Note regarding flares and flare kits.

Unless otherwise stated, flare and flare-kit products may offer different levels of coverage compared to factory-optioned flares. Coverage specifications, where provided, are typically measured from the original body line (base model), not from any OEM or factory flare package.

In some cases, coverage may be similar to, or not exceed, factory-optioned flares depending on vehicle sub-model, trim level, or regional specification. Certain kits may also require additional mounting hardware, drilling, or minor modification during installation. Some flares are sold as pairs (front or rear) or as full-vehicle sets, while product images may show the complete vehicle for reference only.

Where available, installation instructions are included. Please review all product images and descriptions carefully before purchase, or contact StreetFX Support if you are unsure about fitment or coverage expectations. Returns are not accepted for special-order products.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.
