Shipping & Returns

Free UPS Ground Shipping to the Continetial US on orders over $100 excluding freight items.  Some items require 1-3 days processing time. You may return most new, unopened, seal-unbroken items purchased from Custom Diesel within 14 days of delivery for a refund less shipping and 15% restocking fee. Opened/installed items may be non-returnable. Please note: We reserve the right to adjust or refuse the refund depending on resale-ability. All returns will be subject to inspection (we are not responsible for products being returned to us that are damaged mid-shipment). Please try to include all original packaging, manuals, pieces and parts in order to avoid being penalized. Used, damaged or altered items are not refundable. Some items, including Special Orders, truck freight shipments and some non-stocked items are not returnable under any circumstances. Although we offer "free" shipping to you, it is not free to us and therefore may be deducted from refunds when appropriate. Custom Diesel is not responsible for items returned without obtaining a Return Authorization. Items returned without first obtaining an RMA will not receive credit. Have a return? 1. Call in to get a return material authorization number (RMA) 2. Prepare your package in original packaging with all parts, pieces, and paperwork 3. Ship it (insure it appropriately, we are not responsible until we get it) 4. Track your package to the warehouse (notify us with a tracking number so we can track it too) Did we make a mistake? Replacement Policy Replaced items that are not shipped back to us in a timely manner (7 days) or are damaged/used/missing pieces or are not the original part shipped to you are your financial responsibility and charges will be made accordingly. If we sent you additional items in good faith, you in turn agree to return the items to us or be charged for them. If you are charged, refunds can only be made once the original item is received, inspected, and determined to be in good condition, less the 5% credit card processing fee that we had to pay. Want to cancel an order? Cancellation requests on items that have already shipped will be assessed the cost of all freight, including the return freight to the warehouse. Any circumstances outside of our control (carrier delays, incorrect address, inclement weather) are not cause for cancellation and any such returns will be subject to all normal return fees. What if there is an error or problem with my order? Do we make mistakes? Yes. We will replace the item if we made an error, but you are responsible to return the incorrect item within 7 days or we will charge you.
