AutoMeter - Ultra-Lite 2-1/16" Differential Temperature Gauge - 4349

When your vehicle leaves the pavement or undergoes heavy duty use, monitoring differential temperature becomes critical. This AutoMeter Ultra-Lite gauge measures from 100-250 °F and fits into a 2-1/16″ (≈ 52 mm) mounting hole.

It features a rugged air-core meter movement for fast, accurate readings, and includes a 1/8″ NPT differential temperature sender, along with 3/8″ and 1/2″ NPT adapter fittings, mounting hardware, bulb/socket assembly with red and green covers, and detailed instructions.

The Ultra-Lite design uses lightweight aluminum construction for minimum weight and maximum durability, making it suitable for off-road, racing, or heavy-use vehicles.
