Description
The Dakota Digital GRFX-55C-PU Grafix Series instrument system drops into the OEM front gauge bezel to bring your 1955-59 Chevy Truck into the modern age. Compatible with everything from the original factory engine to the latest LT power, this kit delivers detailed monitoring of your under-hood investment while offering the latest in display technology and customization.
The Grafix Series allows the user to customize nearly every aspect of the instrument system. Choose from a variety of graphic themes, personalize each element with unique display colors and warning modes, and configure each gauge location as Analog, Digital, or Bar-graph. Displays can show readings singly, grouped in pairs, or reconfigured entirely to suit your preference.
This system also integrates a reverse backup video display directly within the instrument cluster, onboard GPS technology for automatic no-touch speedometer calibration, and built-in Bluetooth connectivity for wireless configuration, calibration, and troubleshooting via the Dakota Digital App. A USB access port allows for field updates and future feature enhancements. An external control module keeps wiring tidy and organized, separate from the gauge cluster itself. Engineered and produced in Sioux Falls, South Dakota, this system carries a Limited Lifetime Warranty.
