Fenders are the add-on body cladding automakers often use to simulate the modified, wider fenders manufacturers use on racetrack prepared versions of their vehicles. On the showroom floor, they distinguish performance models from base versions - indicating a vehicle is built with higher levels of power and speed. While fender flares add a wider stance to give a vehicle a more broad-shouldered, muscular stance, they serve aerodynamic functions that become more important as higher velocities are reached. Fender flares are also contoured to manage airflow, reduce wind noise, and channel rain so it stays low on a vehicle's body away from glass areas where visibility can be blocked. If your vehicle was not so equipped from the factory, we let you add their looks and benefits with the multi-piece Fender Flare kit from Aero Function. All pieces in the kit are delivered to you with primer layers already applied by Aero Function, and should you wish to match your vehicle's body color we recommend painting before installation.

Advanced computer aided design and high-tech manufacturing processes ensure all Aero Function components fit evenly against every panel and contour of your specific make and model. Once parts have been prepped and installed on your vehicle, they achieve a look that matches the quality of original equipment without the gaps, uneven edges, and poor visual continuity that plague parts from inferior competitors. Depending on vehicle application, components may be produced from carbon fiber plastics, fiberglass composites, or polyurethane polymers. Aero Function is well-respected throughout the industry for the development of each of these lightweight composite materials which feature extremely high levels of strength, rigidity, and superior impact absorption. Even under the harshest climates and conditions, Aero Function parts have proven their ability to maintain integrity without warping or cracking for long periods of time. Add-on aero pieces can be installed using any method of your choice such as double-sided tape or weather stripping adhesive, and Aero Function backs what they build with a 3-year warranty against defects.
