The S&S Cycle Power Pack is a performance kit built around 4.32" big-bore cylinders, which increase displacement for riders looking to add more output to their V-twin. The kit brings together the cylinders, a matched camshaft, a cam plate, and an oil pump, so the core cam chest components are supplied as one package.
Riders choose this kit because the parts are designed to work together as a system rather than as separate purchases. The camshaft and cam plate are matched for timing, and the included oil pump is intended to improve lubrication. The complete cam chest package is meant to make the upgrade more straightforward than sourcing each component individually.
The kit is intended as a bolt-on upgrade, giving a defined path to more power without requiring a full engine rebuild. Because it is a significant change to the engine, a professional tune is recommended, along with a proper fuel management system and dyno tuning, to help the upgraded engine perform at its best.
For off-road / closed-course race use only.

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!
