Steel, fiberglass, and carbon fiber Mercury Mountaineer fenders can give your vehicle a fresh look if your originals are damaged or otherwise unsightly. Carbon fiber Mercury Mountaineer fenders, as well as many fiberglass versions, can be much lighter than factory Mercury Mountaineer fenders, which is important if your ride is built for speed, and with the extra room that some of them provide you can run larger wheels and tires without worrying about clearance.

Whether you're looking for metal, fiberglass, or even carbon fiber Mercury Mountaineer fenders, you will need to have them painted to match the rest of your paint. Steel Mercury Mountaineer fenders are generally exact replicas of the originals, while fiberglass and carbon fiber Mercury Mountaineer fenders are often flared to allow for wider wheels and tires, and may have vents behind the wheel openings. These vents, although mostly for aesthetic purposes, do provide some level of cooling for your Mercury Mountaineer front brakes as well. Installing Mercury Mountaineer fenders is relatively easy as long as you're careful to not scratch your paint.
