3-3/8in Ultra-Lite Elec. 120MPH Speedometer

The AutoMeter 3-3/8in Ultra-Lite Electronic 120 MPH Speedometer is designed for street machines, performance builds, and custom hot rods where both weight savings and accurate speed indication are essential. This speedometer is perfect for those swapping modern engines into classic chassis, upgrading outdated mechanical gauge clusters, or building restomods from scratch.

This electronic speedometer reads input from a standard vehicle speed sensor (VSS), eliminating the complications of mechanical cables and allowing for seamless integration with modern engine management systems and standalone ECUs. Its compact 3-3/8-inch diameter makes it suitable for small gauge pods and custom dashboard layouts. The electronic design ensures instantaneous needle response with zero lag, providing real-time speed feedback.

Enthusiasts restoring classic vehicles, builders working on LS/LT engine swaps, and hot rod fabricators will find this speedometer invaluable. The 120 MPH face and stepper motor mechanism guarantee durability and consistent performance across temperature extremes, making it ideal for high-output engine bays.
