Installing a rear axle temperature gauge provides valuable insights into the health of your truck's rear axle. It allows you to detect overheating to protect against damage during towing or hauling, and to ensure the longevity of your rear axle. With this monitoring tool, you can drive with confidence, knowing that you're actively monitoring and protecting a crucial component of your truck's drivetrain. For an easy installation of the sending unit, install one of our Mag-Hytec differential covers, which already have a drilled and tapped port for the sending unit, along with many other features.

EV² electronic gauges include an integral programmable warning light, which may be activated if you select the checkbox above to add the programmer tool. The programmer can also be used to adjust the backlighting curve to perfectly match the factory dash lights, and can also adjust the amount of signal filtering/smoothing that the software performs.
