Keep your order confirmation, because warranty claims are processed against the original purchase record.\u003c\/p\u003e\n\u003cstrong\u003eWill you confirm fitment before it ships?\u003c\/strong\u003e\n\u003cp\u003eSend us the year, make, model, engine and drivetrain of the vehicle along with part number 9-21070 and we will check the application against the manufacturer data before the order goes out.\u003c\/p\u003e\n\u003cstrong\u003eHow quickly does this ship?\u003c\/strong\u003e\n\u003cp\u003eOrders normally leave the warehouse within one to three business days once the order is verified.
