2018–2026 Jeep Wrangler Unlimited JL

Part #: 50180

Overview

The DEI Boom Mat Headliner Kit is a precision-engineered sound deadening solution designed specifically for the Jeep Wrangler Unlimited JL models from 2018 through 2026. This pre-shaped, peel-and-stick kit enhances the interior aesthetics of Jeep hard tops while significantly reducing unwanted exterior noise and vibrations. Ideal for Jeep enthusiasts who want to improve cabin comfort, the Boom Mat Headliner Kit also provides insulation against harsh weather conditions, making every ride quieter and more enjoyable.

Jeep Wranglers are known for their rugged off-road capabilities, but their open design and hard top construction often lead to elevated interior noise levels. The Boom Mat Headliner Kit addresses this challenge by lowering noise by 3 to 4 decibels, a noticeable improvement that enhances in-cabin acoustics and allows for clearer conversations and better audio system performance.

Construction & Design

The Boom Mat Headliner Kit is constructed from high-quality open cell polyurethane foam, chosen for its excellent sound absorption and thermal insulation properties. The foam is treated with a polymer surface finish that enhances durability and ensures the material maintains its shape and effectiveness over time. Each piece is precision-cut to match the contours of the Jeep Wrangler Unlimited JL hard top interior, allowing for a seamless fit without the need for trimming or modification.

This engineered design not only dampens noise but also reduces radiant heat transfer from the roof, contributing to a more comfortable cabin environment during hot weather. The white finish adds a clean, factory-like appearance that integrates well with the Jeep’s interior styling.

Performance & Sound

Tested to reduce noise levels by 3 to 4 decibels, the Boom Mat Headliner Kit delivers a significant improvement in interior sound quality. This reduction in ambient noise makes it easier to hold conversations and enjoy music without raising the volume excessively. By controlling vibrations and blocking external sounds, the kit enhances the overall driving experience, especially on highways and rough terrain where wind and road noise can be intrusive.

Installation is simple and user-friendly thanks to the pre-shaped peel-and-stick design. The kit includes all necessary pieces to cover the entire headliner area of the Jeep Wrangler Unlimited JL hard top. No special tools or modifications are required, making it an ideal upgrade for DIY enthusiasts or professional installers alike.
