Our Lifetime Replacement Guarantee (LRG) is a program specific to the products purchased from FCP Euro. We support our LRG program in-house, and it does not have any cross-over into a manufacturer's warranty.
A manufacturer's warranty would be specific to the brand that produced the product in question. Any warranty would be supported through the brand that produced the product, and would not cross over with the FCP Euro LRG program.
If for some reason, you wish to claim a manufacturer's warranty on a part bought from us, you must contact the manufacturer directly. Most manufacturers will require some type of documentation of purchase and failure from a reputable shop. Your purchase history is available within your FCP Euro Account or through your order confirmation emails in your email inbox.
