?? DESIGN ENGINEERING INC: We have over 25 Years of Innovation experience. Dale Markley and his wife Nancy founded DEI in 1995 with a vision of developing solutions for the racing and performance industry's ongoing struggle with power-robbing heat issues. The business was started in a small space in Cleveland, Ohio and within a few years has doubled in size. Today, Dale's son David is at the helm making DEI bigger, stronger, and cooler than ever. ?? PRODUCT DESCRIPTION: Riding in a Jeep Gladiator is great fun except for the truck's propensity for interior noise that makes it difficult to enjoy conversation and sound systems. DEIs new Jeep Gladiator Sound Deadening Headliner provides a simple pre-cut peel and stick kit that dresses up the interior of Jeep hard tops while minimizing annoying outside noise and vibrations while insulating from exterior weather conditions. DEI's new Sound Deadening Headliner has been tested to reduce noise levels from 3 to 4 decibels. This is a significant change in sound level that will improve the overall interior acoustics so Jeep occupants can enjoy their audio system and have conversations without excessive distractions. ?? BENEFITS: Insulate your interior from heat and cold while improving the efficiency of your A/C and heater. Each easy to install pre-cut peel and stick panel compliments the interior finish and style. We use open cell polyurethane foam to minimize annoying outside noise and vibrations. The complete kit is designed for any Jeep Gladiator JT 2020-up. Each headliner reduces noise levels by 3 to 4 decibels, reduces radiant heat and cold from the roof exterior, and provides a significant change in noise level making it easier to have conversations & enjoy your favorite music. ?? MATERIAL: We use Open Cell Polyurethane Foam with a Premium Textured Surface. ?? SPECIFICATIONS: Model: JT Doors: 4-Door Kit: Complete Kit Finish: Original Color: Black Old Part Number: 050183
