910-0642 88" to 100" conversion cylinder & piston kit. Silver

This S&S Sidewinder kit is the ultimate bolt-on performance upgrade for the early Twin Cam era, taking your stock 88 inch motor up to a full 100 cubic inches. These silver finished aluminum cylinders feature a 4 inch big bore design that works perfectly with your stock 4 inch stroke flywheels. Because it is a bolt-on kit, you can skip the engine removal and case boring, saving a massive amount of shop time. When paired with performance cams and a free-flowing exhaust, this kit is capable of pushing your output to the 100 horsepower mark. It provides a significant jump in torque and passing power while maintaining a stock-like appearance. This kit fits 1999 to 2006 88 inch Twin Cam models.
