The Classic Instruments CT88DOE direct-fit package modernizes the 1988-94 OBS Chevy truck dash with an all-electric cluster that drops into the stock diffuser and lens. It combines a 140 MPH speedometer, 8 K RPM tach, fuel, oil, temp, and volt gauges with an OLED (Organic Light-Emitting Diode) odometer/trip display and optional digital speed readout. Hybrid LED lighting blends perimeter glow with full back-lighting for even nighttime visibility, while built-in check-engine, high-beam, shift, and dimmer LEDs add convenience. Zeus Speedometer Technology is onboard—no external box needed—and the programmable fuel gauge works with nearly any sender.
