Description Protect your 1999-2007 Chevrolet Silverado or GMC Sierra Extended Cab with WeatherTech’s comprehensive FloorLiner DigitalFit set. This classic body style generation remains incredibly popular, and this three-piece floor protection system delivers absolute interior coverage. Digital laser measurements ensure perfect fit while the rigid HDTE construction completely lines interior carpet up the front, back, and sides of your footwells. Key Features WeatherTech’s patented High-Density Tri-Extruded (HDTE) material provides a rigid core for exceptional strength while offering surface friction against the carpet and tactile feel on the surface. Advanced surfacing creates channels that carry fluids and debris to lower reservoirs, minimizing movement while driving. The raised lip design contains spills and protects factory carpet from damage and staining that diminishes resale value. Components This complete set includes front over-the-hump coverage for driver and passenger footwells plus extended rear floor coverage designed specifically for Extended Cab configurations with underseat storage. All pieces feature integrated retention systems compatible with factory floor mat hooks. Rear coverage extends under rear seats for comprehensive protection.

WeatherTech provides detailed instructions with each set for optimal fit. Our Take At Strictly SVDs, the classic body GMT800 Silverado and Sierra remain workhorses in our customer base. Many of these trucks have 200,000 miles and are still going strong with proper maintenance. WeatherTech FloorLiners protect interiors that have already survived decades of use while maintaining what condition remains. The Extended Cab rear coverage is particularly valuable as these areas tend to accumulate significant debris over time. American-made quality with a 3-year warranty makes this an excellent investment in your classic GM truck.
