Retro 6 Gauge Set | 85mm GPS Speedometer, 8000RPM Tachometer, and 52mm Water Temp Oil Pressure Fuel Meter Voltmeter

This complete 6 gauge set gives you all the essential readings for your car, boat, or diesel vehicle. The kit includes a large 85mm GPS speedometer and tachometer, plus four 52mm gauges for water temperature, oil pressure, fuel level, and voltage. It is a practical upgrade for anyone who wants a clean, retro look with modern GPS speed tracking.

The GPS speedometer works on DC 12V or 24V systems and does not need a mechanical speed sensor. It picks up satellite signals to show your speed on a bright yellow and red backlit display. The 85mm tachometer monitors engine RPM up to 8000 and includes a programmable overspeed buzzer alarm. Both large gauges are waterproof and fit into a standard 85mm panel cutout.

The four 52mm gauges cover your engine's vital signs. The water temperature gauge reads from 40 to 120 degrees Celsius. The oil pressure gauge measures from 0 to 10 Bar. The fuel level gauge works with a 0 to 190 ohm sender. The voltmeter monitors your electrical system from 8 to 16V on a 12V system. All gauges share the same yellow and red backlight color scheme for a uniform dashboard look.

Installation is straightforward with the included wiring diagrams. Each gauge comes with a fastening ring and wiring harness. The package does not include sensors, so you will need to order those separately if required. This set is a smart choice for custom builds, restorations, or replacing old broken gauges.

Key Features and Benefits

- GPS speedometer works on DC 12V or 24V and does not need a mechanical sensor, so installation is simpler

• 85mm large gauge size gives you a clear and easy-to-read display at a glance

• Yellow and red backlight on all gauges creates a consistent retro look across your dashboard

• Programmable overspeed buzzer alarm on both the speedometer and tachometer helps you stay within safe limits

• Waterproof construction on the main gauges adds durability in marine or outdoor vehicle use

• Four 52mm gauges cover water temperature, oil pressure, fuel level, and voltage for complete engine monitoring

Who Is This For

- Car enthusiasts building a custom dashboard or upgrading an older vehicle with modern GPS speed tracking

• Boat owners who need waterproof gauges that work on both 12V and 24V electrical systems

• Diesel vehicle owners who want a complete gauge set for monitoring engine vitals like oil pressure and water temperature

• Anyone replacing a broken or outdated gauge cluster who wants a matching set with a retro aesthetic

Usage Scenario

Mark was restoring a classic 4x4 and wanted to replace the old, inaccurate gauges. He chose this 6 gauge set because the GPS speedometer meant he did not have to run a mechanical cable. After cutting the 85mm and 52mm holes in his custom dash panel, he connected the wires following the color-coded diagram. The yellow backlight matched the warm glow of his other interior lights. Now he can see his speed, RPM, water temp, oil pressure, fuel level, and voltage all in one place. The overspeed buzzer gives him peace of mind when driving on the highway.

Micro Comparison

Many gauge sets require separate sensors for the speedometer, which adds cost and installation complexity. This set uses GPS for the speed reading, so you only need to mount the antenna with a clear view of the sky. The four 52mm gauges cover the same functions as individual aftermarket gauges, but they come as a matching set with the same backlight color. This saves you time matching different brands and ensures a uniform look on your dashboard.
