The IAG Red Racing Timing Belt is engineered for use with all Subaru EJ series engines and is designed to exceed the strength and durability of the OEM timing belt. Constructed with high-strength Kevlar reinforcement and finished in a distinctive red color, this belt not only enhances engine bay appearance but is built to withstand the demands of high-horsepower and racing applications. It is a direct replacement for OEM timing belts found on 2002–2014 Subaru WRX, 2004–2021 Subaru STI, 2005–2012 Legacy GT, and 2004–2013 Forester XT models.

Extensive testing on IAG’s Spintron machine, along with real-world validation across IAG’s vehicle fleet, confirms consistent timing accuracy and exceptional durability under extreme conditions. These evaluations ensure the belt delivers reliable performance in both street-driven and competition-focused builds.

The Kevlar-reinforced construction is lightweight, resists stretching, and offers significantly improved strength and heat resistance compared to the factory belt. In addition, the belt is manufactured using EPDM rubber, which provides excellent resistance to ozone, weathering, cracking, and premature wear, allowing it to perform reliably in all climates. The timing belt teeth are formed from H-NBR grade rubber, chosen for its chemical resistance and high mechanical and dynamic strength, ensuring long service life in demanding environments.
