1973-87 Chevy/GMC Pickup HDX Instrument System

The 1973-87 Chevy/GMC Pickup HDX Instrument System is a modern digital gauge cluster designed to replace aging analog instrumentation in classic C-series and K-series trucks. Built by Dakota Digital, a leader in customizable digital instrumentation for classic and hot rod vehicles, this system delivers accurate real-time engine data while maintaining the authentic aesthetic of vintage Chevy and GMC pickups. Whether you're restoring a 1973 square-body or updating a mid-80s model, this gauge platform provides the reliability and precision modern drivers expect from their classic trucks.

The HDX system uses high-resolution LED displays and programmable digital readouts to monitor critical engine parameters—fuel level, coolant temperature, oil pressure, voltage, and RPM—with accuracy that far exceeds original mechanical gauges. The modular design allows customization of display layouts and warning thresholds, enabling tuners and mechanics to tailor readings to specific engine modifications or performance builds. The compact physical dimensions (14.6 x 6.9 x 24.35 inches) fit standard instrument cluster openings without requiring extensive dashboard fabrication, and at 7.55 pounds, installation weight is negligible compared to original cast-iron gauge clusters.

This instrument system is ideal for restoration enthusiasts, performance builders, and daily-driver restomod projects where reliability and accurate diagnostics matter. Engine swaps, carburetor conversions, and fuel injection retrofits all benefit from the HDX's ability to read modern sensors and provide real-time feedback. Installation integrates with existing wiring harnesses in 1973-1987 Chevy and GMC pickups, and Dakota Digital's technical support ensures proper configuration for your specific application—whether you're running stock power or a built small-block Chevy.
