Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

This listing may contain a product with transport restrictions. Items containing oils, additives, aerosols, adhesive or other liquid/chemical-based products may be subject to shipping restrictions depending on their current warehouse location, carrier requirements, and applicable transport regulations.

Some liquid and aerosol products are restricted for air freight or certain road freight routes and may require alternative transport methods or dispatch from a specific warehouse.

Sound Deadening Mats, Thermal and Acoustic, Floor, Self-Adhesive, Regular Cab, Chevy, GMC, Kit

Insulate your interior from unwanted heat and noise with a Boom Mat thermal and acoustic interior kit. These versatile 3-step packages include plenty of Boom Mat material to cover flat sheet metal and/or door skins, eliminating most structural vibrations, rattles, and squeaks. Next, the can of Boom Mat Spray-On lets you dampen the noise in hard-to-reach areas, like fender wells, the trunk interior, undercarriage, and other body panels. Finally, you can apply the Under Carpet Lite insulating fabric over firewalls and floor boards to resist nearly 85 percent of the heat transferred from engine and exhaust components—while providing additional sound deadening. Boom Mat thermal and acoustic interior kits are economical, easy to install, and work with any vehicle. Choose the coverage size needed for your application.
