The Hushmat Year, Make, and Model Floor Sound Deadening and Thermal Insulation Kit covers 100 percent of your vehicle's floor from the pedals back to the rear seat including the transmission tunnel.

The floor pan of your Pick Up is large and the exhaust passes directly underneath it. Engine and exhaust heat and noise pass right into the cab.  If you have off-road or rigid tires the road noise is almost unbearable even after a short drive. Talking on your cell phone or having a conversation with another passenger is a challenge. HushMat sound deadening and thermal insulation enhances the Pick-Up experience with the easiest to install sound deadening material. Your Pick-Up is fun to drive, but the engine gets hot. There is over 200 degrees of heat cooking your firewall and floor pan. Your engine, headers, manifold, and exhaust generate tremendous heat that transfers to the metal firewall and floor and this heats up your Pick-Up interior. It can create a very uncomfortable ride, especially in the summer. This also forces your AC system to work harder to reduce and maintain comfortable temperatures inside your Pick-Up. HushMat automotive insulation is the solution to REDUCE thermal transfer into your interior. HushMat proprietary USA manufactured chemistry makes the automotive heat shield dissipate this heat, insulating your interior and improving the load on your HVAC system which makes your Pick-Up significantly cooler in the summer and warmer in the winter.  HushMat is proven in an independent study to lower this temperature by over 40 percent. Nothing beats the heat and noise like HushMat. HushMat sound deadening and thermal insulation material leads the automotive industry in ease of installation. HushMat has packaged this kit specifically for your Pick-Up floor pan to provide 100 percent insulation coverage. There are no holes in the material and no puzzle pieces to put together.  Simply apply the HushMat material as shown in the Installation Guide. HushMat auto insulation material reduces road noise, exhausts noise, and insulates your Pick-Up for a more comfortable ride for you and your passengers.
