IAG Performance / RCM Alloy Camshaft Sprocket 4 Piece Kit NON AVCS 2002-2005 WRX | High-Grade Aluminum | Precision Timing Upgrade
Overview
The IAG Performance / RCM Alloy Camshaft Sprocket 4 Piece Kit is a direct upgrade designed specifically for 2002-2005 Subaru WRX models equipped with non-AVCS engines. This kit replaces the factory Bakelite camshaft sprockets with a set of durable, lightweight aluminum alloy sprockets engineered to provide precise valve timing and long-lasting reliability. Ideal for enthusiasts looking to enhance engine durability and maintain optimal timing accuracy under demanding conditions, this kit is a solid choice for both daily drivers and high-performance builds.
Developed in collaboration with Roger Clark Motorsport, a leader in motorsport engineering, these sprockets are machined from a single piece of high-grade aluminum alloy and finished with a black anodized coating for corrosion resistance and durability. Unlike OEM plastic sprockets that can become brittle over time or aftermarket two-piece designs prone to failure, the IAG / RCM kit offers a robust, one-piece construction that ensures consistent performance and reduces the risk of catastrophic engine damage.
For Subaru WRX owners, especially those pushing their engines beyond stock power levels, maintaining precise camshaft timing is critical. This kit includes all four cam sprockets, including the rare left-hand intake sprocket that is no longer available from Subaru, ensuring a complete and reliable upgrade. The improved material and construction translate to enhanced engine longevity and confidence during spirited driving or track use.
