The Speedhut Gauges A-299 Speedbox converts a GPS or vehicle speed sensor (VSS) signal into a mechanical drive output for speedometer applications. This electronic-to-mechanical converter is designed for installations where a modern GPS or VSS signal must operate a traditional mechanical speedometer, helping bridge the gap between updated vehicle electronics and classic gauge systems. The unit features a 7/8-18 output thread for connection to a compatible mechanical speedometer cable or drive assembly.
The Speedbox accepts a GPS or VSS input and produces the mechanical output required by supported speedometer systems. It is well suited for custom vehicle builds, restorations, gauge upgrades, and applications where the original mechanical speedometer drive is no longer available or cannot be connected to the transmission. By using an electronic speed signal rather than a transmission-mounted mechanical drive, the Speedhut Gauges A-299 can provide a practical installation option for vehicles with electronic speed sensors, GPS-based speed information, or modified drivetrains.
Constructed with a black plastic housing, the A-299 is designed for straightforward integration into a vehicle’s speedometer system. Verify signal compatibility, cable requirements, and output rotation before installation to ensure proper operation with the selected gauge and vehicle wiring. The 7/8-18 output thread should be matched with the appropriate mechanical cable or adapter for a secure connection. The Speedhut Gauges Speedbox is supplied as an individual converter and provides a focused solution for converting GPS or VSS speed data to a mechanical speedometer drive.
