(1969-72) Underhood Cover and Insulation GMC

QuietRIDE is proud to introduce AcoustiHOOD, the next solution in our “holistic” approach to controlling automotive NVH. This new product is a two-part underhood cover and insulation kit that not only dresses up the engine, but also stops the vibration and noise created by large, minimally supported hood panels--noise that is air-borne and carried into the passenger cabin. Each product is patterned and modeled on an OEM hood, so that it is year, make and model specific and fits exactly as it should. The HeatShield Thermal Acoustic insulation panels are designed to fit between the structural ribs of the hood to stop vibration. The high-temperature ABS panel covers and protects the insulation. It also conceals the underhood rib structure and the blemishes that come as a result of exterior body work. While the hoods on older vehicles of the 1950s and 60s are much like kettle drums, the hoods of newer vehicles are much more structurally supported. Depending on the size, shape and structural integrity of the hood, AcoustiHOOD will reduce the transfer of air-born noise as much as three to five decibels on average. While that may not sound like a lot, it really works out to about a 25 percent reduction in automotive generated noise that buffets the windshield, dramatically impacting the comfort of the passenger cabin. What's Included in an AcoustiHood kit: AcoustiHood Under Hood Covers include heatshield barrier insulation panels to protect painted surfaces and to reduce the vibration and noise produced by these large body panels from entering the passenger cabin. Under Hood kits are year, make, and model specific, pre-cut and ready to install, and come with a hardware kit and illustrated installation instructions. Where possible, the manufacture uses factory hood insulation mounting holes. Some hoods will require additional mounting holes. Instructions for drilling mounting holes and a “drill stop sleeve” are included in each kit.
