CYLINDER AND PISTON KIT 4-1/8 S&S POLISHED

This 4-1/8" bore cylinder and piston kit replaces the cylinders and pistons on S&S V117 engines in Big Dog Motorcycles from 2005 through 2011. The kit contains S&S 4-1/8" bore cylinders and 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 S&S V117 engines. Designed for 4-3/8" stroke flywheels, resulting in 117" displacement. Cylinder finish is a polished aluminum. These are special order only and generally take 6-12 weeks. Call WSW to order.
