Gauge Components

Gauge Components

Automotive gauge components are the hardware foundation that makes every aftermarket gauge installation work reliably, including sending units, fittings, tubing, wiring harnesses, electrical connectors, and mounting hardware that connects the gauge head to the sensor point on the vehicle. A gauge is only as accurate and reliable as its supporting components, and using quality sending units from brands like Autometer, VDO, and Speedhut ensures the electrical signal reaching the gauge accurately represents the actual oil pressure, coolant temperature, fuel level, or boost reading. Gauge components range from simple weld-in bung fittings for oil temperature probes to complete electrical harness kits that handle all the wiring for a multi-gauge cluster installation. Understanding the correct sender type and wiring configuration for your specific gauge brand is essential for accurate readings and long-term reliability.

Gauges & Pods

Gauges & Pods

Performance gauges and gauge pods form a complete driver information system for any modified or performance vehicle, combining accurate instrument measurement with a mounting solution that keeps critical engine data visible without cluttering the interior. Gauge kits that bundle the gauge head with a compatible pod create a finished, coordinated installation that looks intentional rather than improvised. Whether monitoring boost on a turbocharged build, oil pressure on a high-revving naturally aspirated engine, or exhaust gas temperature on a diesel truck that tows near its limit, the combination of a quality gauge and a proper pod mount is the correct approach. Both A-pillar and dash pod solutions are available for the most popular domestic and import performance vehicles. Popular Upgrades Autometer Sport-Comp and Ultra-Lite gauge and pod bundles for the Mustang, Camaro, WRX/STI, and F-150 are the most popular combination purchases, providing a matched gauge and vehicle-specific A-...
