Shipping Delays

We are aware there are orders outstanding. Rest assured that your order has not been missed nor forgotten. Things here at Fat Head Cycles have changed drastically over the past few months and our small operation has had to adjust and adapt to maintain the accuracy and quality of our products. Our supply chains have been affected, distribution centers are backlogged and national shipping agencies have been severely affected by the COVID19 issue and inclement weather in our area. Unfortunately, these things are completely out of our control.

The majority of orders containing Sony and Rockford products take between 21-28 BUSINESS days to custom assemble, ship and arrive at your doorstep. 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 CANNOT 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
