S-Tec SP00055 Transfer Case Shaft Seal

The S-Tec SP00055 is a replacement shaft seal designed for transfer case applications. This OE-quality seal is engineered to maintain a reliable fluid barrier within the transfer case assembly, preventing fluid leaks and protecting internal drivetrain components from contamination and premature wear.

The transfer case shaft seal surrounds the output shaft to allow for rotation and power transfer while maintaining proper fluid levels inside the transfer case housing. A failed or hardened seal can allow fluid to escape and permit dirt, debris, and moisture to enter the assembly, leading to accelerated wear and potential drivetrain damage.

• OE-quality transfer case shaft seal replacement
• Engineered to maintain proper fluid retention and prevent leaks
• Protects transfer case internals from contamination
• Manufactured by S-Tec, a specialist in transfer case and drivetrain components
