At America Diesel Inc., we want your parts to reach you as quickly and safely as possible. Please review the following information about how we process and ship your order.
Order Processing Time
- In-stock products: Orders are processed and shipped within 2–3 business days after payment is confirmed. For in-stock items, next-business-day shipping may be available.
- Built-to-order / custom / swap harnesses: These items are manufactured specifically for your order. Production typically takes approximately 2 weeks, and the exact lead time is agreed upon with each customer before manufacturing begins.
- Processing times exclude weekends and U.S. holidays.
Shipping Carrier
- We ship exclusively through UPS.
- Once your order ships, UPS will send you a confirmation email with your tracking number so you can follow your package directly through UPS.
Delivery Times
- We always ship using UPS Next Day service. However, actual delivery time depends on UPS logistics and transit times, so the exact delivery date is determined by UPS, not by America Diesel.
- Delivery estimates are provided by UPS and are not guaranteed by America Diesel. We are not responsible for carrier delays caused by weather, high-volume periods, holidays, incorrect addresses, or other circumstances outside our control.
Transfer of Responsibility & Customer Responsibility — Please Read Carefully
Once America Diesel hands your package over to UPS, responsibility for the package passes to the customer and to the carrier (UPS). From that point, the handling, transit, and delivery of the package are between the customer and UPS, and America Diesel Inc. is released from all responsibility for it.
For your protection, every shipment we send is insured with UPS. This insurance covers loss or damage while the package is in transit — it does not cover theft or loss after UPS has delivered the package.
Once UPS marks your package as delivered, responsibility for the package rests fully with you, the customer. We have experienced cases where UPS leaves a package at the customer’s door and, because the customer was not watching for the delivery, the package was stolen. In these cases, America Diesel Inc. is not responsible and will not replace or refund the order.
To avoid this, we strongly recommend that once your package is in transit with UPS, you:
- Track your package and stay aware of the expected delivery date.
- Make sure someone is available to receive it, or arrange a secure delivery location.
- Consider requesting signature on delivery or a UPS Access Point pickup for high-value orders (contact us if you’d like to arrange this).
If something goes wrong, contact us anyway. While America Diesel is not obligated to replace or refund packages once they are in UPS’s possession or after delivery, we care about our customers. If you have a problem with your shipment, reach out to us at info@americadiesel.com and we will do our best to point you in the right direction, at our discretion and on a case-by-case basis. Any assistance we provide is a courtesy and does not guarantee a solution or waive the terms of this policy.
Incorrect or Incomplete Addresses
- It is the customer’s responsibility to provide a complete and correct shipping address at checkout.
- Orders returned, delayed, or lost due to an incorrect or incomplete address are the customer’s responsibility, and any re-shipping costs will be charged to the customer.
International Shipping
- We ship worldwide. If you do not see your country available at checkout, please contact us at info@americadiesel.com and we will arrange shipping and a quote for you.
- International orders may take additional time due to customs documentation and payment verification.
- All applicable duties, taxes, and customs fees are the responsibility of the customer, unless otherwise stated at checkout.
Shipping Damage
- If your product arrives with visible shipping damage, you must notify us within 24 hours of delivery, providing photographic evidence, so we can assist with a claim and replacement. (See our Changes & Refunds policy.)
