What do you need to verify fitment?
Share your vehicle details with our team and we cross reference this listing before dispatch. Anything doubtful gets a message from us rather than a shipment.

Most orders dispatch within one business day. You receive tracking by email the moment the parcel is handed to the carrier.
What if it does not fit?
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.
How do you protect it in transit?
We verify diameter and reinforcement specification on every hose order.
