2-1/16in S/C Differental Temp Gauge

The AutoMeter 2-1/16in Sport-Comp Differential Temperature Gauge (Model 3349) is a compact, electric analog temperature gauge designed to monitor differential fluid temperatures in high-performance and motorsport applications. This short-sweep gauge displays temperatures from 100 to 250 degrees Fahrenheit with precision, helping drivers maintain optimal gear oil conditions during aggressive driving or towing operations.

The 2-1/16-inch diameter dial fits standard automotive gauge clusters and aftermarket dash panels while maintaining AutoMeter's reputation for accurate, reliable instrumentation. The black face with white lettering provides clear visibility in all lighting conditions. As an electric gauge, it connects to an external differential temperature sender, allowing real-time monitoring of fluid temperature as it changes under load. The short-sweep needle movement delivers quick, responsive feedback—critical for detecting temperature spikes before differential damage occurs. This analog design integrates seamlessly into both classic restorations and modern performance builds without requiring complex digital interfaces.

Differential temperature monitoring is essential for vehicles regularly subjected to heavy towing, track duty, or sustained high-load operation. Gear oil viscosity breaks down under extreme heat, reducing lubrication effectiveness and accelerating wear on ring-and-pinion gears. By watching differential temperature in real time, drivers can adjust driving habits, reduce load, or schedule maintenance before catastrophic failure. This gauge is favored by off-road enthusiasts, tow-rig operators, and performance drivers who demand visibility into drivetrain conditions. AutoMeter's Sport-Comp line balances affordability with durability, making this temperature gauge a practical upgrade for any serious powertrain application.
