Between the square body style and the way this truck performs, there’s a reason why it’s earned its place as a classic. Do everything you can so that yours is around for years to come, and we’re here to help you make that happen. At GlowShift our focus is creating performance gauges and pods that help you maximize your 6.2L or 6.5L diesel engine. Our lineup of gauges monitor a wide range of engine readings to ensure that your Sierra is running at optimal levels.

35 PSI Boost Gauge Fits 6.2/6.5 Turbo Diesel

Black 7 Color 35 PSI Boost Gauge

GlowShift 35 PSI Boost Gauges are a great fit for any 88-94 Sierra that has a 6.5L or a 6.2L with aftermarket turbo added. You’ll have the ability to easily monitor your GMC’s turbo boost levels from 0 to 35 PSI through one gauge. Installing this gauge will help make sure your turbo is producing the right amount of boost, so you can avoid higher boost pressure levels which could potentially result in significant damage to your diesel engine. 88-94 Sierra stock levels run at about 7-12 PSI, but with a tuned diesel engine those boost pressure levels can go much higher.

1500 EGT Gauge Compatible With GMC Sierra

Black 7 Color 1500° F Pyrometer EGT Gauge

The 1500° F Pyrometer EGT Gauge is essential for anyone driving a 1988-1994 GMC Sierra Full Size Truck 2500HD/3500HD who is pushing for maximum output out of their 6.2L or 6.5L diesel. This Sierra EGT gauge displays readings from 0 to 1500° Fahrenheit to help you ensure that your exhaust gas temperature is not running too hot which could result in engine damage. The install process for the included EGT Probe involves drilling and tapping the exhaust manifold to 1/8-27 NPT and then threading and tightening the included EGT Probe.

Trans Temp Gauge Installs To Detroit Diesel

Black 7 Color Transmission Temperature Gauge

A GMC Sierra Trans Temp Gauge goes hand-in-hand with monitoring 88-94 Sierra 4L80-E transmissions, especially when these trucks are towing heavy loads. This gauge allows you to closely monitor the temperature of your transmission, ensuring that it does not overheat causing significant damage. Once you connect the included electronic transmission temperature sensor with 1/8-27 NPT male threads, this Duramax trans temp gauge will deliver accurate readings from 80° to 260° Fahrenheit.

Fuel Pressure Gauge For GMC Sierra 6.2/6.5 Diesel

Black 7 Color 30 PSI Fuel Pressure Gauge

The 30 PSI Fuel Pressure Gauge displays readings from 0 to 30 PSI. It’s the right gauge for any Sierra Full Size Truck since they run on lower fuel pressure, with an average stock PSI range of 3 to 7 PSI. This GMC Sierra fuel pressure gauge ensures your fuel pressure is running at peak levels, and that it is not too low which could result in damage to your fuel pump or injectors. A Duramax fuel pressure gauge is vital to any 88-94 Sierra 6.2L or 6.5L engine by helping drivers maintain their diesel’s performance through consistent monitoring of pressure levels while driving.
