Returns and Refunds Policy

Return windows are set per product and shown on the product page, in your cart, and at checkout. The return period begins on the confirmed delivery date.

Each product carries a return record that includes:

• Returnable or nonreturnable status
• Return window
• Restocking fee
• Return shipping responsibility
• Required condition
• Supplier instructions
• Original shipping refund rule
• Product-specific exclusions

Do not return a product without an approved Return Merchandise Authorization.

Request an RMA through support. We provide the return address and supplier instructions with the authorization.

Unless the product page expressly states otherwise, these are nonreturnable:

• Installed parts
• Modified parts
• Used parts
• Electrical parts, opened or unopened
• Tuning devices
• Software and downloadable tunes
• Special-order parts
• Made-to-order parts
• Opened gasket kits
• Opened seal kits
• Fluids
• Chemicals
• Clearance products
• Custom configurations

Freight products are not automatically nonreturnable. Freight return eligibility is product-specific.

Incorrect, damaged, defective, or mis-shipped products are handled under the Incorrect, Missing or Damaged Items process or the applicable warranty process rather than being rejected under these exclusions.

You pay return shipping when:

• You changed your mind
• You selected the wrong product
• You selected the wrong configuration
• You selected the wrong vehicle
• The return is otherwise voluntary

FullSpecDiesel coordinates return shipping at no cost to you when:

• The supplier shipped the wrong product
• The product arrived damaged and the claim is approved
• FullSpecDiesel displayed materially incorrect product information
• FullSpecDiesel made the order-entry error

Warranty return shipping follows the applicable warrantor's terms.

Restocking fees are supplier-specific. There is no single global restocking fee.

The applicable fee is shown on the product page when available, and in your cart, at checkout, in the return request, and on the return authorization.

We do not deduct a fee that was not disclosed before purchase, except where legally required circumstances apply.

A refund is issued after the returned product is received, inspected, and the return is approved.

Approved refunds are processed within 10 business days after inspection and approval, and are issued to the original payment method.

We do not offer store credit or direct exchanges at launch. Return the original product and place a new order for the replacement product.

Original shipping charges are not refunded for voluntary returns. Original shipping may be refunded when FullSpecDiesel made the error, the supplier shipped the wrong product, the product arrived damaged and the approved remedy includes shipping, or applicable law requires it.
