The IAG/RCM alloy cam sprocket is more than an upgrade—it’s the replacement part you’ve been searching for. Designed for the cam on 2002–2005 Subaru WRX models, this high-strength steel sprocket was developed by IAG Performance and Roger Clark Motorsport. It replaces the now-discontinued OEM part (#13055AA070) and is built to match the rest of your engine’s original cam sprocket setup.
The IAG alloy camshaft sprocket is made from a single piece of high-grade aluminum, in contrast to most aftermarket options that consist of a failure-prone two-piece design. This design is superior to other aftermarket options that combine a toothed wheel and guide ring, which have a tendency to separate and fail. This sprocket also improves upon Subaru's OEM plastic Bakelite sprockets, known to become brittle and break apart, leading to catastrophic engine failure. For unmatched durability and performance in high-power applications, IAG’s alloy crankshaft sprocket is the ultimate choice.
Fits all 2002-2005 Subaru WRX.
