LMM Duramax Digital Gauges

Take complete control of your engine vitals, monitor your emissions system, and track real-time performance on your 2007.5–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD with our selection of LMM Duramax digital gauge kits. Unlike traditional mechanical gauges that require extensive wiring and clutter your interior, modern digital gauge kits plug directly into your OBDII port to instantly pull live data straight from your ECM. With a complete kit, you can simultaneously display critical parameters such as exhaust gas temperatures (EGTs), boost pressure, transmission fluid temperature, and DPF soot accumulation on a single customizable screen. Many of these comprehensive kits also include expandable accessory systems—such as the Edge EAS or FASS Connect system—allowing you to add external pressure or temperature sensors that your factory computer doesn't natively monitor. Whether you need a simple plug-and-play monitor to clear diagnostic trouble codes or a highly advanced data-logging setup with add-on pyrometer probes for heavy towing, we have the complete package for your build. We supply industry-leading digital gauge kits and monitoring systems from trusted brands like Edge Products, Banks Power, aFe Power, and FASS.
