This component is a protective and often decorative covering for the dashboard of a specific series of General Motors trucks and SUVs produced from 1973 to 1987 (and Blazers/Jimmys through 1991). It serves to shield the underlying dashboard material from sun damage, prevent cracking, and enhance the interior aesthetic of these vehicles. The design is tailored to fit the distinctive, angular dashboard shape prevalent in those models.
Its significance lies in preserving the integrity and appearance of the vehicle’s interior. Over time, exposure to UV rays and temperature fluctuations can cause significant deterioration of the original dashboard. This protective layer mitigates these effects, maintaining the vehicle’s value and contributing to a more comfortable driving experience. Historically, these items were often made of durable vinyl or plastic, though modern aftermarket versions may utilize updated materials with improved resistance to cracking and fading.
