Prevents seal leakage. Excellent sealing ability. Resists abrasives, corrosive moisture and other harmful contaminants from entering the machines. Offers superior service life. World-class manufacturing standards.
As my tests showed this seal did not last long and failed to prevent leaks. The only positive note is that it was relatively easy to install. However, the cons far outweigh the benefits as its low quality and lack of durability make it not worth the investment. There are definitely better options out there for bearings and seals in the performance car parts and accessories category. .
Pros
Durable and long-lasting
Cons
Difficult to install without proper tools and experience
Very easy to install! I am happy with my purchase! Autozone and Oreilly cost their rear main seals $44-80, refills $16. I have used Timken before, very strong, seals like the original seals.
