Ready to unlock serious displacement on your Twin Cam without a complete engine rebuild? The S&S Hot Set-Up Kit transforms your stock engine into a potent 124-cubic-inch powerplant using the original crankcases, giving you a cost-effective path to substantially increased horsepower and torque. This comprehensive kit includes every component needed—from premium forged pistons and precision cylinders to a complete cam package—so you're not hunting for parts across multiple suppliers.

Built by S&S Cycle in the U.S., this assembly demands respect and precision.

The investment pays dividends on both the street and the strip.
