DEF Racing Return Policy

Effective for purchases from DEF-Racing.com.

Return window

You have 14 days from the delivery date to start a return. After that, the order is final sale unless the item is defective or we shipped the wrong product.

Starting a return means contacting us and receiving approval before you ship anything back. Do not send product without authorization.

How to start a return

Email Info@DEF-Racing.com or call (704) 534-4406 with:

  • Order number
  • Item(s) and quantity
  • Reason for return
  • Photos if the item is damaged, incorrect, or you believe it is defective

If approved, we will issue a Return Authorization (RMA) and shipping instructions. Packages without an RMA may be refused or delayed.

Condition requirements

Returned product must be:

  • Unused and in new, resaleable condition
  • Never installed, assembled, or test-fitted in a way that leaves marks, wear, oil, thread locker, or tool marks
  • In the original manufacturer packaging with all hardware, manuals, labels, bags, and accessories

If it does not meet those conditions, we can refuse the return or reduce the refund.

Restocking fee

Approved returns are subject to a 20% restocking fee.

Original outbound shipping is not refunded. You pay return shipping and any related duties or brokerage. We recommend insured shipping; we are not responsible for returns lost in transit.

Electronics — no returns

Electronics are non-refundable. This includes (but is not limited to) ECUs, tuners, modules, ignition parts, sensors, and any item we have programmed, mapped, or customized.

Opened electronics cannot be returned. Because of programming, licensing, and the nature of race electronics, we cannot accept electronics back for refund or exchange except where required by law for a verified defect covered by the manufacturer.

Items that cannot be returned

  • Electronics (opened or unopened, except a verified DOA/defect handled under warranty)
  • Custom, special-order, mapped, or made-to-order items
  • Labor, machine work, cylinder head work, engine builds, dyno time, coatings, and other services
  • Installed, used, modified, or damaged parts
  • Items missing original packaging or accessories
  • Clearance / final-sale items marked as such

Defective or incorrect items

If we shipped the wrong part, or the item is defective on arrival, contact us within the 14-day window with photos and the order number. We will arrange a replacement or refund. Do not install a suspected defective part.

Manufacturer warranties (when they apply) are handled by the manufacturer or through us as dealer support. Our return policy does not replace a manufacturer warranty.

Fitment

Confirm year, model, and application before you order. Wrong fitment from customer error is not a free return. It is treated as a standard return if the item otherwise qualifies (new, uninstalled, original packaging) and is subject to the 20% restocking fee.

After we receive the return

We inspect the item. If it qualifies, we process a refund to the original payment method, minus the 20% restocking fee and any non-refundable shipping. Timing is typically several business days after inspection, plus your bank’s processing time.

Store credit may be offered instead of a refund in some cases.

International orders

The same rules apply. The customer is responsible for return shipping, customs, and duties. We do not refund original international shipping or import charges.
