Guide to Gauges

Nothing brings out custom interior style like a set of racing gauges mounted to your vehicle’s dash, console or A-pillar.

From muscle cars and big trucks to sport compacts and street rods, a set of performance gauges not only keeps engine vitals within eyeshot, they add a dose of racecar style like no other accessory. Whether you plan to add automotive gauges and custom gauge faces for performance, security, or style, here’s a quick overview of what you need to know when gauging your gauge needs:

Automotive Gauges

When you spend your hard-earned dollars on auto performance, it’s important to keep tabs on all the vital readings to prevent meltdown, detonation, and catastrophic failure. Whether you’re towing with the big dogs, pulling Gs at the track, or dropping the hammer on your morning commute, quality gauges are a must. But, which gauges are best for your needs? Check out the AmericanTrucks Guide to Gauges and find out.

Fuel Gauges

Fuel pressure, fuel level, or combustion—if it has to do with monitoring the go-juice, you’ll find it here.

  • Air/Fuel Ratio Gauges: By measuring and displaying the air to fuel mixture, an Air/Fuel Ratio Gauge is helpful when accurate readings are required to maximize power, reliability, and mileage on highly-modified vehicles. Narrow Band sensors only indicate whether or not your vehicle is running at the ideal ratio of 14.7:1. Wide Band sensors display the entire ratio range, which is important for high-performance vehicle tuners.
  • Fuel Level Gauges: One of the easiest gauges to take for granted—until it fails and you run out of fuel. Aftermarket Fuel Level Gauges usually require special, vehicle-specific senders and don’t always work with factory gear. Make sure you get everything you need when ordering.
  • Fuel Pressure Gauges: Sitting between your fuel filter and your carburetor or fuel injection, the Fuel Pressure Gauge basically measures how much fuel is being delivered. Since they work off of actual fuel pressure, never mount one of these gauges in your cockpit unless you use an inline fuel isolator.
  • Knock Gauges: Knock Gauges measure knock or detonation—the engine-killing result of too much boost, over fueling, mistuning, and inadequate cooling.

Pro Tip: Customize Your Gauge Face

For a truly personalized touch, consider customizing your gauge face. Gauge faces can be tailored to match your vehicle's interior design, allowing you to add a unique and stylish element to your dashboard. You can choose from various colors and styles to create a one-of-a-kind look that complements your car's aesthetics.


Adding performance gauges to your vehicle not only enhances its functionality but also brings a distinct racing style to your interior. From monitoring fuel levels to tracking engine performance, the right gauges are essential for any automotive enthusiast. With proper installation and customization options like gauge faces, you can create a personalized and functional dashboard that reflects your unique style and performance needs.
