Are you looking to keep a close eye on the changing temperatures of your truck’s gear oil when towing heavy loads? Installing GlowShift’s Differential Temperature Gauge is electronically driven and will effectively read your vehicle’s diff temp from 100° to 250° Fahrenheit with the included 1/8-27 NPT temperature sensor and weld-in bung that install directly to the rear of the differential cover for extremely accurate readings directly from the source.

Why is a Differential Temperature Gauge important? Monitoring your truck’s differential temperature is extremely important because it directly affects the performance of the transmission and rear differential. If you are unaware of your vehicle’s differential temperatures and it happens to be running high, it could lead to premature wear and costly repairs.

This GlowShift 2 1/16” (52mm) Tinted 7 Color Diff Temp Gauge features a black gauge face with tinted lens, an illuminated red needle that sweeps 270° and utilizes GlowShift’s signature 7 Color LED through dial lighting. The 7 Color LED through dial lighting system allows you to easily select from 7 different solid color modes that include blue, green, red, white, purple, yellow and teal, as well as 2 color cycle modes that alternate through the featured colors. This allows you to easily match your gauge with your truck’s factory dashboard lights or to add a custom style to your interior. With the included color recall feature, you won’t have to worry about setting the gauge to your preferred color every time you power your truck on. Connecting this gauge to the factory headlight switch source allows the gauge to dim 30% for easier monitoring when driving at night.
