X-Series GPS Speedometer Gauge 0-160mph

The X-Series GPS Speedometer Gauge 0-160mph from AEM Electronics is purpose-built for drivers and enthusiasts who demand accurate, real-time speed monitoring without relying on factory instrumentation. Whether you're tuning a high-performance vehicle, validating ECU calibration, or simply upgrading your dash cluster, this digital gauge eliminates the guesswork inherent in mechanical speedometers. It's the go-to choice for race teams, dyno operators, and serious modifiers who need verified velocity data during acceleration runs and track sessions.

The GPS-based architecture delivers independent speed verification with zero mechanical linkage or electrical signal manipulation—critical when factory speedo output is unreliable or disabled during engine management reprogramming. AEM's X-Series employs satellite positioning to calculate instantaneous velocity, offering a 0–160 mph range that accommodates everything from street cars to high-powered motorsports platforms. The compact 5.3 x 5.3 x 5.5-inch form factor and lightweight 1 lb construction integrate seamlessly into custom dash pods, A-pillar mounts, or OEM cluster replacements without adding significant weight or thermal load to the vehicle.

Mechanics and tuners leverage this gauge during cold-start diagnostics, turbo boost verification, and transmission shift-point validation when stock instrumentation cannot be trusted. The digital display eliminates parallax error and needle drift common to analog gauges, ensuring consistent readings across multiple test runs—essential for A/B comparisons during carburetor jetting, fuel mapping, or suspension tuning. Installation requires only a clean 12V power supply and antenna placement with unobstructed sky view; no wheel-speed sensors, OBD modules, or CAN-bus integration necessary, making retrofit work faster and more reliable across all vehicle platforms.
