Factory Match Pyrometer Kit for GM Duramax

If you're running your Duramax hard—whether it's towing up a grade, hauling a heavy load, or squeezing every bit of power out of a tune—keeping tabs on exhaust gas temperatures isn't just helpful, it's critical. The AutoMeter Factory Match Pyrometer Kit gives you a precise window into what's happening inside your engine, so you can drive with confidence and avoid costly damage. This 2-1/16" gauge is specifically designed to blend into the factory dash of your 2001–2007 Silverado or Sierra 2500HD/3500HD, matching the OEM look with LED through-the-dial lighting that’s easy to read in any condition. Behind the clean face is AutoMeter’s digital stepper motor movement, which delivers fast, smooth, and highly accurate readings from 0 to 2000F. It’s powered by a high-quality Type K thermocouple, known for its quick response and ability to hold up under extreme heat.

Simple Install

Installation is made simple with the included wiring harness, thermocouple mounting kit, and detailed instructions. You don’t need to be an expert to get this gauge up and running—it’s designed with the DIYer in mind, but durable enough for professional-level applications. It even self-calibrates at startup, giving you added confidence that what you're seeing is spot-on.
