Construction & Design

The trim kit features open cell polyurethane foam, a material known for its excellent sound absorption and thermal insulation properties. This foam is treated with a durable polymer coating that protects against moisture, wear, and environmental factors, ensuring long-lasting performance. The gray finish is designed to blend seamlessly with Jeep interiors and DEI headliner kits, providing a clean, professional look.

Each piece is molded to fit the contours of the rear side window trim area precisely, allowing for a snug fit that enhances both function and aesthetics. The combination of materials and design results in a product that not only reduces noise but also contributes to a more comfortable cabin environment by minimizing heat transfer.

Installation is straightforward and designed to integrate smoothly with your existing headliner setup. The kit fits directly onto the rear side window trim areas of Jeep Wrangler models from 2007 to 2018 without requiring any cutting or modifications. This ensures a hassle-free upgrade that maintains the integrity of your vehicle’s interior components.

For best results, it is recommended to install this trim kit in conjunction with a DEI headliner kit, although it can also be used independently to improve sound deadening and insulation in the rear cabin area.
