The AutoMeter Gauge Speedo 3 3/8in 120mph Electronic Programmable with Wheel is a precision instrument cluster upgrade designed for serious automotive enthusiasts who demand accurate, real-time speed monitoring in street rods, custom builds, and high-performance vehicles. This electronic speedometer replaces outdated mechanical gauges with modern reliability, offering programmable functionality that adapts to various drivetrain configurations and tire sizes. Whether you're running a classic hot rod with a modern engine swap or a contemporary project car with custom gearing, this gauge delivers the responsiveness and accuracy modern drivers expect.

Built with AutoMeter's reputation for durability, the 3 3/8-inch diameter face provides excellent visibility on any dashboard, while the electronic design eliminates mechanical cable wear and calibration drift common in vintage systems. The 0–120 mph range covers street and light performance applications, and the programmable feature allows calibration to match your specific wheel diameter and final drive ratio—critical when wheel size or gear ratios change from factory specs. The included wheel sensor interface ensures direct feedback from your vehicle's speed signal, providing dependable readings without the lag or inaccuracy of older mechanical designs.

This gauge suits restomod builders, street rod fabricators, and anyone upgrading a classic vehicle with modern powertrain components who needs a speedometer that reflects actual speed regardless of non-OEM tire or gear selection. Installation requires a clean 12V power supply and connection to a speed sensor output; compatibility depends on your vehicle's electrical system and available sensor signal. At 0.95 lbs with compact 6.6 x 4.9 x 7.3-inch dimensions, it mounts easily in standard gauge clusters or custom panels, making it an essential tool for any comprehensive dashboard modernization project.
