Stage X Alloy / Steel Vernier Cam Pulley Set GDA 2001+

Subaru Adjustable Vernier Camshaft Pulleys

These adjustable vernier camshaft pulleys are made for high-performance and competition Subaru engines, giving accurate cam timing adjustment with strength and reliability. Fits GC8/GF8 1999-2001.

They have an anodised black alloy outer and a stainless steel inner hub, built to withstand motorsport use while holding alignment and durability over long operating cycles. The one-piece integrated belt guide keeps the belt tracking securely at high rpm, reducing the risk of belt walk under extreme conditions.

Laser-etched incremental timing markings make cam timing adjustment quick, repeatable and accurate, whether during engine setup or trackside. The OEM stock tooth profile is fully compatible with standard Subaru timing belts, and the fine textured belt grip surface improves belt engagement and stability.

Supplied with genuine ARP high-strength bolts, which give better clamping force and long-term reliability than standard fasteners.
