Protect your 2019-2021 GMC Sierra 1500 or Sierra Denali from road debris with the WeatherTech DigitalFit No-Drill MudFlap Kit. Designed for applications without the large original equipment splash guard, this black mudflap set helps shield vulnerable fender and rocker panel areas from stone chips, slush, dirt, and other debris that can contribute to exterior wear and corrosion. The contoured design is engineered specifically for the vehicle application, providing a clean, integrated appearance and dependable coverage.
The WeatherTech No-Drill MudFlap uses a Patent Pending QuickTurn hardened stainless steel fastening system for a secure installation without drilling into the vehicle’s painted metal. In most applications, the mudflaps mount in minutes without removing the wheels or tires, helping simplify installation and preserve the factory finish. This practical fastening system makes the kit a convenient choice for drivers who want added exterior protection without permanent vehicle modifications.
Molded from WeatherTech’s proprietary thermoplastic resin, these mudflaps are built to handle everyday driving conditions while maintaining their shape and protective function. The durable construction helps reduce the impact of kicked-up road material on the lower body panels, making the kit well suited for commuting, highway travel, work use, and changing weather conditions. The black finish complements a wide range of exterior colors and provides a straightforward, factory-style upgrade.
WeatherTech designs, engineers, and manufactures its mudflaps in the USA using American-made tooling. Part number WET110119-120119 is engineered for the listed GMC Sierra 1500 and Sierra Denali applications. WeatherTech mudflaps are covered against faulty materials and workmanship under the applicable manufacturer warranty, with exclusions for wear caused by severe abrasive conditions or chemical contamination such as gasoline or bleach.
