3-3/8in DG/B In-Dash Tachometer

The 3-3/8in DG/B In-Dash Tachometer is an essential instrument cluster upgrade for serious automotive enthusiasts and mechanics who demand real-time engine RPM monitoring. This analog tachometer is purpose-built for drivers who need accurate rev-range feedback during performance tuning, engine diagnostics, or high-RPM driving situations where factory gauges fall short. Whether you're building a custom engine, troubleshooting carburetor timing, or optimizing shift points for a modified powerplant, this in-dash unit delivers the precision instrumentation professional garages and hot-rod shops rely on.

The 3-3/8-inch face provides excellent visibility from the driver's seat while maintaining a compact footprint suitable for custom dashboard installations or retrofit applications. AutoMeter's proven analog design uses a mechanical needle response that reacts instantly to engine load changes—critical when tuning fuel mixture, ignition advance, or supercharger boost profiles where split-second RPM data matters. The DG/B designation indicates compatibility with both traditional distributor-based ignition systems and modern solid-state ignitions, making this tachometer versatile across classic restorations and contemporary engine swaps alike. Its robust construction and sealed gauge face resist vibration, heat, and oil vapor common in high-performance engine bays.

This gauge is ideal for drag racers, street-rod builders, and serious DIY mechanics who require dependable RPM reference without relying on OEM electronics that may not match aftermarket engine configurations. Installation fits standard 3-3/8-inch gauge pod openings found in most custom gauge clusters and dash panel kits. The compact 6.7 x 5.15 x 7.4-inch dimensions allow flexible mounting options in tight engine compartments or dashboard environments. Professional installers and weekend wrenches alike value this instrument for engine diagnostics, performance baseline verification, and ensuring your modified motor operates safely within intended RPM parameters.
