DEI Boom Mat Complete Headliner Kit for 2011-2018 Jeep Wrangler JK 4-Door - Gray Original Finish
Turn your Jeep's cabin into a quieter, more insulated space with the DEI Boom Mat Complete Headliner Kit, designed exclusively for 2011-2018 Jeep Wrangler JK 4-Door models equipped with factory hardtops. This pre-cut, peel-and-stick system applies directly to the hardtop's interior, cutting road noise and vibrations by 3 to 4 decibels for clearer conversations and better audio playback. It also blocks radiant heat from the roof, keeping the interior cooler during hot drives and shielding against external weather elements for year-round comfort.
Crafted from open-cell polyurethane foam with a durable polymer surface treatment in gray original finish, this kit matches the factory look while delivering reliable sound deadening and thermal control. Jeep enthusiasts choose this kit for its direct fit and straightforward installation that requires no custom cutting one person can handle the front panels, though two are recommended for the larger rear sections. The result is a noticeable drop in distractions, letting you focus on the trail ahead.

Hard Top Accessories
Hard top accessories provide the hardware, seals, and functional components that keep removable hard top panels working correctly on Jeep Wranglers, Ford Broncos, and other vehicles with removable roof sections. The weather seals, door surround gaskets, hinge hardware, and lift support struts that support and seal a hard top all degrade with UV exposure, temperature cycling, and repeated removal and installation, eventually causing water leaks, wind noise, and sagging or misaligned panels. Quality replacement seals and hardware restore the hard top's weather protection and structural integrity without the expense of replacing the entire top. For owners who frequently remove their hard top for open-air driving, proper storage accessories including cradles, carts, and hoists are essential for protecting the panel and making the removal process safe and manageable. Popular Upgrades Jeep Wrangler JL and JK hard top weather seal kits from Mopar and Rugged Ridge are the most popular items...
