Genuine Porsche Differential Input Seal

The Genuine Porsche Differential Input Seal (also called a differential pinion seal or diff input shaft seal) is an original equipment replacement part. It keeps gear oil inside the differential housing where the driveshaft or propshaft connects. It also helps keep dirt, water and road debris out.

Key Features:

• Genuine Porsche original equipment part, built to factory specifications
• Seals the differential input shaft to help prevent gear oil leaks
• Helps protect internal gears and bearings from contamination
• Made from oil-resistant sealing materials designed for the heat and rotation of a differential
• Helps maintain correct lubricant levels for smooth, reliable drivetrain operation

A worn or leaking input seal can lead to low gear oil, noise and premature differential wear. Replacing it with a genuine Porsche seal helps restore proper sealing and protects the drivetrain. Select the child item that matches your application.
