About this part
Ford F-150 Fender Flares, 1-Inch Coverage (2018–2020), fitment-checked
A 1-inch-coverage flare set at a 5-inch height for the 2018–2020 Ford F-150 in rear-drive or 4WD. It mounts on factory locations, so no drilling is involved, and it comes back off cleanly later. Raptor models do not fit, and neither do trucks equipped with factory running boards. Backed by a 3 Year Limited Warranty.
Fitment spans the full 2018–2020 F-150 trim walk — XL, XLT, Lariat, King Ranch, Platinum, Limited — along with Police Responder and SSV. Raptor is not included, and factory running boards rule a truck out. The flare adds a modest 1 inch of width per side at a 5-inch height, which suits a stock-height truck on slightly wider tires more than a lifted build. Tri-blend ABS shrugs off thrown gravel, the finish resists UV fade, and the surface is ready for color-code paint. A downloadable installation guide is available.
