The Skunk2 Pro Stage 3+ Camshafts are engineered for race-built Honda B-Series VTEC engines (B16A/B, B17A, B18C) and deliver exceptional mid-to-top-end power. Offering 25+ horsepower gains and a 700 RPM higher power peak compared to the Pro 2+ cams, these high-lift camshafts are built for serious performance with full valvetrain stability. The seamless VTEC crossover and broad powerband make them ideal for competitive drag and circuit builds.

Built from newly revised chill-cast billet blanks, each camshaft undergoes CNC grinding with cubic-boron wheels and features wear-resistant hardened lobes. Fast Ramp and AMAX profile technologies ensure fast response, high lift velocity, and optimal valve control—maximizing power output without compromising reliability. These are professional-grade camshafts developed through years of motorsport success and in-house R&D.
