We unbderstandthat you want your Chevy truck to be as comfortable as possible, and that’s why we recommend the installation of a sound deadening kit! Each of the four (4) pieces is manufactured from Ethyl Vinyl Acetate (EVA) and die-cut for a precise, exact fit. They’ll apply directly to the floor of your truck’s cab, underneath the carpeting. It will help reduce road noise and vibrations and adds an extra layer against the elements.
