What Can I Return?

If you are not completely satisfied with your purchase, we will be happy to accept a return for a refund or exchange on products in new/unused condition within 7 days of delivery.

Items must be in new condition and in the original packaging (please do not assemble, install, or modify the product in any way). In the event of fitment, flaw or defect pictures may be necessary to complete your request.

The following three exceptions for items that cannot be returned, we could discuss the solution together accordingly.

1. Shipping Damage

JC Sportline packs all products carefully to prevent damage during shipping. However, damage may still occur occasionally. The buyer must inspect the packaging and the products carefully upon receiving them, then accept the shipment and notate any damages and irregularities, such as crushed, torn, punctured, or broken parts on both the packaging and the product, on the freight bill or receipt at the driver's presence. The buyer must retain all cartons, packing materials, and damaged products for the carrier's damage inspector to inspect. Do not refuse a shipment or return it without approval, because the buyer's right to make a damage claim may be denied. A signed receipt without any notation indemnified the carrier as well as JC Sportline from any further damage claims. The discovery of damages after a clear delivery becomes the responsibility of the customer.

All damages must be notified to the carrier and the seller within 24 hours. 

2. Defective Products

All products require professional installation. Minor adjustments might be necessary. These are normal body work and installation steps. Therefore it is NOT considered to be defective. In addition, most carbon fiber products are hand-crafted, and no two items will be identical. Small imperfections such as wavy weaves, small bubbles, and clear coat blemishes are inevitable. Pictures are required to demonstrate true defects on products prior to return.

3. Installation

All products require professional installation. The buyer understands that some products may require modifications for correct fitment. Minor adjustments may be necessary as part of the normal installation process. All carbon fiber products will not sustain heavy force or weight, for they could be cracked by such force or weight. JC Sportline has made an effort to produce all its aftermarket products to fit the original factory vehicles as closely as possible. However, some occasional prepping may be necessary for an ideal fit. The buyer needs to perform these steps to his/her satisfaction before installation. If the buyer wishes to paint the products, he or she must pre-fit the parts to the vehicle before painting to ensure proper fit. There are absolutely no returns on painted products.
