IAG offers a complete timing system package that combines the IAG Red Racing Timing Belt, Billet Timing Belt Guide, and V2 Competition Series “WRC Style” Tensioner for 2004–2021 Subaru STI, 2002–2004 WRX, 2004–2013 Forester XT, and 2005–2012 Legacy GT models. This package is designed to improve timing stability and durability in both high-performance street builds and demanding motorsports applications.

The package includes the IAG Billet Timing Belt Guide, an effective safeguard against timing belt derailment on Subaru EJ series engines. Designed and manufactured in IAG’s Westminster, Maryland facility, each guide is CNC machined from a single piece of 6061 billet aluminum and finished with a black anodized coating for corrosion resistance and long-term durability.

Also included is the IAG V2 Competition Series “WRC Style” Timing Belt Tensioner. This upgraded tensioner utilizes a proven design inspired by earlier Subaru motorsports applications and incorporates an additional roller to better control belt tension and timing accuracy. The billet aluminum base is CNC machined in-house and anodized black for added protection, while NTN OEM-style rollers are used to ensure consistent reliability under high RPM and high load conditions.

Completing the package is the IAG Red Racing Timing Belt, engineered for all Subaru EJ series engines. This belt is optimized for strength and designed to maintain stable tension even as heat expansion occurs in high-power, high-RPM environments. Constructed with Kevlar reinforcement, it is significantly stronger and more heat resistant than the OEM timing belt. EPDM rubber construction ensures durability and consistent performance across all climates, while H-NBR grade rubber belt teeth provide excellent chemical resistance and mechanical strength for long service life.
