daylight and night driving.

Mechanics and engine builders install this 3-3/8in In-Dash Tach in custom street rods, muscle cars, and motorsports vehicles where OEM gauges lack accuracy or don't exist. The lightweight 0.8 lb construction simplifies mounting in compact engine bays, and the standard 2-1/16-inch case diameter accommodates most common gauge pod configurations. This tachometer pairs seamlessly with AUTOMETER's other performance instruments to create a complete digital or analog gauge cluster, giving you full visibility into engine parameters during testing, tuning, or competition driving.
