d. Quality: National C450 bearings are manufactured using high-quality materials and precision manufacturing techniques to ensure durability and reliability.

a. Potential for Noise: Some customers have reported increased noise after installing aftermarket bearings, although this is not a universal issue.

b. Wear Rate: Aftermarket bearings may wear out faster than OEM bearings, leading to the need for more frequent replacements.

c. Lack of Warranty: National C450 bearings do not typically come with the same level of warranty coverage as OEM parts.

While National C450 17-26 transmission differential bearings offer affordability and availability, they may come with the trade-off of increased noise and potentially faster wear compared to OEM bearings.
