OES: Original Equipment Specification (OES) A bolt-in replacement cam with stock cam timing is designed for riders with stock engines Does not require tuning Bolt-in stock Equivalent to HD® L-Grind 508: Bolt-in cam intended for stock engines with less than 10:1 compression ratio Quiet valvetrain with excellent low/mid range torque for touring and 2 up riding 510V: Bolt-in cam that works well with stock or ported heads Improved ramp design results in low valve train noise Meant for engines up to 96" and 10:1 compression ratio 3000–5000 rpm 520: A replacement part for S&S emissions certified engines, this is a short duration emissions cam with very little overlap to reduce emissions of unburned hydrocarbons Requires high lift springs and normal clearance checks 1000–4500 rpm (80"–96")

561: For 80"–96" engines at 9 5:1–10 5:1 compression ratio Provides strong midrange power 3000–5500 rpm

585V: A versatile cam for 80" to 96" engines with 10:1–10 5:1 compression, and larger engines with 9 5:1–10:1 compression ratios 3500–6000 rpm

600: An exceptional cam in any large displacement engine with 9 5:1 to 10 5:1 compression 3500–6000 rpm

631: For high rpm applications, an excellent choice for all street and racing engines with 11:1 and higher compression ratios Great performance cam, but expect more "wear and tear" on valve train components Valve spring spacing and other normal clearancing checks required 4500–6500 rpm 640: For large displacement motors with compression ratios of 10 5–11 5:1, or smaller motors with 11:1–12-1 compression ratio Does not require as much compression as the 631 and provides a more linear power delivery 3000–6000 rpm
