Upgrade your early-model Subaru’s valvetrain with the IAG Alloy Camshaft Sprocket, engineered by Roger Clark Motorsport for superior durability and performance. Designed as a direct replacement for the left-hand exhaust cam sprocket on Version 1 through 4 WRX and STI models, this upgraded component eliminates the failure-prone plastic used in OEM designs.
Unlike the brittle Bakelite factory sprockets or less reliable two-piece aftermarket versions, the IAG sprocket is precision-machined from a single billet of high-grade aluminum alloy for maximum strength in high-performance builds.

High-Strength Design: One-piece construction from high-grade aluminum alloy for superior reliability
