Delivery Inspection Procedure

**Oversized Freight Delivery Requires Inspection Upon Delivery (Tractor Trailer Shipments Only)

**It is extremely important to follow these instructions exactly to ensure that your shipment will be covered by the damage insurance.

When the shipment arrives, please be sure to thoroughly inspect the box and its contents for any major damage to the parts. You must unpack the order and remove each item from the box to check for concealed damage. If you do find damage to any of the items, please physically write "Damaged" on the delivery bill. Do not write anything else other than "damaged" on the delivery bill as it can affect the outcome of a claim decision by the shipping company. You will then accept the shipment as is, and notify us immediately. We will ask for digital pictures to verify that damage has occurred as it will be needed for processing the claim. In the instance major damage has occurred, we will file a damage claim with the shipper and ship you new parts as soon as they are available.

**Please note that if a product is damaged in transit and it was not inspected at delivery and not noted so on the delivery bill, we will be unable to assist beyond that point. Once the customer signs the bill of laden the shipping company will not allow us to submit a claim on your behalf.

**For orders shipped to a body shop it is your responsibility to contact them prior to delivery to ensure they inspect it before signing for it. If your body shop signs for the package without inspecting its contents for concealed damage we will not be able to file a claim for you with the shipping company.

**Do not discard any of the packaging or plastic wrap when a damage shipment occurs. We will need images of the box as well as the internal packing. We will also need image of the part # label that may appear on the part or bagging if applicable.

I agree that I will inspect the item at delivery and fully understand that if I do not inspect this item at delivery and unbox it at a later time to find concealed damage that I waive all rights to file a damage claim on the delivery insurance. I also fully understand that a damaged item cannot be returned for refund or store credit under any circumstances.
