Product Description

The Gates TCKWP328RB is a premium racing-spec timing belt and water pump kit engineered to deliver a complete timing system overhaul for a variety of Subaru and Saab H4-engine vehicles - including WRX, WRX STI, Forester, Legacy, Outback, Baja, plus Saab 9-2X where applicable. Because it bundles the belt, tensioner, idlers, water pump, and all necessary hardware in one package, this kit simplifies timing-system maintenance or upgrade and ensures all components are compatible and correctly matched.

The reinforced "RPM" belt uses a nylon-reinforced tooth jacket and high-strength HSN compound for significantly improved resistance to heat, wear, and fluid exposure - this makes it well suited for interference engines, turbocharged applications, or performance-tuned builds, where durability under stress is critical. The included hydraulic tensioner and idlers help maintain proper belt routing and tension even under high RPM or boost conditions. Replacing the water pump at the same time helps avoid introducing new failure points after timing maintenance.

This kit is ideal for enthusiasts, DIYers, or performance-oriented owners who want a reliable, all-in-one timing refresh or upgrade. It's particularly well suited for turbocharged or high-output engines - but also makes sense for routine maintenance if you want to ensure long-term durability and avoid incremental failures due to belt or pump wear. Proper installation according to factory torque and alignment procedures is strongly recommended.
