• Engineered as a high-performance, ultra-reliable torque monster with a 4-1/8" bore x 4-1/8" stroke profile
• Short-stroke performance design reduces cabing vibration, lowers operating friction, and extends total engine longevity
• S&S 585 gear drive easy start cams eliminates the stock chain-drive vulnerabilities while guaranteeing easy starts without manual compression releases
• High-flow S&S TC3 oil pumps and cam plates deliver ultra-consistent oil pressure, higher feed capacities, and superior scavenging compared to factory setup
• Heads are custom machined to use stock-length manifolds, factory EFI throttle bodies, and standard-location air cleaners
• Built using heavy-duty 356-T6 aircraft-grade aluminum casting architectures to eliminate case twist under high loads

Notes

• Does not include an intake manifold, throttle body, fuel injection, or ignition system. Designed to reuse your existing stock or aftermarket components.
• Installation on '07-'16 Harley-Davidson Touring models requires the separate purchase of an S&S oil line kit.
• Designed strictly for FL rubber-mount chassis layouts. Will not fit Harley-Davidson Softail models
