Installation Requirements

We want all consumers to know that there will always be some minor sanding, shaving, cutting, and/or filling prior to installing Extreme Dimensions parts. Also, the black primer finish must be sanded and other prep work will be required prior to painting.

"Our customer guarantee is that you can return your item within 30 days of receipt for any reason as long as it is returned in the original packaging and you pay for all shipping; original shipping fees are non-refundable.

It is recommended that the part be installed by a professional body shop that has experience working with aftermarket fiberglass and urethane body kits including but not limited to sanding, shaving, cutting and filling.

While larger rear spoilers look great on a vehicle and improve airflow, they can often be so close to the ground that backing out of angled driveways causes their early demise. The Rear Diffuser by Aero Function lets you add the aggressive looks and enjoy the style of an air dam or lowered spoiler without the reduction in ground clearance that comes with them. This add-on piece mounts directly to the lower section of your rear bumper cover easily, and all necessary instructions are included. You'll also enjoy the benefits of improved aerodynamics with contoured wind strakes that reduce drag on the back of your vehicle. Should you wish to match your vehicle's body color, we recommend priming and 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.
