3-3/4in Autogage Tach - 10K RPM w/Shift Light

The 3-3/4in Autogage Tach - 10K RPM w/Shift Light by AUTOMETER is a precision analog tachometer built for serious performance enthusiasts and engine builders who demand accurate real-time RPM monitoring. This compact gauge delivers critical engine speed data at a glance, enabling you to optimize shift points, monitor redline approach, and protect your engine from over-revving during aggressive driving or dyno testing. The integrated shift light function provides visual feedback just before peak performance RPM, making it an essential tool for track drivers, street racers, and weekend warriors pushing high-output powerplants.

AUTOMETER's Autogage line is engineered with reliable stepper-motor movement that delivers smooth, responsive needle sweep across the 10,000 RPM range—critical for detecting rpm fluctuations during tuning adjustments, fuel mapping, or transmission calibration. The 3-3/4-inch diameter fits standard 52mm gauge pods, dash openings, or custom mounting locations without requiring extensive modification. The shift light triggers at a user-adjustable threshold, providing an unmistakable visual alert when engine speed approaches your predetermined RPM ceiling, preventing unintended over-speed conditions and extending engine longevity during spirited driving sessions.

This tach is ideal for forced-induction builds, LS swaps, naturally aspirated high-revving engines, and any modified powertrain where factory instrumentation falls short. Installation requires a tachometer signal wire (typically sourced from ignition, coil pack, or ECU output) and 12V power; most custom chassis and engine bay projects accommodate this gauge without complication. Whether you're road racing, autocrossing, or simply monitoring your engine's performance potential during spirited acceleration, the Autogage 10K RPM tach delivers the accuracy and responsiveness professional tuners and dedicated builders trust.
