Return Policy

30 Day Return Period

Most products we sell are returnable. Returns will be accepted if the product is in new, uninstalled and unopened condition with all original packaging and paperwork, or if the item is defective or was damaged during shipping. Items that have been opened, installed, mounted, welded, or altered in any way are not returnable. All product returns must be pre-authorized within 30 calendar days of purchase. After 30 days all warranty or other issues must be handled with the product manufacturer. Parts received without pre-authorization will be held with no action until contact is made by customer.

Electronic Products

  • Electronic products are not returnable once opened, with the exception of items received in damaged or defective condition.
  • An RMA will not be given without a serial number. Serial numbers will be cross referenced with and must match our database. If they do not match, an RMA Number will not be issued.
  • When returned item is received, the serial number will be checked and must match the RMA for credit to be issued.
  • Electronic Tuners that are VIN locked to a vehicle are non-returnable.
  • Tuners used for attempted vehicle emissions deletes such as DPFEGR, or DEF are non-returnable.

Parts Damaged in Shipping

  • For damaged shipments, please contact us within 5 business days of receipt.
  • We will file a damage claim with the carrier. Shipping companies require the original packaging for inspection. It is your responsibility to keep all original packaging.
  • Expedited shipping is at the customer’s expense for replacement of damaged items.
  • LTL Truck Freight shipped items. Inspect all products for damage and confirm product quantity at time of receipt. If LTL shipment is damaged refuse receipt. Signature of receipt is confirmation that product is received in good condition. Please notify us immediately if you refuse LTL shipment due to damage.


Condition of Return Items & Restock Fees

Upon receipt, all returns will be inspected. If the item is damaged from installation, is missing components, manuals, original packaging, the product serial number doesn’t match the original serial number we shipped out, or for any reason the product is deemed not re-saleable due to customer actions, at our discretion, credit may be refused or a restocking fee of up to 20% may be assessed. Some items such as exhaust systems might have a re-boxing fee of up to $35 if the box is damaged to the point where it is no longer serviceable. Expedited shipping fees are non-refundable in cases of buyer’s remorse. Refunds to customers with buyer’s remorse who choose to return an item where we have paid for express shipping will have the actual express shipping fees deducted from their refund.

Returns missing components will not be credited. Parts that have been disassembled or damaged due to incorrect installation will not be credited. We are not responsible for incorrect installation by you and/or your mechanic. We are also not responsible for any expenses incurred or caused by the use of wrong or defective parts during installation. These expenses include towing, labor, repair or rental car expenses.

Non-Returnable Items

Some custom-order or special-order items are not returnable. These include (but are not limited to) all Grand Rock Exhaust stack kits and components, turbos, clutches and lift kits. If you experience issues with one of these non-returnable items, we will do everything we can to help, but all warranty work and tech support must go through the product manufacturer.
