Skunk2 Pro Series Camshafts – Stage 3 – B-Series VTEC

Skunk2 Pro Series Camshafts – Pro 3+ (B-Series VTEC)

The Skunk2 Pro Series Pro 3+ Camshafts are engineered for advanced naturally aspirated and forced-induction Honda and Acura B-series VTEC engines, delivering exceptional top-end power and throttle response. Designed for professional-level builds, these camshafts feature Skunk2’s proprietary AMAX and Fast Ramp technologies to maximize valve acceleration, airflow, and overall efficiency at high RPM.

Each camshaft is CNC-ground from premium chill-cast blanks to ensure strength, precision, and consistency. The Pro 3+ profile is optimized for aggressive race and competition use, supporting power levels well beyond what milder profiles can achieve. When properly tuned with supporting valvetrain components, these cams allow engines to safely rev beyond 9,500 RPM while maintaining stable valve control.
