If you’re looking to breathe some fresh life into your 1970-74 Challenger or 'Cuda Rallye dash, you’ve hit the jackpot with this bolt-in upgrade. Whether you’re rocking a late model 6.4L or the beastly 426 elephant, this setup has got your back. You’ve got six analog instruments and a clock, all complemented by two full-color TFT message centers that keep you in the loop while you’re behind the wheel.

Using your stock front bezel? Perfect! You can still enjoy LED-lit turn signals and brake indicators. And you get to pick between black or silver face styling to match your vibe. It’s all about personal touch, right?

The HDX system is where the fun really begins. Choose your gauge-face styling—black or silver—and then go wild with the illumination options. You can set independent colors for the gauge readings, needles, and message centers. Calibration? Easy-peasy with the built-in capacitive-touch buttons or the Bluetooth app available for both Apple and Android. Each needle hub is crafted from black nickel plated spun-aluminum, which adds a nice touch of class that matches the buttons.

Now, let’s talk features. You’ve got dead-faced indicators for everything from turn signals to check engine lights, plus a couple of user-definable indicators for whatever you need. And don’t forget the settable warning light for each gauge. Installation is a breeze thanks to the central control box that connects to your vehicle’s harness signals and solid-state sending units.

• Speedometer: 0-160 MPH (there’s an optional metric version that goes up to 240 km/h). The split scale gives you a detailed view, so you can keep an eye on your speed without any guesswork.
• Tachometer: 0-8,000 RPM—perfect for those high-revving moments.
• Oil Pressure: 0-80 psi, keeping you informed about your engine’s health.
• Water Temperature: 100-260°F (or 40-120°C if you prefer metric).
• Fuel Level: E, 1/4, 1/2, 3/4, F—no more guessing on fuel.
• Voltmeter: 9-17 VDC, so you know your electrical system is in check.
• Clock: 12-hour analog clock movement—classic and functional.

And that’s just the basics! You’ve got odometer settings, dual trip meters, and even performance meters that track your 0-60 times and quarter-mile runs. Want to know how fast you went? It’s all there.

When it comes to indicators, you’re covered. Turn signals, high beam, check engine, parking brake, cruise control, you name it. Plus, there are two auxiliary input indicators that you can label however you want. Each analog gauge even has a red LED indicator for quick warnings—except for the speedometer.

Want to customize your look? You’ve got over 30 color options to play with for the needle, sweep, and digital TFT display. Brightness? You can adjust that too, both day and night, straight from the HDX setup menu. If you want even more control, pick up the DIM-1 accessory for on-the-fly adjustments.

With 12 factory preset color themes, you can quickly set up a stunning display, or go all out and customize every color zone yourself. The full LED backlighting not only looks sharp but also ensures you can read your gauges easily, day or night. Whether you’re aiming for that original equipment look or something that really stands out, the HDX Series gives you the freedom to choose.

Fitments: This setup is specifically designed for the Dodge Challenger Rallye from 1970-1974, so you know it’s going to fit like a glove.
