Everything Needed for a Timing Belt Job in One Kit

A proper timing belt service involves more than just the belt itself, requiring the tensioner, idler pulleys, and often the water pump to be replaced at the same interval since they're all similarly aged and difficult to access again without redoing much of the same labor. Gates bundles all of these components into one complete kit specifically for the 2008-2012 STI, so there's no need to separately source and cross-reference part numbers for each individual piece. That completeness is exactly what makes a timing belt job efficient rather than a multi-trip parts hunt. It's the kind of upgrade that quietly does its job without ever needing a second thought.

OE-Quality Components From an OE Supplier

Every component in this kit is built to the same OE-quality standard Gates supplies directly to automakers, so you're not compromising reliability to save a trip to a dealer parts counter. Including the water pump in this kit means it gets replaced proactively at the same interval as the timing belt, which is exactly when a water pump failure becomes most likely anyway given its similar wear-driven service life. It's the complete, correct way to handle a timing belt interval service on this specific STI generation. That's real, functional engineering, not just a marketing claim.
