Construction & Design

The DEI Sound Deadening Headliner Kit is crafted from high-quality open cell polyurethane foam, known for its excellent sound absorption and vibration damping properties. This material is engineered to withstand the rigors of daily driving and off-road conditions while maintaining its effectiveness over time.
