Contoured specifically for each application and molded from a proprietary thermoplastic resin, the WeatherTech No-Drill MudFlap will offer undeniable vehicle protection.Unparalleled ProtectionThe WeatherTech MudFlap provides protection for your vehicles most vulnerable rust area. No-Drill MudFlaps protect the fender and rocker panel from stone chips, slush, dirt and debris. QualityWeatherTech MudFlaps are proudly designed, engineered and manufactured with American made tooling in the USA.Warranty WeatherTech MudFlaps are guaranteed against faulty materials and workmanship for a period of three years from the date of purchase. Exclusions to this warranty are wear due to severe abrasive conditions and chemical contamination, such as spilled gasoline, bleach, etc.

WeatherTech designs and manufactures custom-fit vehicle protection products, most recognisably the laser-measured FloorLiner. The range extends to all-weather floor mats, cargo and trunk liners, mud flaps, bed liners, sun shades and interior accessories. More than 95 percent of production happens in the company's own Illinois factories, with parts engineered vehicle by vehicle rather than trimmed to fit.
WeatherTech was founded in 1989 by David MacNeil, working out of his home in Clarendon Hills, Illinois. He was dissatisfied with the automotive floor mats then sold in the United States, which neither contained dirt and water well nor cleaned up easily, so the company began by importing higher-grade mats from England. Convinced a better product could be built domestically, MacNeil moved to U.S. contract manufacturing in the mid-1990s and by 2007 had shifted the entire line into company-owned facilities in the Chicago suburbs.
The brand is best known for the FloorLiner, a floor mat digitally measured to the exact contours of a specific vehicle's footwell, with raised edges that channel water, mud and salt away from the carpet. The same custom-fit approach carries through the rest of the catalog. Cargo and trunk liners protect the load area of SUVs and wagons, bed liners guard pickup beds against cargo damage, and window deflectors, sun shades and seat protection round out interior coverage.
Outside the cabin, WeatherTech produces mud flaps that mount without drilling on most applications, along with complete mud flap kits that shield rocker panels and paint from stone chips and road spray. The company also makes home and pet products using the same materials and tooling.
Scale is part of the story. WeatherTech maintains more than ten thousand floor mat part numbers, has developed thousands of product molds in-house, employs well over a thousand people in the United States, and sells into seventy-nine countries. Products are designed and engineered at a development center in Downers Grove and produced in Bolingbrook, Illinois. For owners of work trucks, family vehicles and anything driven through winter salt or job-site mud, the appeal is straightforward: parts that fit one vehicle properly, made from materials that stay flexible in cold and wipe clean.
