BOSCH Style Line 2″ Triple Gauge Kit – Black Dial
This 2″ triple gauge kit includes Oil/Water Temperature, a Volt meter, and Mechanical Oil Pressure gauges. The kit uses a black dial face with a black bezel for a stealthy, traditional look that complements chrome or dark interiors. Includes 72″ high-temperature tubing with 1/8″ and 1/4″ NPT fittings for flexible routing. Best for classic dashboards with a sober, easy-to-read display. Choose this if you want a cohesive black-on-black appearance.
Best for: Classic builds with dark interiors, chrome accents, or understated instrument clusters. Limitations: Mechanical oil pressure means no electronic sender, which may affect wiring simplicity in some installs.
BOSCH Style Line 2″ Triple Gauge Kit – White Dial
This white-dial, chrome-bezel kit provides the same bundle as the black version, with a brighter dial that improves readability in sunny or high-glare environments. It includes Oil/Water Temperature, Electrical Voltmeter, and Mechanical Oil Pressure gauges, plus 72″ tubing and fittings. Best for light-colored interiors or when you want a classic white-on-chrome contrast. A good upgrade for visibility and a touch of vintage flair.
Best for: Interiors that benefit from brighter dials or chrome accents. Caution: White dials can show dirt or discoloration more readily in dusty garages or sun-bleached dashboards.
MOTOR METER RACING 85mm Pro Series Gauge Set
This Pro Series kit uses 85mm (3-3/8″) gauges for speedometer and tachometer and 52mm (2-1/16″) for fuel level, temperature, oil pressure, and volt. It’s designed for 12-volt systems and supports both gas and diesel engines. Best for performance-focused builds that require larger, more legible dials and a complete set for racing-inspired dashboards. Caution: The 85mm speedometer might require more dashboard space than smaller 2″ kits.
Best for: Performance-minded classics needing bold, easily readable gauges. Better for: Cars with space for larger instruments and a 12V negative-ground system.
JDMSPEED 2″ 52mm Triple Gauge Set
This 3-gauge cluster includes Oil Pressure, Water Temperature, and Volt Meter in a compact 2″ form factor. It’s a budget-friendly option with a black console-style presentation that can blend in with many interiors. Best for: Light-weight projects or first-time gauge installers who want a simple, universal fit for 12V cars. Limitation: Fewer gauges means less comprehensive engine monitoring at a glance.
Best for: Budget-conscious builds that still require reliable monitoring. Choose this if you want a straightforward install without additional sensors or wiring complexity.
RACETECH 110mm 2-in-1 + 4-in-1 Gauge Set
This 110mm instrument combines speedometer and tachometer as a 2-in-1 unit, plus a separate 4-in-1 gauge block for oil pressure, water temperature, fuel level, and volt. It features GPS-based speed reading, a robust stainless-steel bezel, and IP-67 protection. Best for: Modernizing a classic ride with GPS accuracy and a full set of essential gauges in one cluster. Limitation: Higher price and larger footprint may not suit tight dashboards.
Best for: Enthusiasts who want GPS-based speed readouts plus comprehensive engine monitoring in a unified setup. Better for: cars with space for a larger instrument cluster and an interest in anti-fog, rustproof construction.
Buying Guide
What should I consider when choosing gauge kits?
Gauge size matters for readability and fit. Smaller 2″ units work well in tight dashboards, while 3- or 4-inch sizes create a bolder look and easier reading at a glance. Consider the number of gauges you need and whether you want a single, cohesive color scheme (black or white dials) or a contrasting dial for visibility.
Do I want a mechanical or electrical gauge setup?
Mechanical oil pressure gauges use tubing and mechanical movement, while electrical gauges rely on sensors and wiring. Mechanical options can simplify wiring but may require more tubing, whereas electrical gauges offer easier integration with modern wiring but depend on sensor compatibility and power sources.
Is GPS speed measurement important for my classic?
GPS-based speedometers provide accurate readings independent of vehicle speed sensors. They are ideal for show cars or restorations where original speed sensor compatibility is uncertain. They require a GPS module and may need additional installation space.
What about installation and compatibility?
Verify 12V negative-ground compatibility, sensor fittings (1/8″ or 1/4″ NPT), and whether your dash can accommodate the kit’s dimensions. Some sets include extensive wiring, hoses, and adapters; others are more plug-and-play. Consider the routing space behind the dash and the ease of mounting bezels.
How durable should gauges be?
Look for gauges with durable casings, clear lenses, and anti-fog or UV-resistant properties for longevity in varied climates. Stainless or chrome bezels add a classic look, while black bezels blend with darker interiors.
FAQ
- What gauges are essential for a basic upgrade?
- Are 2″ gauges sufficient for a classic dashboard?
- Does dial color affect readability?
- Should I choose a kit with included tubing and fittings?
- Can these gauges work with older wiring?
- Is GPS speedometry necessary for a classic car?
A basic upgrade typically includes Oil Pressure, Water Temperature, and Volts. If you want engine health at a glance, add a Tachometer or Speedometer depending on your needs.
2″ gauges fit many dashboards and provide clear readability. For more data at a glance, consider 3″ or 4″ gauges or a combined 2-in-1/4-in-1 set like the RACETECH option.
Yes. White dials on black bezels offer high contrast and are easy to read in bright light. Black dials on dark bezels can blend into the dash but suit darker interiors.
Yes. Kits that include tubing and fittings simplify installation and reduce the need to source separate parts. Check that the fittings match your engine sensor ports.
Many kits are designed for standard 12V negative-ground systems and can be adapted to older wiring. Verify the wiring requirements and the presence of any needed sensors or adapters for your vehicle.
GPS speedometry is optional but beneficial for precise speed readings when the vehicle lacks reliable speed sensors or when restoration accuracy matters for display purposes.
