Design Engineering Inc Parts

Design Engineering, Inc. (DEI) makes Boom Mat headliners and heat and sound control products for the Jeep Wrangler, helping to quiet the cabin and block heat that radiates through the hardtop. For more than 25 years, DEI has manufactured and distributed premium heat and sound control products worldwide, with a focus on engineering and customer satisfaction. DEI's Boom Mat headliner kits are pre-cut to fit the factory hardtop on the Wrangler JL and Wrangler JK, in both 2-door and 4-door versions. The headliner absorbs road and wind noise and adds insulation that helps keep the cabin cooler in summer and warmer in winter, while giving the inside of the top a clean, finished look. Beyond headliners, DEI offers a range of heat shielding and insulation products for engines, exhausts and floors, so you can tackle heat and noise throughout your build.
