🔧 S&S 520 camshaft is dyno-, street- and track-tested to deliver reliable performance.
🏁 Hundreds of hours of testing on each cam ensure you get the best cam S&S produces, tuned for strong low- to mid-range power from 1,000 to 4,500 rpm.
⚙️ Designed for 80"–96" motors up to 10:1 compression, it works with hydraulic tappets and requires high-lift springs.
🇺🇸 Made in the USA. Installer must check coil bind, valve-to-valve clearance, valve-to-piston clearance and camshaft lobe-to-case clearance before final assembly.
