            MAP Limited Lifetime Warranty

            1.) All MAPerformance in-house fabricated parts include a Limited Lifetime Warranty for the Original Purchaser. This warranty only applies to the original purchaser and is non-transferrable. If the product fails it would need to be determined by MAPerformance that it is due to manufacturing defects in materials or workmanship.

            2.) This does not cover normal wear and tear. Improper use, modification, or abuse voids this warranty. MAPerformance will not be held responsible for additional costs due to the failure of a product (cost of sale, towing, labor, etc.). Warranty claims must be submitted to MAPerformance for review.

            3.) You must create a support ticket to acquire your return authorization number prior to returning the product.

            4.) Warranty claims will not be honored if the product was not purchased through an approved dealer.

            For warranty evaluation please create a support ticket via this form here.
