Replacing the headliner in your truck will give you more than just a better looking interior. The headliner is a major source of interior noise in these trucks. Did you know that there are hollow chanels that start at the headliner area, travel down the rear door post, and out at the bottom of your truck? I have heard of road salt reaching the headliner area on a few ocations. I get into detail about how exactly to reduce noise caused by this in the article I inclued with every purchase.
