IAG Performance IAG / RCM Cam Sprocket (Left Hand Intake) for V1-4

This upgraded sprocket is designed for installation on 1994-1998 Subaru STI or 1992-1998 Subaru WRX left-hand inlet position for versions 1 through 4. These specialty sprockets were precisely engineered by Roger Clark Motorsport. Unlike Subaru's OEM plastic Bakelite sprockets, this sprocket is constructed from a single piece of high-quality aluminum alloy. The IAG Alloy Camshaft Sprocket features a lightweight design while maintaining optimal strength and durability for unparalleled performance in your Subaru. The IAG RCM Alloy Camshaft Sprocket is made from a single piece of high-grade aluminum, in contrast to most aftermarket options that consist of a precarious two-piece design. Our 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 unsurpassed durability and performance in high-power applications, IAG’s Alloy Crankshaft Sprockets are the ultimate choice.
