Using these fender liners is easy. First, make sure your vehicle is parked on a flat surface and the engine is off. Then, remove the old fender liners if there are any. Use the included hardware to attach the new liners to the rear of your Ford F - Series Dually. Be careful when tightening the bolts to avoid over - tightening. As for maintenance, if you choose the raw stainless finish, you can clean it with a mild soap and water solution regularly to prevent rust. For the black powder coat finish, avoid using abrasive cleaners as they may scratch the surface. Keep an eye on the liners during regular vehicle inspections to ensure they're still securely attached.
