Gauges are the instruments that show us the things we need to know about our trucks. Is it running hot? How fast am I going? Do I still have oil pressure after bottoming out? These are all questions gauges will answer. Every truck has at least a few gauges, but for the most part those are boring. We compiled this guide to show you what's out there and where to get it. There isn't enough room in this whole book to print every gauge, so we took a sample of the coolest. So sit back and enjoy our guide to gauges.

Auto Meter has a few new lines of gauges for '08: the ES, GS, and Retro. The ES (black bezel) and GS (chrome bezel) gauges are available in short-sweep electric, mechanical, and electric full-sweep. The ES lights up red, while the GS lights up green thanks to Auto Meter's signature, high-definition, through-the-dial LED illumination. The 3-3/4-inch, pedestal-mount, retro-style tachometer accurately reproduces styling cues of the first tachometers produced by Auto Meter in the late '50s and early '60s. Beneath their shiny exterior these tachometers are all business, featuring the same high-quality, race-proven, precision air-core movements that Auto Meter uses in all of its racing tachs.
