S&S CYCLE T124LC Series Long Block Engine 310-0832A

The S&S Cycle T124LC Series Long Block Engine delivers the low-end torque and reliability you need for street performance without sacrificing everyday rideability. At 10.2:1 compression, this 124-cubic-inch powerplant generates real-world horsepower and torque gains while maintaining the easy-start characteristics serious riders demand. Whether you're building a performance touring bike or replacing a tired stock engine, the T124LC offers factory-backed quality with a 2-year warranty and domestically sourced components.

This is a complete long block engine—ready for your chosen fuel system and ignition setup. The specially machined cylinder heads accept stock-length intake manifolds without modification, and the breather vent locations remain in stock positions for seamless integration with your existing air cleaner. Installation requires an oil line kit (sold separately), but the bolt-on approach means you're not committing to extensive fabrication work.
