Premium Boost Gauge for HD GM Trucks

If you're running a tuned Duramax or just want to stay ahead of potential issues, keeping an eye on boost pressure is a must—and the AutoMeter Factory Match Boost Gauge makes it easy to do that without sacrificing the look of your interior. Designed specifically to match the factory dash in 2001–2007 GM 2500HD and 3500HD trucks, this 2-1/16" mechanical gauge reads up to 35 PSI, giving you the perfect range for stock or mildly modified setups. Unlike digital or electric gauges, this one uses a time-tested bourdon tube mechanical movement, which means there's no need to wire it into your truck’s electrical system. It runs off a simple 1/8” NPT pressure connection, and AutoMeter includes a full installation kit with nylon tubing, compression fittings, and a 1/4” NPT adapter to make the job painless. Whether you're monitoring boost under heavy load or just want peace of mind during daily driving, the response is quick and reliable every time you roll into the throttle.

High-Quality Construction & Design

The LED through-the-dial backlighting blends seamlessly with your OEM cluster, so it doesn’t look out of place during nighttime drives. And because it’s mechanical, it’s a favorite for drivers who want consistent performance in rugged environments—no electronics to fail, just straightforward boost readings when you need them most.
