Digital Gauges & Monitors

Keep a close eye on critical engine and transmission vitals on your 2006–2007 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LBZ Duramax digital gauges and monitors. When towing heavy loads, running aggressive aftermarket tuning, or pushing your 6.6L LBZ to its limits, the factory dashboard simply does not provide enough information to keep your powertrain safe. Spikes in boost pressure, rising transmission temperatures, and high exhaust gas temperatures (EGTs) can quickly lead to catastrophic failure if left unmonitored. Upgrading to a comprehensive digital gauge display solves this by plugging directly into your truck's OBDII port, giving you instant, real-time access to dozens of crucial parameters without the hassle of plumbing multiple analog gauges or cluttering your A-pillar with bulky pods. These sleek, full-color touchscreen and LCD monitors not only display live data, but also allow you to read and clear diagnostic trouble codes (DTCs), set visual and audible safety alerts, and record peak values. We supply premium digital gauges and expandable OBDII monitoring systems from trusted industry leaders like Edge Products, Banks Power, and Bully Dog. Browse our complete inventory of 6.6L LBZ digital gauges below to protect your investment and monitor your Duramax with absolute precision.
