The Dakota Digital RTX Series Gauge Cluster for 1957 Chevrolet Cars delivers the ultimate instrumentation upgrade for the crown jewel of the Tri-Five era. Part of Dakota Digital’s Retrotech philosophy, this system is engineered to preserve the iconic, original dash layout while packed with 21st-century precision and late-model drivetrain compatibility.
This drop-in cluster fits perfectly into your original or reproduction cast housing using factory hardware. (Note: The original cast gauge pod housing and decorative chrome inserts/rings are not included; you will reuse your stock ones or source reproductions).
The Visual Illusion: 3 Gauges Off, 6 Readings On
When the ignition is switched off, the cluster presents a flawlessly clean, concours-original 1957 look. The magic happens when you turn the key:
-
Concealed Electronics: While it visually mimics a stock 3-gauge dash layout, three additional high-precision readings (Tachometer, Oil Pressure, and Voltmeter) reveal themselves using clever, hidden LED bar-graphs that remain completely invisible when the car is turned off.
-
The Symmetrical Hub: A large, high-definition full-color TFT digital message center sits front and center, providing a customizable display window for diagnostics, trip metrics, and performance trackers without interrupting the retro face styling.
-
Customizable RGB Backlighting: Features over 30 user-selectable color zones allowing you to independently change the illumination of the sweeps, needles, and digital message areas. You can choose from 12 pre-programmed color themes or design your own, complete with automatic daytime and nighttime brightness level dimming linked directly to your vehicle's factory headlight switch.
Comprehensive 6-Gauge Reading Package
The system transitions your vintage Tri-Five into a complete data hub with a blend of classic sweeps and digital bar-graphs:
-
Analog Speedometer: 0–120 MPH (Optional metric version: 0–240 km/h)
-
Analog Water Temperature: 100–260°F (Optional metric version: 40–120°C)
-
Analog Fuel Level: E, 1/4, 1/2, 3/4, F
-
Digital Bar-Graph Tachometer: 0–8,000 RPM
-
Digital Bar-Graph Oil Pressure: 0–80 psi
-
Digital Bar-Graph Voltmeter: 9–17 VDC
Built-In Safety Indicators & Performance Trackers
-
Hidden Indicators: The face incorporates modern diagnostic warning lamps that stay hidden until active, including Left/Right Turn Signals, High Beam, Check Engine, Parking Brake, and Cruise Control. Each analog gauge sweep also houses a red warning LED that flashes during critical over-limit parameters.
-
Track Metrics: Log your classic's street performance with integrated electronic timers for 0–60 MPH, 1/8-mile, and 1/4-mile runs, alongside trap speed, high-speed, and high-RPM recall.
Consolidated Control Box & Bluetooth Setup
Wiring individual modern gauges behind a tight 1957 dash can quickly turn into a cluttered nightmare. The RTX series solves this by routing all engine bay and speed signals to a single, compact Central Control Box (5.5" x 3.5" x 1") that can be tucked away cleanly.
System calibration—including setting the odometer to match your vehicle's true mileage (a one-time user configuration)—can be handled via the included external hardwired two-sided rocker switch. For an even more intuitive setup, the cluster features built-in Bluetooth compatibility. Simply download the free app to your Apple or Android smartphone or tablet to calibrate your speedometer, adjust warning limits, configure color profiles, or view live diagnostic readouts.
Premium Solid-State Sensors Included
The package comes complete with ground-isolated, modern sending units to get your project up and running:
-
Oil Pressure & Water Temp Sending Units: 1/8" NPT solid-state sensors with a 10-foot wiring harness and a comprehensive installation bushing kit (1/4", 3/8", and 1/2" NPT, plus 12mm and 16mm x 1.5 thread adapters).
-
Electronic Speed Sensor: A modern 3-wire pulse generator that replaces your old mechanical GM speedometer cable. (Requires 5 inches of clearance extending from the transmission cable output; a relocation generator adapter is available separately if body or crossmember clearance is tight).
