Pinion Seal Dana 30/44/ 50

The RATECH Pinion Seal Dana 30/44/50 (SKU: RAT6116) is an essential component designed to prevent gear oil leakage at the pinion yoke interface on Dana axle housings. This seal is crucial for maintaining the integrity of the drivetrain in trucks, SUVs, and off-road vehicles equipped with Dana 30, Dana 44, or Dana 50 rear differentials. Whether you're rebuilding a differential after high-mileage service or addressing an active leak, this OEM-style replacement seal is a reliable solution.

Constructed from a durable rubber and steel composite, the pinion seal features elastomeric sealing lips combined with a steel backing ring. This dual-material design ensures reliable contact pressure against the pinion shaft while providing structural rigidity and corrosion resistance in harsh environments. The rubber maintains a tight grip even with slight variations in shaft runout, ensuring effective sealing.

Owners of Dana 30-equipped Jeeps, Dana 44-equipped full-size trucks, and Dana 50 heavy-duty vehicles will benefit most from this seal, especially those experiencing weeping or active gear oil seepage at the pinion yoke. Installation requires basic differential knowledge, making it accessible for DIY enthusiasts and professional mechanics alike.
