S&S CYCLE T111 Long Block Engine 310-0834A

The S&S Cycle T111 long block delivers significantly more horsepower and torque than aging stock engines while maintaining compatibility with your existing fuel system and ignition—no expensive rewiring or fuel management upgrades required. This purpose-built engine combines proven S&S engineering with easy-start capability, reduced vibration from its short-stroke design, and a compact profile that simplifies installation on most applications. With a 2-year warranty and domestic manufacturing backing every component, you're upgrading to reliability and performance without compromise.

Built for riders who demand both immediate throttle response and long-term durability, the T111 features a high-flow oil pump, forged flattop pistons, and super stock heads and crankcase—the foundation for consistent power delivery whether you're cruising or pushing hard. The specially machined cylinder heads accept stock-length intake manifolds and factory air cleaner backplates, eliminating fitment headaches common with engine swaps. Large cooling fins maximize heat dissipation, and the gear-drive Easy Start 585 cams make cold mornings effortless.
