DEI Boom Mat Regular Cab High Hump Floor Insulation Kit - Chevrolet C10 / K10 / GMC C1500 1973-1987

Under Carpet Lite is a half inch multi-layer polyester and fiberglass composite that does two jobs at once: it blocks the engine, exhaust, and road heat coming up through a squarebody floor pan, and it works as a sound decoupler that keeps road, tire, and drivetrain noise from transmitting straight into the cab. At roughly 0.23 lb per square foot it adds almost nothing to the truck, and it stays flexible enough to lay into the contours of a floor rather than bridging them. This kit arrives pre-cut for the regular cab high hump floor, so there is no templating and no trimming a bulk sheet around the transmission tunnel and seat mounts. Made in the USA.
