5in S/C II In-Dash Speedo 160MPH

The 5in S/C II In-Dash Speedo 160MPH is a direct-fit analog speedometer built for enthusiasts who demand precision instrument cluster upgrades over factory electronics. This electric speedometer replaces OEM units in classic and restomod builds where reliability, readability, and customization matter more than digital displays. Designed for vehicles where accurate speed monitoring and classic aesthetics align, this gauge integrates seamlessly into 5-inch dash openings and delivers real-time velocity feedback without the complexity of modern solid-state sensors.

This Sport-Comp II speedometer features a 160 MPH maximum scale with programmable calibration, allowing tuners to match engine speed to exact wheel diameter and tire size specifications. The analog needle design eliminates the lag inherent in some electronic instruments, while the black face with high-contrast markings ensures legibility in varied lighting conditions. Electric operation powers the gauge from standard 12V automotive electrical systems, and the programmable function lets you dial in accurate readings regardless of rear-end gear ratio or final-drive configuration—critical for forced-induction and modified powerplant applications where stock calibration falls short.

Hot rod builders, drag racing teams, and street performance shops benefit most from this upgrade when converting to modern fuel injection or standalone engine management that requires external speedometer input. The 5-inch diameter fits standard single-gauge dash panels common in 1960s–1990s American muscle cars, street rods, and vintage truck restorations. Installation requires 12V power, ground, and a programmable speed signal input—typically sourced from transmission output shaft sensors, wheel-speed sensors, or ECU outputs on turbocharged and supercharged builds where aftermarket boost control demands precision monitoring.
