Our company combines hard-core drag racers and auto enthusiasts with tech-savvy engineers and developers — all car lovers — to create a webstore that gives you an unmatched shopping experience — and we deliver it fast. Very fast. Unlike traditional brick-and-mortar retail outlets, our inventory isn’t limited to what we can pack into a storefront or what a counter clerk may be able to find. While they can only offer you hundreds of items, you’re just a few clicks away from millions of parts when you shop PartsHawk — all in stock and ready to ship. And since we don’t own any of those expensive stores, we can offer our parts for less, and that saves you money on every part, every day. A better shopping experience, for every product for every car, whenever you order. |

| What if my order shows shipped but the package is not moving?
At times there is a delay in the carrier’s tracking for updates. Please allow up to 24 hours for your tracking to update. If you still do not see any movement, please contact our Customer Service Department and we will be happy to assist. |
What if I am not available when the carrier tries to deliver?
If there is no response when the package arrives, the driver may leave the package nearest to the street or make a second delivery attempt on the next business day. Please check your tracking info as it will let you know the next steps for delivery attempt. |
How can I get a copy of my receipt or invoice?
|
|
What if the tracking number is not working after 24 hours? Depending on the size of your item, it could be shipped with a truck carrier and will require you to be present at time of delivery. Please feel free to reach out to us and we will provide additional details. |
I have special delivery instructions (i.e. Leave by back door, leave with neighbor, place in the planter on the left of my garage, etc.) We recommend leaving a note for the carrier on the door nearest to the street as we do not have a way to communicate those requests for you. |
Why did my item ship from a different location?
Many parts are stocked in more than one warehouse location. As a result your order may ship from a location other than the location shown in the listing. In most cases the shipping location will be closer to delivery address as we always try to ship from the closest warehouse to minimize transit times. In some circumstances intraday sales and other inventory changes may result in your item being shipped from a location further from your delivery address. |
|
Do I have to be there to sign for my package? If your order is over $250 there is a possibility it was shipped with a signature required option. The easiest way to check is to locate the tracking number for your order and open on the carrier’s website. There is no additional cost to you for this service. |
Can I pickup my part/order from your warehouse? Sorry, we do not offer the pickup in warehouse option as our warehouses do not have public access |
How do I know if this part will fit my vehicle? Check the vehicle compatibility guide above or just reach out to us. Updated 10.19.2023 |
