RCM Subaru Adjustable Vernier Camshaft Pulleys are engineered for high-performance and competition Subaru engines where precise cam timing control is critical. Designed and manufactured to meet the demands of motorsport, these pulleys allow accurate, repeatable adjustment while maintaining exceptional strength and long-term reliability.
Each pulley is constructed with a high-strength anodised alloy outer and a stainless steel inner hub, providing excellent resistance to wear, heat, and repeated adjustment cycles. This combination ensures the pulleys maintain precise alignment even under extreme RPM and high-load conditions commonly encountered in track, rally, and competition use.
An integrated one-piece belt guide is built directly into the pulley design, ensuring secure belt tracking and minimising the risk of belt walk at high engine speeds. The OEM stock tooth profile guarantees perfect compatibility with standard Subaru timing belts, while the fine textured belt surface improves belt grip and stability during aggressive engine operation.
Laser-etched incremental timing markings make cam timing changes quick, clear, and repeatable, whether setting up an engine on the dyno or making adjustments trackside. Supplied with genuine ARP high-strength bolts, these pulleys deliver superior clamping force and reliability compared to standard fasteners, ensuring timing settings remain locked in place.
Ideal for fast road, track, rally, and full competition builds, RCM Adjustable Vernier Camshaft Pulleys provide the precision, durability, and confidence required by serious Subaru enthusiasts and professional engine builders.
