67-72 GM C/K 10-30 Serie s Truck Door Insulation

The 67-72 GM C/K 10-30 Series Truck Door Insulation by FLATLINE BARRIERS is a specialized thermal and acoustic damping material designed for classic Chevrolet and GMC light-duty trucks. This product is ideal for those restoring vintage work trucks or modernizing collector vehicles, as it effectively reduces road noise, minimizes heat transfer, and enhances overall cabin comfort.

Engineered to fit precisely behind door panels, this insulation does not interfere with window mechanisms, lock hardware, or door latch assemblies. The material is designed to absorb vibration frequencies common in vintage truck cab environments while maintaining flexibility in cold climates, making it suitable for seasonal use or long-term storage.

This insulation kit is perfect for owners restoring 1967–1972 GM C10, C20, C30, K10, K20, and K30 models, whether for daily driving or show trucks that prioritize comfort upgrades. Installation requires door panel removal, ensuring a seamless fit that enhances the driving experience.
