Best Gauges For Diesel Trucks: Compare Sets and Individual Gauges

#1 · Best Overall

1. GlowShift Tinted Diesel Set

• Material: Nylon
• Material Type: Nylon

Best for: Boost, EGT, and fuel readings.

Why it ranks #1: Covers three useful readings—0–60 PSI boost, 0–1500°F EGT, and 0–30 PSI fuel pressure—in one coordinated gauge set.

This tinted three-gauge set pairs 60 PSI boost and 1500°F EGT readings with a 0–30 PSI fuel-pressure gauge. That combination lets diesel owners monitor turbo pressure, exhaust heat, and fuel pressure together, while seven solid colors and two color-cycle modes provide lighting choices.

Each of the three gauges measures a different system: boost spans 0–60 PSI, exhaust-gas temperature spans 0°–1500°F, and fuel pressure spans 0–30 PSI. Having those readings together can support a broader monitoring layout than a set that substitutes transmission temperature for fuel pressure. The three 2-1/16-inch gauges share the same size, and their seven solid illumination colors plus two cycle modes allow coordinated display settings. Transmission temperature is not part of this listed trio.

Skip it if you want transmission-temperature monitoring in the set; the GlowShift GS-C7-DS1- includes that gauge instead of fuel pressure.

Choose this set if boost, exhaust heat, and fuel pressure are the three readings you want to monitor together. Its fuel-pressure gauge is the deciding distinction for buyers who would rather include transmission temperature.

#2 · Best Transmission Monitoring Set

2. GlowShift Black Diesel Set

• Material: Nylon
• Material Type: Nylon

Best for: Three-metric diesel monitoring.

Why it ranks #2: Combines 0–60 PSI boost and 0–1500°F EGT with transmission temperature readings from 80° to 260°F.

A matched three-gauge set combines 60 PSI boost, 1500°F exhaust-gas temperature, and transmission-temperature readings in one package. It lets diesel-truck owners watch turbo pressure, exhaust heat, and transmission fluid temperature together rather than selecting separate gauges for those three measurements.

Each 2-1/16-inch gauge covers a distinct operating measure: boost from 0 to 60 PSI, EGT from 0° to 1500°F, and transmission temperature from 80° to 260°F. That spread gives drivers a broader monitoring view across engine and transmission conditions. The shared gauge size supports a consistent installation layout, while the black seven-color series offers color choices for the interior. This set is specifically centered on those three readings; fuel pressure is not among its listed gauges.

Skip it if you need fuel-pressure monitoring in the same set; the GlowShift GS-T7-DS2-SM includes a 0–30 PSI fuel-pressure gauge.

Choose this set if you want boost, exhaust temperature, and transmission-fluid temperature visible together in a coordinated 2-1/16-inch layout. Its listed trio does not include fuel pressure, so buyers prioritizing that measurement should choose a different gauge combination.

#10

10. GlowShift Black 35 PSI Boost Gauge

• Material: Nylon
• Material Type: Nylon

Best for: Lower-range boost monitoring.

Why it ranks #10: Measures boost from 0 to 35 PSI, a narrower range than the 0–60 PSI alternatives, while retaining seven solid color modes.

A 0–35 PSI scale makes this GlowShift gauge a focused option for diesel owners whose boost-monitoring needs fit that range. Its 2-1/16-inch face combines a clear lens and illuminated red needle with seven solid colors and two color-cycle modes for a customizable dashboard display.

The black dial and clear lens keep the gauge’s analog presentation straightforward, while the seven solid illumination colors and two cycle modes give drivers several ways to coordinate its lighting with the vehicle interior. At 2-1/16 inches, its face matches a common gauge size used in the listed GlowShift sets. The 0–35 PSI range is the key selection boundary: it offers a dedicated boost reading, but buyers needing a scale that reaches 60 PSI should select a different model.

Skip it if you need a boost scale extending to 60 PSI; the GlowShift GS-C701_60 covers that range.

This is a sensible match for owners who want a dedicated analog boost display and whose monitoring needs fit its 0–35 PSI scale. Check that range against your intended use before choosing this lower-range gauge.
