1978-88 Chevrolet G Body cars with the six-round gauge clusters can also enjoy the perks of HDX! Not for the sweep-style cluster, this bolt-in package affords six analog readings, stock-location turn signals and a pair of TFT message centers. Use your stock housing, blackout plate and front bezel for a painless upgrade! Choose from Black or Silver Alloy face styling. Available with your choice of black or silver alloy gauge-face styling, each HDX system allows the user to select independent illumination colors for the gauge readings and needles, as well as the message centers. Calibration and personal settings are manipulated with the built-in, capacitive-touch buttons, or the available Bluetooth app for Apple and Android devices. Each needle hub is black nickel plated spun-aluminum to match the buttons. All HDX instrument systems feature dead-faced indicators (turn signals, high beam, check engine, cruise control, parking brake, plus two user-definable), and a red, settable warning light for each gauge. With our central control box, installation is greatly simplified with vehicle-harness sourced signals and supplied, solid state sending units connecting cleanly to their respective terminal.
