DEI Introduces Jeep® Gladiator (JT) Headliner/Side Window Kit

Designed to add insulation and sound deadening
for improved interior comfort and sound quality

Avon Lake, OH, (October 24, 2019) – The Jeep® Gladiator open air pickup is one of the most exciting vehicles to be introduced by Jeep in years, and now DEI, the leader in automotive heat and sound control, is hot on the trail by introducing a JT headliner kit to improve interior comfort and sound quality. Designed with a dual purpose of sound deadening and insulation, the headliner kit greatly reduces distracting road noise while insulating the interior from extreme heat or cold. Rides on or off the trail are much more enjoyable and the final product is a professional look that will add to resale value. 

Made from marine grade foam that resists mold and mildew, the seven-piece Jeep headliner is custom cut and CNC machined for a perfect OE fit. Installation is easy.

Simply peel, position in place and stick-on for a secure fit. DEI’s Gladiator kit is available now in two finish options – Original or Leather Look. Original finish is available in three attractive colors: black, gray and white.  Leather Look is available in black or gray.
