GMC Sierra Duramax

The 6.6L Duramax 60 PSI Boost Gauge gives you the ability to easily monitor your 07-13 GMC’s boost levels from 0 to 60 PSI and is designed for any Sierra 2500HD or 3500HD running high boost pressure. This GMC Sierra boost gauge ensures your turbo is performing at optimum levels and that it does not overboost causing critical engine damage. A Duramax boost gauge is a great fit for monitoring pressure levels in your LBZ, LMM or LML when you’re getting more boost out of your stock or upgraded turbo. This gauge is optimal for newer or modified GMC trucks running boost levels in the area of about 30 PSI to 45 PSI.

GlowShift Boost T-Fitting Adapters allow you to avoid drilling and tapping your intake manifold by cutting the MAP line and inserting the T-fitting in the two cut ends. The included hose clamps allow you to tighten the two ends of a MAP line to the T-fitting for an airtight seal which results in extremely accurate boost pressure readings. The T-fitting has a 1/8-27 NPT Female thread for a sensor or compression fittings.

A GMC Sierra Trans Temp Gauge is essential for any LBZ, LMM or LML and goes hand-in-hand with monitoring 07-13 Sierra Allison 1000 transmissions, especially when these diesel 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 take accurate readings from 80° to 260° Fahrenheit.

The GM Allison 1000 Transmission Line T-Fitting Adapter allows the installation of a 1/8-27 NPT transmission temperature sensor directly onto the 5/8” transmission cooler feed line for extremely accurate readings. This GM Duramax Transmission Cooler Line T-Fitting Adapter includes (1) T-fitting housing with 1/8-27 NPT sensor port, (2) compression nuts and (4) cutting rings that ensure a tight, leak free seal. This T-fitting adapter is manufactured from high quality carbon steel with a tough nickel zinc coating that prevents rust over long term use.

The 1500° F Pyrometer EGT Gauge is essential for anyone driving a 2007-2013 Sierra 2500HD/3500HD who is pushing for maximum output out of their 6.6 Duramax diesel engine, delivering readings from 0 to 1500 degrees Fahrenheit. This GMC Sierra EGT gauge will ensure that your exhaust gas temperature is not running too hot which could result in turbo failure. A 6.6 Duramax EGT gauge is considered one of the most important LBZ, LMM or LML turbo diesel gauges. Readings up to 1500° apply to any 07-13 GMC truck, with this gauge typically being enough to cover the range.

The 30 PSI Fuel Pressure Gauge for the 6.6 Duramax displays readings from 0 to 30 PSI, and is the right gauge for any Sierra since they run on lower fuel pressure. 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. The first step for installation is making sure that your Duramax has an aftermarket lift pump. The second step is installing this Duramax fuel pressure gauge directly into the aftermarket lift pump for accurate readouts.

Note: When installing this gauge to a GM Duramax engine, an aftermarket lift pump is required for this gauge to function properly. Duramax engines do not have this lift pump to supply fuel to the engine. By adding it, you’ll experience a constant and steady fuel pressure, resulting in increased fuel efficiency, better throttle response, and a smoother idle.
