99-07 GM P/U Rear Mud Flaps

The 99-07 GM P/U Rear Mud Flaps are a proven investment for full-size pickup owners who spend serious time on job sites, gravel roads, or challenging terrain. These rear mud flaps protect your truck's paint, undercarriage, and the vehicles behind you from road spray and debris—a real-world necessity rather than a cosmetic upgrade. Whether you're running a work truck or a weekend hauler, this WeatherTech accessory addresses a genuine vulnerability that stock pickups leave exposed.

WeatherTech's engineering focuses on durable thermoplastic construction that resists UV degradation and extreme temperature swings—critical for components that endure constant sun exposure and wet climates. The rear mud flaps mount securely to the wheel well area using factory attachment points, requiring no welding, drilling, or permanent modification to your frame. The design creates a barrier that catches gravel, sand, and salt spray before they impact your pickup's lower panels and trailing vehicles, while the flexible material absorbs minor impacts without cracking.

These mud flaps fit 1999 through 2007 Chevrolet and GMC full-size pickups (C/K, Silverado, and Sierra models) with bolt-on installation that typically takes under 30 minutes per side. Mechanics and fleet managers recognize them as preventive maintenance—the cost of a set of mud flaps is negligible compared to repainting a pickup bed or replacing undercarriage components damaged by road salt and debris. Installation requires no special tools, and the OEM-style appearance ensures no visual compromise to your truck's profile.
