Transform the interior of your classic GM muscle car with the Dakota Digital GRFX Instrument System for 1970-1972 Chevy Chevelle SS, Monte Carlo, El Camino, and 1971 GMC Sprint. Designed specifically for vehicles equipped with the factory six-round gauge opening, this premium digital gauge package delivers cutting-edge technology while preserving the unmistakable appearance of one of the most iconic dashboards of the muscle car era.
Whether you're completing a concours-quality restoration, building a modern Pro Touring machine, or restoring a weekend cruiser, the GRFX Instrument System combines factory-inspired styling with customizable graphics, GPS speedometer calibration, Bluetooth connectivity, and advanced digital instrumentation. The result is a dashboard that looks right at home in your classic while providing the accuracy, reliability, and features expected from today's performance vehicles.
Designed as a direct bolt-in upgrade, the GRFX system installs into a stock or reproduction gauge carrier and OEM-style bezel (both sold separately), making it an excellent upgrade for restorations and custom builds alike.
Designed for Legendary GM Muscle Cars
The 1970-1972 Chevrolet Chevelle SS remains one of the most recognizable American muscle cars ever built. Alongside the Chevrolet Monte Carlo, El Camino, and GMC Sprint, these vehicles defined an era of high-horsepower V8 performance and timeless styling. Whether powered by a small block, big block, LS swap, or modern crate engine, these classics deserve instrumentation capable of keeping up with today's performance standards.
The Dakota Digital GRFX Instrument System was engineered specifically for these vehicles, maintaining the classic six-gauge layout while incorporating the latest digital technology hidden behind an authentic factory-inspired appearance.
Complete Dashboard Customization
The GRFX Series is Dakota Digital's most customizable instrument system ever created. Unlike traditional gauge packages, every display can be configured to match your driving style and personal preferences.
Drivers can choose from multiple factory-installed graphic themes while customizing:
- Gauge display layouts
- Digital or analog-style gauge presentation
- Bar graph displays
- Individual gauge colors
- Background colors
- Warning indicator colors
- Nighttime and daytime brightness
- Display themes
Every gauge location can even be reassigned, allowing you to prioritize the information most important to your vehicle build.
Factory Appearance with Modern Performance
At first glance, the GRFX Instrument System appears remarkably close to the original factory gauge package. Once powered on, however, vibrant high-resolution digital displays, smooth gauge animations, and brilliant LED illumination reveal a level of technology that far exceeds traditional analog gauges.
The result is a dashboard that complements the interior of your classic muscle car while dramatically improving readability, accuracy, and functionality.
Advanced Digital Instrumentation
The Dakota Digital GRFX System continuously monitors critical engine and vehicle functions using modern electronic sensors for improved accuracy over factory mechanical gauges.
Perfect for stock restorations, LS engine swaps, fuel-injected conversions, big block builds, Pro Touring projects, and high-performance street cars, the GRFX system delivers dependable readings whether you're cruising the boulevard or making passes at the drag strip.
Automatic GPS Speedometer Calibration
One of the standout features of the GRFX Instrument System is its integrated GPS-assisted speedometer calibration. Traditional electronic speedometers often require recalibration whenever tire size, rear axle gearing, or transmission components change.
The GRFX system eliminates that hassle by utilizing onboard GPS technology alongside the included Vehicle Speed Sensor (VSS). GPS continuously references actual vehicle speed while automatically maintaining calibration for outstanding accuracy regardless of tire diameter or gear ratio changes.
This intelligent hybrid system provides the convenience of GPS calibration while maintaining a stable, real-time speed signal for smooth and responsive gauge operation.
Bluetooth Smartphone Connectivity
Built-in Bluetooth technology allows wireless communication with the free Dakota Digital mobile app for Apple and Android devices. Configure virtually every feature of your instrument cluster directly from your smartphone or tablet without removing the dashboard.
The mobile app allows users to:
- Customize gauge layouts
- Select graphic themes
- Adjust lighting colors
- Modify warning parameters
- Perform gauge calibration
- View live sensor readings
- Troubleshoot vehicle systems
- Access diagnostic information
This level of wireless control makes installation, setup, and future adjustments faster and more convenient than ever before.
Future-Proof USB Update Capability
The integrated USB service port allows Dakota Digital to provide future software updates, new graphic themes, feature enhancements, and additional functionality as they become available. Rather than replacing the instrument system as technology evolves, owners can simply update the software to enjoy the latest improvements.
Clean Installation with External Control Module
Every Dakota Digital GRFX Instrument System utilizes a separate control module that dramatically simplifies installation. Instead of routing dozens of wires directly into the gauge cluster, all sensor connections terminate at the external control box before communicating with the display.
This design provides:
- Cleaner wiring
- Simplified troubleshooting
- Easier installation
- Reduced dashboard clutter
- Professional finished appearance
Complete Sensor Package Included
Your Dakota Digital GRFX Instrument System includes the components needed for a professional installation, including:
- Water Temperature Sensor with full-length wiring harness
- Solid-State Oil Pressure Transducer
- Speedometer Pulse Generator
- Installation harnesses
- Adapter bushings for multiple engine configurations
- External control module
Each sensor is engineered for exceptional accuracy and long-term reliability, helping ensure dependable operation for years to come.
