Shipping Delays

We are aware there are orders outstanding. Rest assured that your order has not been missed nor forgotten. A worldwide microchip shortage and other pandemic-related challenges have slowed the supply of products in many industries, including electronics. We're sorry for this problem and are working with our manufacturers to replenish stock and fill backorders. Our advisors and support reps have no extra info on when we expect this item.
Our supply chains have been affected, distribution centers are backlogged and international shipping agencies have been severely affected by COVID19. Unfortunately, these things are completely out of our control. Once your order ships you will receive a SHIPPING CONFIRMATION email stating your order is on the way with TRACKING INFORMATION. If you have not received this email, your order is still in fulfillment que and is working its way up the list.
Due to the fluid nature of the supply chain at this time, Fat Head Cycles CAN NOT provide ETAs on bundles that have yet to ship as many times we are simply waiting on one small part or another to complete the package. We here at Fat Head Cycles appreciate you as a customer and will always do the best we can to accommodate and fulfill your requests and your need for the best Harley Davidson audio and performance products in the industry.


Thank you for your understanding.

We appreciate you,

The Fat Head Cycles Team
