Built specifically for the 2021-2023 F-150 with a 5.5-foot bed, the Duraflex Maxxen 4-inch bulge rear bedsides replace the factory quarter panels with aggressive flared bodywork that visually widens the truck's stance and accommodates larger tire and wheel combinations.
Four inches of additional width per side. The Maxxen bulge profile extends the rear bedside contour outward, creating clearance for wider rubber while maintaining a clean, factory-finished appearance rather than bolt-over fender flares.
Bed-specific fitment. These panels are dimensioned for the 5.5-foot short bed F-150, so the bodylines, stake pockets, and tailgate transition align correctly without modification to adjacent panels.
Duraflex composite construction. Duraflex body components are molded from a fiberglass-reinforced composite that accepts body filler and paint like steel but resists cracking and denting from road debris and minor impacts.
