2.750 Inner Axle Seal

The 2.750 Inner Axle Seal from SEALS-IT is a critical fluid containment component designed to prevent differential fluid loss and contamination at the inner axle assembly. Whether you're rebuilding a worn differential, replacing a leaking seal during routine maintenance, or upgrading a vehicle with a history of fluid seepage, this precision seal restores the integrity of your axle's hydraulic barrier. Inner axle seals endure constant rotation, temperature cycling, and pressure fluctuations—making OEM-quality replacement essential for long-term driveline reliability and performance.

Engineered with a 2.750-inch bore diameter, this seal matches the inner axle shaft specifications required by many domestic and import platforms. SEALS-IT products are manufactured to exacting tolerances, utilizing elastomer compounds formulated to resist mineral and synthetic differential fluids across a wide operating temperature range. The seal's dynamic lip geometry creates a consistent contact patch against the rotating shaft, minimizing friction wear while maximizing sealing efficiency. Compact at 3.05 x 2.25 x 3.1 inches and weighing just 0.43 lbs, installation is straightforward and fits within standard axle housing assemblies without modification.

Mechanics and DIY enthusiasts rebuilding differentials, addressing fluid leaks, or performing preventative maintenance will find this seal compatible with vehicles using 2.750-inch inner axle shafts across various domestic truck and SUV platforms. Proper installation requires careful shaft alignment and use of appropriate seal installation tools to avoid lip damage during seating. This SEALS-IT component is ideal for restoring factory-spec sealing performance and is commonly paired with other differential service items during a full rebuild. Always verify shaft diameter compatibility with your specific vehicle's service manual before ordering.
