Frequently Asked Questions

What's included in the Power Pack?

Cylinders, pistons, cam, cam plate, oil pump, gaskets, and all necessary hardware to complete the assembly.

Do I need to have my engine machined for this kit?

No — the Power Pack is designed for bolt-together installation without custom machine work on standard Harley cases.

Will I need a tuner after installation?

A fuel/air recalibration is strongly recommended to optimize performance and reliability with the increased displacement and cam specs.

What horsepower gain can I expect?

Actual power depends on your base engine, fuel system, and tuning. Contact S&S Cycle or a Harley performance shop for estimates on your specific model.

100 kit is sick! 10/5/1 compression is perfect for the 585 cams. Not going to burn the tires unless you bounce it, but at 2.7 K it pulls like a freight train. Super fun! Thanks S&S!
