T124 Long Block Engine - Black - FXD | FXDWG
The S&S Cycle T124 Long Block Engine offers high-performance power and reliability for Harley-Davidson FXD and FXDWG models. Designed with precision machining and high-quality components, this engine provides excellent strength and durability for demanding riding conditions. Its special head machining ensures compatibility with stock-length intake manifolds, particularly the S&S manifold size 410, making installation straightforward for enthusiasts looking to upgrade without extensive modifications. The engine includes Super Stock™ heads, a high-flow oil pump, crankcase, cam cover, and easy start 640 gear drive cams, all assembled to deliver impressive torque and horsepower.
The T124 engine features a stock style breathing system that pairs seamlessly with stock and most performance air cleaners, maintaining the classic look while enhancing airflow. Its unique design adjusts the breather vent bolt position to match the stock location, allowing stock-style air cleaner back plates to bolt directly onto the engine. Additionally, the engine's non-stock cylinder length is compensated through precise machining, ensuring proper fitment with your existing manifold and throttle body. Built in the USA with quality craftsmanship, this long block is an ideal upgrade for riders seeking increased power without sacrificing compatibility or ease of installation.
Note that this engine requires an oil line installation kit and does not include fuel system or ignition components. Whether you’re customizing your Harley or replacing an existing engine, the S&S Cycle T124 long block provides a reliable foundation for high-performance riding, backed by the brand's reputation for quality and innovation.
