Classic Instruments Speedometer/ Quad Gauge Display LS Chevy/ GMC Trucks 47-53 AutoCross Gray

Equip your 1947-1953 Chevy or GMC truck with modern instrumentation using this Classic Instruments AutoCross gray speedometer and quad gauge package for LS engine applications. The all-electric system combines a 4-5/8” speedometer with a matching quad gauge that displays fuel level, oil pressure, water temperature, and voltage. AutoCross gray gauge faces, stainless steel low-step bezels, and flat glass lenses provide a coordinated appearance while maintaining the original dashboard layout.

ZST-equipped instruments operate without external control boxes, reducing the number of components required behind the dashboard. A built-in ECM signal filter switch supports electronic engine signal compatibility, while the snap-in wiring harness provides organized electrical connections. The package also includes the necessary sending units, a model-specific trim ring, and mounting hardware. The fuel gauge operates with a 240-33 OHM resistance range.
