To return an item, it must be in brand new condition with original packaging.

    We cannot accept a return on special ordered or custom items.

    Some items may be special order specifically for the customer’s vehicle. These items generally require a deposit or paid in full.

We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back
