IAG / RCM Alloy Camshaft Sprockets (4 PCS) Kit For NON AVCS 02-05 WRX

The IAG / RCM Alloy Camshaft Sprocket Kit for Non-AVCS engines is the ultimate upgrade for your 2002–2005 Subaru WRX. Developed in collaboration with Roger Clark Motorsport and cut from a solid piece of aluminum alloy, these black anodized sprockets are built to outlast and outperform Subaru’s stock Bakelite design. Their lightweight yet durable construction delivers precise timing and long-term reliability, whether you’re daily driving or pushing your WRX to the limit.

The IAG Alloy Camshaft Sprocket Kit includes the left-hand exhaust, right-hand exhaust, and right-hand intake sprockets, and also comes with the hard-to-find, discontinued OEM left-hand intake sprocket—replaced with our machined billet aluminum version.

The IAG Alloy Camshaft Sprocket Kit is built tough, featuring sprockets machined from a single piece of high-grade aluminum—unlike most aftermarket two-piece designs that can fall apart under stress. Our kit outperforms those that combine a toothed wheel and guide ring, which are prone to separating and failing. Even Subaru’s OEM plastic Bakelite sprockets don’t hold up, becoming brittle and risking catastrophic engine failure. For serious durability and top-end performance in high-power setups, the IAG Alloy Camshaft Sprocket Kit is the clear choice.

IAG Performance and Roger Clark Motorsports have teamed up to offer these specialized Alloy Camshaft Sprockets. With over 60 years of racing and competition experience, along with more than 30 years of automotive product research and development, RCM has long been established as an industry leader. Engineered for dependability, the IAG Alloy Camshaft Sprockets raise the bar for quality and performance.
