When you're doing a full interior restoration on your FSJ, the door kit won't cut it alone. The HushMat Ultra Bulk Kit gives you 58 square feet of peel-and-stick sound deadening and thermal insulation in one box - enough to do the entire floor of a Wagoneer, or the floor and roof of a J-truck in one shot.

Thirty 12x23 sheets of stealth black butyl rubber go on without tools, adhesives, or surface prep. The self-adhesive backing bonds directly to oily cold-rolled steel, E-coat, and most plastics - so you're not cleaning and prepping bare metal before you start. Cut to fit with scissors or a razor knife, press into place, and done. The larger rectangular sheets are ideal for flat floor pans and wide tunnel surfaces where the smaller door kit squares would mean unnecessary extra cutting.

HushMat Ultra kills road noise from 0-1000 Hz and cuts heat transfer by up to 40%. It handles everything from -30F to 550F without deforming, sagging, or losing adhesion - critical for the tunnel and firewall areas of an FSJ where exhaust heat is a real factor. Rated #1 by Restorer Magazine, OEM-approved by GM, Ford, and Chrysler, and made in the USA.
