Are you swapping oil pump gears on your 2015+ Mustang GT? If so then you'll want to get a new OEM replacement water pump o-ring as the factory one swells up and once removed from the factory water pump can't be reused. We recommend this o-ring as well as a new crank bolt whenever doing an oil pump gear swap.
Please Note: We do our best to provide accurate shipping quotes, but due to some of the packaging provided by Ford being larger or heavier than expected, at times, additional shipping may be required.
