Spicer Front Inner Knuckle Vacuum & Outer Axle Dust Seal Kit for Ford Super Duty (Dana 60, 2005-2014)

Restore your truck's automatic four-wheel-drive engagement and protect your front axle components from harsh road debris with this genuine Spicer Inner Knuckle Vacuum and Outer Axle Dust Seal Kit. Specially packaged for 2005–2014 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with a Dana 60 front axle, this service kit includes the critical high-wear sealing components needed to overhaul a single side of your front drivetrain.

Heavy towing, commercial hauling, mud, and road salt place intense stress on your Super Duty's front axle sealing system. Over time, the outer dust seals degrade, allowing moisture and trail grit to slip inside the axle tubes, while hardened or torn inner knuckle seals destroy the vacuum pressure needed to lock your factory hubs. This premium kit replaces those weak points with trusted Spicer OEM engineering, ensuring an airtight seal and smooth component protection.

Kit Highlights:

• Complete Single-Side Service: Bundles the large inner knuckle vacuum seal (hub seal) and the matching outer axle shaft dust seal required to refresh one side.

• Genuine Spicer OEM Quality: Manufactured from premium, wear-resistant elastomer compounds engineered to endure extreme thermal expansion and maintain an airtight vacuum lock.

• Fixes Common 4WD Failures: Replaces worn, leaking hub seals to restore proper vacuum pressure for reliable automatic Pulse Vacuum Hub (PVH) engagement.

• Direct Application Fit: Precision-molded to fit seamlessly inside coil-sprung 2005–2014 Ford Super Duty Dana 60 front axle configurations.
