Differential Seal Kits
Differential seal kits contain all the rubber seals needed to stop gear oil leaks at the pinion, axle shaft flanges, and carrier housing. Seals harden and crack over time from heat cycling and age, making periodic replacement an important part of axle maintenance, especially after a re-gear, fluid flush, or drivetrain swap where components are disturbed.Popular Differential Seal Kit ApplicationsSeal kits are available for all major axle platforms including Dana 30, Dana 44, Dana 60, GM 7.5 and 8.5-inch, Ford 8.8-inch, Ford 9-inch, Toyota 8-inch, and Chrysler 8.25 and 9.25-inch differentials. Kits from National Seal, Timken, and Yukon Gear supply OEM-quality or upgraded lip seal material that resists gear oil breakdown better than factory seals.What seals are included in a differential seal kit?A full differential seal kit typically covers the pinion seal, axle shaft seals for both sides, and sometimes the carrier or housing seals depending on the axle design. Some kits also include ...
