Dana Spicer 10023539 Ford 9.75 Nodular Iron Differential Cover
The Dana Spicer 10023539 Nodular Iron Differential Cover is a heavy-duty performance differential cover designed for Ford 9.75-inch rear axle assemblies. Manufactured from high-strength nodular iron, this genuine Spicer cover provides increased rigidity and protection compared with a conventional stamped-steel differential cover, helping safeguard the differential gears, bearings, and lubricant in demanding work, towing, performance, and off-road applications.
The 10023539 features a 12-bolt mounting configuration and durable natural gray finish. Dana supplies the cover with the key components needed for installation, including mounting bolts, gasket, drain plug, and filler plug, making it a complete replacement or upgrade solution for compatible Ford 9.75 axles.
Spicer nodular iron performance covers are engineered with reinforced ribbing to help protect internal differential components from impacts and off-road hazards. Their rigid construction also helps reinforce the axle housing, while the raised fill location supports increased lubricant capacity in applications operating at higher pinion angles.
