The SUPERIOR LABS SL043-1010 is a 43-inch mechanical tachometer drive cable designed for aircraft engine RPM indicator systems utilizing mechanically driven tachometers. The cable is used to transmit rotational movement from the engine accessory drive gearbox to a panel-mounted tachometer indicator.

This type of flexible tachometer cable is commonly installed in general aviation aircraft equipped with traditional mechanical RPM instrumentation, including legacy certified aircraft, experimental aircraft, and retrofit panel systems using Superior Labs (SLI), Stewart Warner, and compatible tachometer assemblies.

The SL043-1010 cable assembly features a flexible inner drive core within a protective outer sheath designed to withstand aircraft engine compartment vibration, routing bends, and temperature variations while maintaining accurate RPM signal transmission. The 43-inch length configuration is intended for installations requiring medium-length routing between engine and instrument panel locations.
