Chris Rivas 474 Camshaft

Chris Rivas 474 Camshaft — ROCKET PERFORMANCE GARAGE LLC

Unlock aggressive torque and broad power delivery for your Milwaukee-Eight build with the Chris Rivas 474 camshaft. Engineered specifically for four-valve Harley-Davidson heads, the 474 profile extracts maximum performance from smaller multivalve ports while remaining a direct bolt-in upgrade for many applications.

• Optimized 4-valve lobe design: New cam lobe profiles tailored to multivalve flow characteristics for improved midrange and top-end response.
• Bolt-in fitment: Low-lift 444, 464 and 474 cams offer easy installation and deliver predictable power where you ride most.
• Big-inch power: 474 is ideal for high-compression 114ci+ builds, providing strong torque and usable horsepower from 1800–6000 RPM.
• For serious builders: The 544 variant is available for those chasing maximum power in large-displacement motors.

Installation notes: To realize the full potential of the 474 camshaft, pair with a performance intake, exhaust system, and professional EFI tuning. Many world champions and speed record holders rely on Chris Rivas designs — a proven choice for riders seeking reliable, race-proven gains.
