The Rough Country SF1 is a set of four bolt-on fender flares for the 2018–2020 Ford F-150 in 2WD or 4WD. They add tire coverage for oversized wheels and tires, and an integrated rear mud catcher cuts down on tire sling along the body. The Tri-Blend ABS is UV protected so it can stay unpainted, and it is paintable for a color match. Compared with rivet-style flares, the SF1 keeps a cleaner body-line look and installs without drilling.

Owners of the SF1 flares generally report a clean fit and a straightforward no-drill install. Most like the added tire coverage and the mud catcher. Some mention the unpainted finish and plastic feel as drawbacks.
These SF1 fender flares are made for the 2018-2020 Ford F-150, 2WD and 4WD. They follow the truck's body lines and add tire coverage for an oversized wheel and tire package. An integrated rear "mud catcher" helps reduce tire sling down the side of the truck.
The flares are built from Tri-Blend ABS material and are UV protected to prevent fading. They add protection from rocks, mud and other road debris. They can be installed uncoated or painted to match the truck.
Installation requires no drilling, and all necessary hardware is included. The flares can be removed to return the truck to stock.
