Q: When will my order ship?

Orders received by 2PM Pacific time (business days M-F, holidays excluded) typically are processed the same day received; however, manufacturing times, back orders, and other factors may delay processing and shipping. Shipping times vary depending on your location and selected shipping options. Back ordered, build to order, specialty items and other parts may require additional time for processing and fulfillment. Shipping delays can occur when the wrong address, zip code or other errors are submitted for the shipping address. If the shipping company cannot deliver the package we will contact you via phone or e-mail. For UPS shipments you can track the progress of your order by entering the tracking number on our website here: Sinister Diesel UPS Tracking.

Shipping delivery times including next day and expedited shipping are based on business days (Monday-Friday). While most orders placed after 3pm PST Friday, on the weekend or on holidays process and ship the next business day, some orders may be delayed and ship later due to manufacturing times, back orders, and other factors. Confirmations and tracking numbers are sent after orders have been processed and shipped.
