Rebuilt and pre-programmed replacement instrument cluster compatible with 2003, 2004 GM, GMC, or Chevy vehicles. These instrument clusters are notorious for having the gauges stick, giving incorrect readings, or not working at all. We offer a refurbished cluster, replacing not only the components of the faulty gauge, but rebuilding ALL of the gauges with upgraded components to ensure proper function. LED Upgrade: We offer an OPTIONAL upgrade of a backlight with LED lighting for the instrument clusters. LED lighting has a much longer lifespan, is more efficient, and operates at a cooler temperature. Although most LEDs are highly directional, which can cause bright and dark spots in a gauge cluster, our LEDs are specially designed to provide a 360-degree distribution of the light. This provides more even backlighting comparing to the conventional directional LEDs. If you would like LED backlighting for your instrument cluster, simply select the upgraded option from the drop-down menu during the customization process.
