Tomei Adjustable Cam Gear Exhaust AVCS Set – Subaru WRX 2006–2014 / STI 2002–2007 (Pair)

Tomei Adjustable Exhaust Cam Gear AVCS Set

Adjustable cam gears allow fine tuning of camshaft timing to maximise engine performance and tailor power characteristics for different driving conditions. Whether used with OEM or aftermarket camshafts, timing adjustments can help position the engine’s power band within the optimum RPM range for the application.

Duralumin Construction

Duralumin is used for both the outer gear and inner pulley section.

Superior Accuracy and Durability

Both the pulley and inner plate are precision milled from billet aluminium and finished in anodised red. The outer gear receives a hardening treatment for improved gear resistance while maintaining dependable contact with the timing belt to support precise engine timing.

Upgraded Appearance and Functionality

The redesigned markings make the gears easier to read and adjust. The curved centre design improves rigidity and appearance while reducing weight.

A Durable Alternative to Factory Gears

Factory plastic gears can deteriorate over time and may break apart during engine operation, with the potential to cause serious engine damage, particularly in a tuned engine. Replacing them with a durable alternative helps reduce this risk.
