Detailed Product Description
The National 6358 wheel seal is constructed from nitrile, a material known for its resistance to oil, heat, and wear, making it suitable for heavy-duty applications in Chevrolet and GMC trucks. Its bi-directional lip design ensures a tight seal around the shaft, preventing oil leaks and ingress of dirt or moisture. The Redicoat treatment adds a protective layer to the seal’s metal components, reducing the risk of corrosion and extending service life. This 47 series oil seal fits precisely within a housing bore of 4.625 inches, matching the dimensions required for models such as the Chevrolet C3500 and GMC P3500.

Installation Notes and Tips
- Ensure the housing bore and shaft are clean and free of debris before installation
- Use proper tools to avoid damaging the seal lips during installation
- Verify the seal orientation matches the bi-directional lip design for optimal sealing
- Check shaft and bore dimensions to confirm compatibility with part number 6358
- Apply a light coat of lubricant on the seal lip to ease installation and prevent damage
