Overview
S&S Cycle T117 Cylinder Kits
S&S Cycle's T117 cylinder kits are an exceptional choice for riders who choose to re-work their bikes for more power. This 4 1/8 in. bore cylinder and piston kit replaces the cylinders and pistons on early production S&S T117 engines for 1999-2006 Big Twins. With top-of-the-line components, these S&S Cycle T117 cylinder kits contain the following: S&S 4 1/8 in. bore cylinders, forged pistons, rings, wrist pins, head and base gaskets. Pistons are flat topped design intended for use with S&S Super Stock cylinder heads. The cylinders are machined with the S&S bolt pattern and are intended for use in S&S crankcases used in early S&S T117 engines. Designed for 4 3/8 in. stroke flywheels, resulting in 117 in. displacement. For best performance expectations, appropriate camshafts, performance air cleaner, performance exhaust and fuel system tuning are required.
