Frequently asked questions
What do you need to verify fitment?
Trim level, engine option and drive type decide most fitment questions. Send those three details or the VIN and we will check them for you.
What are the shipping times?
Orders placed before early afternoon on a business day usually leave our USA warehouse the same day, and tracking is emailed when the label is created.
What is the return policy?
If the part does not fit, message our support desk with the order number and we will arrange an exchange or refund. Keep the packaging until the test fit is done.
What happens before my order ships?
Lines and fittings are checked for pressure rating, inner diameter and ply count before shipping.
