Classic Instruments 1978-88 G-Body Gauge Sets

Classic Instruments' 1978-88 Chevy G-Body direct-fit packages are all-electric clusters featuring a speedometer, tachometer, clock, and fuel, oil, temp, and volt gauges in an OE style. These instruments are available either with or without gear position indicator, and with or without overdrive gear indicator for use with any transmission. Hybrid LED lighting offers the feel of the original perimeter lighting and the visual benefits of back-lighting: even illumination and clear nighttime readability. Turn signals and high beam indicators are in the original locations, and each kit includes new check engine and high beam sockets with LED bulbs. Additional indicator bulbs are available for purchase.

These kits also include: a wiring harness, push-button speedometer calibration for ease of setup, a new acrylic lens, and built-in ECM signal filter switch. Save space with Classic Instruments' Zeus Speedometer Technology built-in, meaning the cluster requires no external control boxes and works directly with ECM or VSS signals. The fuel gauge is programmable for any ohm range with a selector switch on the back of the cluster, meaning the fuel gauge will work with the stock sending unit, any other factory sending units, or any Classic Instruments fuel sending unit. All other necessary sending units are included in a Classic Instruments GM sending unit kit. Install using your existing diffuser. The gauge sets also fit 1982-87 GMC Caballero.
