It reduces interior noise by 3 to 4 decibels, enhances audio clarity, and provides thermal insulation to keep your cabin comfortable year-round. This kit includes both headliner and side window liners, delivering comprehensive sound and temperature control for a superior driving experience. ## Description Riding in a Jeep is great fun except for the truck's propensity for interior noise that makes it difficult to engage in conversations or even enjoy vehicle audio systems. Now there is an easy solution. Boom Mat's Jeep Wrangler Sound Deadening HeadLiner provides a simple pre-shaped 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. Installed Boom Mat'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 overall interior acoustics so Jeep occupants can enjoy audio system and have conversations without excessive and irritating noise distractions. Review: Heinously overpriced - Fitment is okay. Product is thinner than expected. Maybe 1". For the price youd be way better off getting a roll of 2" MDF and some 2 sided tape. Easily 1/2 the price with better results. Wouldn't recommend. Review: work well - best investment ever. ## Features - Precut for an exact fit with easy peel and stick installation - Headliner reduces noise levels 3 to 4 decibels and improves interior acoustics - Insulates in the winter and keeps interior cooler in the summer - Makes it easier to have conversations and enjoy your favorite music - Combination kit includes headliner and side window liners ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08D6QPCPK | | Best Sellers Rank | #76,789 in Automotive ( See Top 100 in Automotive ) #152 in Automobile Insulation | | Brand | Design Engineering | | Brand Name | Design Engineering | | Coverage | Full headliner coverage | | Customer Reviews | 4.2 out of 5 stars 78 Reviews | | Global Trade Identification Number | 00607078502902 | | Included Components | Boom Mat Sound Deadening HeadLiner Kit | | Item Type Name | Original Boom Mat Sound Deadening HeadLiner Kit Compatible with 4-Door Jeep Wrangler JK (2011-2018) | | Item Weight | 3.63 kg | | Manufacturer | Design Engineering, Inc. | | Manufacturer Part Number | 50290 | | Material | Rubber Aluminum | | Material Type | Rubber Aluminum | | Model Number | 50290 | | Number of Packs | 1 | | Recommended Uses For Product | Sound Insulation, Thermal Insulation | | Recommended uses for product | Sound Insulation, Thermal Insulation | | UPC | 607078502902 | | Unit Count | 1 Count | ## Product Details - **Brand:** Design Engineering - **Global Trade Identification Number:** 00607078502902 - **Manufacturer:** Design Engineering, Inc. - **Material:** Aluminum, Rubber - **Number of Packs:** 1 ## Images ![50290 Black Original Boom Mat Sound Deadening HeadLiner Kit Compatible with 4-Door Jeep Wrangler JK (2011-2018) - Image 1](https://m.media-amazon.com/images/I/61fUUkPjvLL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐ Heinously overpriced *by W***R on 2 February 2025* Fitment is okay.
