Camshaft, Pro Mod, Single AVCS, EJ25

CJM Components Pro Mod Camshaft

These cams were designed and developed as high-output Pro Mod camshafts for Subarus producing 1150+ HP. Upgrading to performance camshafts allows the engine to breathe more efficiently by optimizing valve timing and lift, dramatically increasing airflow, improving high-RPM power, and supporting extreme horsepower levels far beyond the limits of factory cams. These cams also feature dual lobe centerlines on both the intake and exhaust valves, improving flow characteristics and further enhancing overall engine performance. The CJM Pro Mod profile is engineered for serious power while maintaining the consistency and stability required in high-performance applications.

Upgraded valve springs are required, and the CJM Pro Mod Dual Spring Package is strongly recommended to ensure proper valve control and reliability at high RPM.

Break-In: A proper camshaft break-in procedure using high-zinc oil is mandatory to ensure long-term durability and maximum performance.

Professional Installation: Installation should be performed by an experienced technician familiar with Subaru timing systems and AVCS functionality.

Fitment: These CJM Pro Mod cams are designed exclusively for USDM Subaru engines equipped with Single AVCS (Intake Only).
