Construction & Design

The DEI Boom Mat Headliner Kit is engineered with high-quality open cell polyurethane foam that effectively absorbs sound waves and dampens vibrations.

The kit’s components are pre-cut and contoured to match the interior contours of the Jeep Wrangler Unlimited JL hard top, providing a seamless fit that looks factory-installed.

The black finish not only enhances the visual appeal but also contributes to the kit’s ability to block radiant heat from the roof, improving overall cabin comfort during hot weather. The materials used are lightweight yet robust, ensuring they do not add unnecessary weight or interfere with vehicle operation.
