e. Improved Performance: A new, properly functioning pinion seal can help improve the performance of your differential by reducing leaks and maintaining optimal lubrication.

a. Limited Warranty: Aftermarket parts, including the National C391 seal, typically come with limited warranties, while OEM parts often provide longer coverage.

b. Quality Variability: There can be variability in the quality of aftermarket parts, although reputable brands like National generally maintain high standards.

c. Installation: Installing the seal can be a complex process, and improper installation could result in further damage or leaks. Thus, hiring a professional is advisable for some vehicle owners.
