The Dakota Digital GRFX Series Gauge Cluster for 1955–1956 Chevrolet Cars brings a whole new generation of graphic display technology to the legendary launch of the "Tri-Five" era. Moving past traditional analog limitations, the GRFX series provides an incredibly deep level of screen customization and advanced functionality tailored for high-end restomod builds.
Infinite Display Customization
The standout attribute of the GRFX series is its graphic versatility. Rather than being locked into fixed physical needles, nearly every element can be personalized to fit your exact taste:
-
Selectable Readout Styles: Each individual gauge location can be configured to display as a simulated analog needle, a live digital numeric readout, or a responsive bar graph.
-
Data Grouping: Screen real estate can be configured to show readings singly or grouped in pairs, allowing you to double your visible data points on a single layout.
-
Ambient Adjustments: An internal photosensor automatically adjusts screen contrast and brightness between high-sunlight situations (Auto High Contrast) and night driving (Auto Night Mode).
Cutting-Edge Restomod Integration
Dakota Digital has integrated several premium standalone features directly into this instrument cluster:
-
Reverse Backup Camera Input: A first for the automotive aftermarket, the cluster utilizes its largest internal display screen to show live video footage from a backup camera (cameras sold separately) directly in your main line of sight while backing up.
-
Onboard GPS Speedometer Assist: The system incorporates integrated GPS technology for no-touch automatic speedometer calibration, using the satellite signal as a live reference to correct your speed regardless of rear-gear changes or tire sizing.
-
Integrated G-Meter: A graphical display tracks and records real-time G-forces as you accelerate, brake, or carve through corners.

Simplified Setup & App Connectivity
To prevent a birds-nest of wiring behind your classic 1955 or 1956 dashboard, all engine bay sensors route straight to a single, compact External Control Module (5.5" x 3.5" x 1"). A simple interconnect cable links the module to the cluster.
System menus and more than 30 user-selectable RGB color zones can be navigated via an included hardwired two-sided rocker switch. For effortless tuning, use the built-in Bluetooth connection to link your Apple or Android smartphone or tablet to the free Dakota Digital app. A built-in USB port allows you to upload future firmware updates or newly released factory graphic themes.
Complete Hardware & Premium Warranty
The system arrives with a comprehensive sensor package, including a 1/8" NPT ground-isolated water temperature probe, a solid-state oil pressure transducer, a cable-replacement electronic speedometer pulse generator, and an assortment of NPT and metric adaptation bushings. This entire package is engineered and produced in Sioux Falls, South Dakota, and carries a Limited Lifetime Warranty.
