The Differential Temperature Gauge tracks heat at the differential so you can monitor drivetrain performance under real conditions. Built for applications where load and sustained use generate heat, it helps you catch rising temperatures early during towing, off-road driving, or performance use. Includes a matched temperature sender for accurate, consistent readings across a wide range of setups. A precision stepper motor keeps the needle smooth and steady—no bounce, no guesswork. Built with a durable housing and solid aluminum bezel, it’s made for demanding conditions and long-term use. Made in the USA and backed for life.
