Spicer Upgraded Front Inner Axle Tube Oil Seal Kit for Ford Super Duty (Dana 50 / Dana 60)

Keep your front differential gear oil isolated and protect your internal housing from external debris with this genuine, Upgraded Spicer Front Inner Axle Tube Seal Kit. Specially engineered for Ford F-250 and F-350 Super Duty trucks equipped with Dana 50 or Dana 60 front axles, this service kit includes the premium, redesigned internal seals required to restore clean, leak-free operation.

The internal tube seals are pressed deep inside the center section of the housing on either side of the differential carrier. Their vital job is to contain the gear oil within the center pumpkin, preventing fluid from traveling down the long axle tubes or leaking out at the knuckles. Over time, high mileage, axle shaft vibration, or rough installation can compromise standard factory seals, leading to low differential fluid levels and messy undercarriage pooling. This upgraded replacement kit features advanced multi-lip sealing geometry and a reinforced casing to provide superior fluid retention and long-term protection against trail grit, water, and road salt.

Kit Highlights:

• Upgraded Design: Features an enhanced multi-lip rubber seal profile and rigid structural outer shell for a tighter, more resilient fit within the axle housing bore.

• Genuine Spicer OEM Quality: Manufactured to strict factory tolerances using high-grade, heat-resistant elastomer compounds designed to withstand continuous friction and aggressive gear oil additives.

• Essential Drivetrain Service: Highly recommended whenever installing an aftermarket locking differential, changing ring and pinion gear sets, or pulling the carrier for axle shaft maintenance.

• Direct Application Fit: Engineered as a direct mechanical upgrade for heavy-duty Ford Super Duty monobeam Dana 50 and Dana 60 front axle assemblies.
