Dakota Digital RTX Series Instrument Gauge System for 1955-1959 GMC Trucks.
Update the instrumentation in your 1955-1959 GMC truck with this Dakota Digital RTX Series instrument gauge system. Engineered around the original GMC dashboard, the system uses factory mounting points without requiring modifications to the dash panel. Factory-inspired gauge faces retain the original instrument layout while incorporating electronic needle movements, customizable LED backlighting, and high-definition TFT message centers. Included CNC-machined, chrome-plated aluminum trim rings complete the classic dashboard appearance. The instruments display vehicle speed, engine RPM, oil pressure, water temperature, fuel level, and voltage.
A central control box organizes instrument connections and provides access to the system's electronic functions. The configurable TFT message centers display driving information, including odometer readings, trip distances, a clock, and estimated fuel range. Built-in performance meters track acceleration times, quarter-mile and eighth-mile results, and peak speed and RPM readings. Integrated warning and status indicators provide additional vehicle information, with support for optional gear position monitoring and auxiliary inputs. The RTX system combines the appearance of the original GMC instruments with the monitoring capabilities of modern electronic gauges.
