Aero Function diffusers are aftermarket aerodynamic accessories designed specifically for off-road and show use. Aero Function disclaims any responsibility for damage or injury resulting from their use. These diffusers are not intended for public road use and are not ‘direct bolt-on’ parts. They often require extensive preparation, such as sanding, fitting, or custom bodywork. It’s important to note that improper handling or installation can lead to common issues, such as potential warping, cracking, or fitment challenges.
Aero Function diffusers typically fit below the rear bumper, and in many cases, the bumper may need to be modified to accommodate the diffuser. Many diffusers are designed to fit specific bumpers or trims, so careful attention should be paid to design and compatibility during selection and installation.
Installation of Aero Function diffusers usually requires separate mounting hardware, which is not included in the package. This hardware may consist of L-brackets, bolts, screws, washers, and other fasteners. L-brackets are commonly used to attach the diffuser securely to the vehicle's chassis or bumper, while bolts and screws ensure a tight fit. Additional supports or reinforcements might be necessary, depending on the design and specific fitment of the diffuser. Since this hardware is not included, installers will need to source the appropriate materials separately to ensure compatibility with both the diffuser and the vehicle.
For optimal results, Aero Function recommends professional installation by a custom shop experienced with fiberglass components and aftermarket accessories. Traditional auto repair shops may lack the expertise needed for the nuances of proper fiberglass fitment and hardware requirements.
