RETURN PROCESS

To return an item, please email customer service at support@gritshift.com to obtain a Return Merchandise Authorization (RMA) number. Once approved, customers are responsible for shipping the item back to GritShift using a carrier of their choice. The RMA number must be clearly included with the return shipment to ensure proper processing.

Return shipping costs are the responsibility of the customer and are non-refundable. We recommend using a trackable shipping service, as GritShift is not responsible for items lost or damaged during return transit.

INTERNATIONAL RETURNS

International shipments should be marked as a "Merchandise Return" with a carrier that does not levy brokerage fees. You are responsible for the cost of shipping the item back to us. We suggest using a carrier that provides a tracking number and a signature. The customer is responsible for any applicable brokerage or customs fees.

All shipments must be prepaid; packages shipped COD will be rejected.

REFUNDS

After receiving your return and inspecting the condition of your item, we will process your return or exchange. Please allow at least fifteen (15) business days from the receipt of your item to process your return or exchange. Refunds may take 5-10 business days to appear in your account, depending on your credit card company. All refunds will be made to your original payment method. We will notify you by email when your return has been processed.

PLEASE NOTE

• A 15% restocking fee WILL be charged for returns    

DAMAGED ITEMS

Please let us know ASAP if any items on your order arrive damaged. Please keep all original shipping containers and take pictures if possible. Damaged item claims are handled through the shipping carrier (UPS, FedEx, USPS, DHL). We will assist our customers with these claims. We only ask that customers be patient, as sometimes this process can take longer than any of us would like!

WARRANTY

Each manufacturer has its own warranty policy. GritShift will assist customers with their warranty; however, GritShift does not provide any direct warranty on items sold.

WARRANTY RETURNS

Most manufacturers offer an additional warranty period that covers merchandise defects. To determine warranty requirements for a specific item, please contact us for assistance.

Please note warranty processing may take 4-8 weeks and will be subject to the individual manufacturer's policies and discretion. Manufacturer warranties do not cover defects determined to be caused by normal wear or due to customer negligence.
