Ford Performance offers a heavy-duty differential cover for Super Duty 14-bolt rear axles designed for 2011–2022 single-rear-wheel M275 (10.8 in.) applications. The nodular iron cover is powder-coated for corrosion resistance, includes hardware and gasket, and features a magnetic drain plug and a Ford Performance logo. Engineered for tougher service, it replaces the factory cover with a durable, service-friendly design.
