Differential Cover Dana 44 10-Bolt

The Specialty Products Company Differential Cover for Dana 44 10-Bolt (model 4909BKKIT) is a precision-machined aluminum replacement cover engineered to seal and protect the differential assembly on Dana 44 rear axles. This aluminum differential cover combines robust construction with corrosion resistance, making it an essential upgrade for vehicles operating in harsh environments—whether navigating rocky terrain, crossing water crossings, or enduring salt-air exposure in coastal regions.

Manufactured from aluminum and finished in durable black paint, this cover delivers superior heat dissipation compared to cast iron OEM units, critical for heavy-load applications where differential temperatures spike during sustained towing or aggressive off-road driving. The included gasket and hardware ensure a leak-free seal out of the box—no improvisation required. At 3.95 pounds, the aluminum construction reduces unsprung weight while maintaining the structural rigidity needed to contain fluid under pressure and protect internal gears from external impact and contamination.

This Dana 44 differential cover is engineered for owners running heavy-duty trucks, off-road recovery rigs, and vehicles pushing their drivetrains hard. Whether you're replacing a damaged stock cover, upgrading to lighter weight, or seeking better cooling performance, the Specialty Products Company 4909BKKIT delivers OEM fitment with aftermarket durability. The aluminum construction and black powder coat finish provide corrosion resistance in demanding climates while maintaining a clean appearance under the rear axle.
