Shipping & Returns

Q: Shipping

Typically, items priced over $50 ship UPS or FedEx ground for free to the Lower 48 States.* Overweight, large or special orders may incur additional freight charges.

Most products ship Signature Required, requiring an adult signature upon delivery. If a shipment is refused or undeliverable, the customer is responsible for any additional handling charges and restocking fees. We are not responsible for addresses deemed undeliverable or packages redirected for pick-up at an alternate location by the carrier.

As the responsible party, UPS and FedEx maintain the option to require a signature at the time of delivery, regardless of the recipient’s requests. Pure Addiction Diesel Performance is not liable for damaged or lost orders.

International Shipping:

International shipments are those made outside the lower 48 United States. International shipments are subject to shipping quotes and approval from the customer of the shipping amount before we will ship the product. We reserve the right to cancel an order and issue a full refund for shipments not covered in our normally serviced area. Customers are responsible for all duties, taxes and fees for International shipments. Any uncollected fees will be charged to the customer and cannot be refunded. As our customer, you agree to this policy by purchasing with Pure Addiction Diesel Performance.
