Handling Time
At All Pro Truck Parts we do our best to ship all orders the same day for orders placed before 12:00 PM Central Standard Time. Same-day shipment is never guaranteed. For standard UPS shipping, you will typically receive your package in 1 - 5 business days. Shipping times are never guaranteed and All Pro Truck Parts is not responsible for lost or delayed shipments by the carrier. Carrier times vary by distance from shipment origin and may change without prior notice. Shipping price is calculated from package dimensions and weight. Calculated rates for orders will be available at checkout. Orders placed after 12:00 PM CST on Fridays will not be fulfilled until the following business day, Monday morning barring a holiday.

The cutoff time for UPS Next Day Air is 12:00 PM CST. Orders for Next Day Air placed after 12:00 PM CST will ship the following business day.

Incorrect Shipping Prices
All Pro Truck Parts reserves the right to cancel any order in the event shipping rates are calculated incorrectly at checkout. We will notify you at your provided contact information to give you the option to pay the correct amount, or allow you to cancel the order for a full refund.

Shipping Destinations
All Pro Truck Parts ships within the United States only. We do not currently offer international shipping.

Damaged Shipments
All Pro Truck Parts is not responsible for damage that occurs in transit - responsibility for damaged shipments lies with the carrier. However, we are glad to assist by filing a claim with the carrier on your behalf.

If your package arrives damaged, please do the following:

1. Refuse delivery if the package is visibly damaged at the time of arrival, and note the damage with the driver.
2. If the damage is discovered after delivery, photograph the outer packaging BEFORE opening the box, then photograph the contents showing the damage.
3. Keep all original packaging, including boxes, packing materials, and labels. Carriers may require an inspection before approving a claim.
4. Notify us within 48 hours of delivery by submitting a damaged shipment report at help.allprotruckparts.com/damaged-shipment.

Once a claim has been filed, resolution is determined by the carrier. Refunds and replacements for damaged shipments will only be issued after the carrier approves the claim. Failure to report damage within 48 hours, discarding the original packaging, or opening a visibly damaged package without photographing it first may result in the carrier denying the claim, in which case we are unable to refund or replace the item.

To be eligible for a return, your item must be unused and in the same condition that you received it. It must also be in the original packaging.

Restocking fee and return shipping
Returns of new, unopened items are subject to a 20% restocking fee, which is deducted from your refund. You pay the shipping to send the item back, and shipping costs are not refunded.

Used items (if applicable)
Items marked as USED at the time of sale will be accepted for return up to 30 days from the date of sale.

Defective parts (warranty)
A part that fails is handled through the manufacturer's warranty process, not as a return. The manufacturer reviews the claim and decides whether the part is defective for the application it was purchased for. If you need a part right away, you will need to purchase a replacement rather than wait on the warranty review. Start a warranty claim at help.allprotruckparts.com.

Only regular priced items may be refunded. Sale items cannot be refunded.

Special order items (if applicable)
Special order items may be eligible for a refund. The decision to accept a special order item for refund is left solely to the All Pro Truck Parts management team.
