DESCRIPTION

RCM Subaru Adjustable Vernier Camshaft Pulleys

RCM Subaru Adjustable Vernier Camshaft Pulleys are precision-engineered for high-performance and competition Subaru engines, delivering accurate cam timing adjustment with uncompromising strength and reliability.

Manufactured with an anodised black alloy outer and a stainless steel inner hub, these pulleys are designed to withstand the demands of motorsport use while maintaining precise alignment and durability over extended operating cycles. The one-piece integrated belt guide ensures secure belt tracking at high RPM, reducing the risk of belt walk under extreme conditions.

Featuring laser-etched incremental timing markings, the vernier design allows for quick, repeatable, and highly accurate cam timing adjustments during engine setup or trackside tuning. The OEM stock tooth profile guarantees perfect compatibility with standard Subaru timing belts, while the fine textured belt grip surface improves belt engagement and stability.

Supplied with genuine ARP high-strength bolts, these pulleys provide superior clamping force and long-term reliability compared to standard fasteners.
