900-0569 124" Twin Cam Softail hot set-up kit with heads. Black

Transform your 2007 to 2017 Softail into a high-performance beast with this S&S 124-inch Hot Set-Up kit. This comprehensive package upgrades your stock 96 or 103-cubic-inch engine to a massive 124-inch displacement. The kit includes stroker flywheels, big bore cylinders, and flat-top pistons that achieve a 10.8:1 compression ratio when paired with the included 91cc high-flow heads. To manage the power, S&S includes 640 Easy Start gear-driven cams, ensuring the engine breathes properly while remaining easy to start with stock components. Please note that the stock cases must be machined to accept the 4-1/8 inch cylinders. This kit is finished in black wrinkle with highlighted fins and requires a high-performance EFI tuner and a larger throttle body to reach its full potential.
