S&S CYCLE 100" Power Package Engine Performance Kit — 100 ci, 4.000" bore, 10.5:1 compression – 99-06 Touring, 00-06 Softail, 99-05 Dyna, 01-02 CVO

The 100" Power Package Engine Performance Kit provides a complete crank and valvetrain upgrade for riders seeking stronger, more reliable power. Made in the USA, the kit contains big-bore cylinders, matched piston kits, Easy Start cams, Quickee pushrods, a TC3 cam support plate with TC3 oil pump, and precision hydraulic tappets. ⚙️

• Two big-bore cylinders with low-friction ductile cast iron liners — bolt-in installation with no crankcase machining, balancing, or splitting required.
• Piston kit with front and rear pistons, piston pins, pin clips and installation tool, plus full ring packs to deliver the advertised compression.
• S&S 585 Easy Start® cams calibrated for strong street performance and reliable idle characteristics.
• Adjustable Quickee pushrods with chrome tubes for precise valvetrain setup.
• TC3 cam support plate and TC3 oil pump machined from aluminum forgings to help ensure consistent oil pressure and engine longevity.
• Precision hydraulic tappets with close tolerances to reduce leak-down and quiet valve-train noise from start to shutdown.

This kit can be used with compatible stock heads to increase displacement and overall performance. Not for '06 Dyna. Not compatible with S&S 79 cc Super Stock® heads. '99-'04 Twin Cams will require the additional purchase of a valve spring kit (sold separately). Not recommended for Tri-Glide or other three-wheel models due to lugging characteristics. 🔧
