101 Diesel offers free Economy Shipping on all products within the lower 48 states. Economy Shipping takes 5-7 business days to reach customers. In addition to shipping direct from our main warehouse, we also ship from 5 warehouses scattered throughout the US and have the ability to ship direct from many of the manufacturers that we carry. If possible we will always ship your products from the closest available warehouse.

All Free Shipping offers ONLY apply to the lower 48 states. In some cases we will extend the offer to Alaska, Hawaii and Canada but this is on a case by case basis and applies to call in orders only. We cannot offer free shipping to international orders. We are working on a separate international checkout that will assist with all Canadian and overseas orders.


We do everything in our power to get your order processed and shipped in the shortest time frame possible. Most orders will ship out either same day or within 1-2 business days, some exceptions may include back ordered items or items shipped directly from the manufacturer. Please allow three (3) to ten (10) business days for delivery of in-stock items. Items ordered together are not necessarily shipped together. We will notify you if any item cannot be shipped within 30 days. If you would like to check inventory or estimated ship date please contact us via phone or e-mail.


  • Economy Shipping- This option does not include a standard tracking number, only delivery confirmation is available. This is the slowest method of shipping and often takes 6-10 business days for delivery. We reserve the right to automatically upgrade this shipping option to UPS Ground if we see fit.
  • UPS Ground - This is our preferred method of shipping. A tracking number will be available usually within 1 day of shipping.

  • UPS Next Day Air - Next day air transport. The cut off for next day air is 1:00pm PST in most cases. Also, it is not available for all parts. If we cannot ship it Next Day Air, but the site said it could, we will contact the buyer and let them know. A tracking number will be available usually within 1 day of shipping.

We will only ship to the 48 U.S. states. For customers in Alaska, Hawaii and Canada please consider calling in your order so we can arrange suitable shipping.

Separate Shipping and Billing Addresses

If you choose to use 2 different addresses for your order and you have not purchased parts from us before, it might cause a delay in shipping due to the verification process. If the delay in shipping concerns you, please call in your order.

Signature Requirement

For your protection and ours, we ship almost all packages with a signature required for delivery. If you specifically want us NOT to require a signature for delivery, please make a notation in the "Order Comments" field you see on the order form.

PLEASE NOTE: Any insurance claims for damaged items and/or stolen goods from your doorstep that are NOT honored by the shipping carrier because you requested a signature not be required for delivery is NOT our responsibility. We will not cover the cost!

*Some items shipped directly from the manufacturer or alternative supplier may arrive via Fedex or USPS.

Although we operate out of Monroe Township, NJ, we have 5 shipping warehouses all across the country. We do this because it usually speeds up the shipping to our customers. With multiple warehouses, most of our parts will reach the customer faster than if we shipped everything out of Monroe Township, NJ. If you want to know which area of the country a part will be shipped out of, just give us a call. Also because we have multiple warehouses, we sometimes will ship a part a longer distance because the warehouse nearer is out of stock.


We currently are unable to ship to military bases through our online checkout because our default shipping supplier, UPS, does not offer any shipping options for Army Post Offices or Fleet Post Offices. If you would like us to ship your order to an APO or FPO, then please give us a call at and we can manually process your order over the phone and ensure your order is shipped via USPS to avoid any potential issues.
