Why Replace as a Kit
Mixing old pulleys with a new belt is false economy. Replacing everything together restores proper belt tracking and tension, reducing noise and preventing unexpected failures.
Why Genuine Matters
Correct spring tension, bearing quality, and fitment — exactly how Subaru engineered it.
