Before you order
Is fitment guaranteed on this listing?
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.
Do you ship the same day?
Dispatch is normally the same or next business day, and heavy items travel on freight with a booked delivery window.
Can I return this part?
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.
Is the part inspected before dispatch?
We verify diameter and reinforcement specification on every hose order.
