Return Policy: All core, general and warranty returns must be approved prior to the shipment of the returning product. Please provide your order #. This will help us to process your return quickly.
You will receive ALL return instructions via email within 1 - 2 business days.
Core Returns: What is a Core?
We want to ensure that you are refunded your core charge as soon as possible, but in order to do this, we need your help to follow these guidelines.
• We require that all cores be returned within 21 days from delivery date of product requiring core charge. Failure to do so can result in forfeiture of the entire core charge return
• All cores must be returned to original warehouse that original shipment was sent from. In most cases, we do not provide return shipping labels for cores, if a return label is provided in the original shipment, use this tag. If one is not included, contact us immediately, and we can provide you with the correct address of where the core(s) must be returned to. DO NOT rely on the return address on the original label as a source for where to ship to
• If cores are shipped to the incorrect warehouse, your core money will be returned less the shipping cost for us to send the core(s) to the correct warehouse, or if you deferred the core you may be charged for the shipping amount
• Cores that have been disassembled or have missing and/or damaged major components will not receive full core credit
• Cores must be returned in the original packaging the new part was shipped in. Most manufacturers design special packaging for their products to protect them while in transit. Failure to reuse this packaging can result in damage to the core(s) which could lead to the forfeiture of your core return. Specifically regarding Bosch, they have a strict policy that core returns must be in their original packaging. If the original packaging is not used, the part number must be clearly identifiable on the part itself. If neither of these core criteria are met, no core return will be available.
• Returned cores must match the same vehicle fitment as the new part purchased. For instance, if you purchase a replacement turbo for a 2007.5-2012 Dodge Ram 6.7L Cummins, the returned core must have a fitment of that same application.
• We have the right to alter this policy (i.e. extend the terms) for any reason. If you have an outstanding circumstance, contact us
