S&S Piston Rings

22 products — part of all Piston Rings

S&S Cycle piston rings are matched to S&S piston and cylinder bore specifications, designed to seat correctly and seal the combustion chamber on Harley-Davidson engines that have been built or rebuilt around S&S components. Ring gap, tension, and material are selected for the temperatures and pressures that S&S pistons generate — particularly relevant for performance builds where compression ratios are higher than factory and oil control under hard acceleration matters. Using S&S rings in an S&S engine build avoids the compatibility variables that come with mixing ring brands across a precision engine specification, and ensures the warranty and support chain stays intact when S&S provides technical assistance on a build. Iron City Motorcycles in Leeds stocks S&S engine components including pistons, cylinders, and piston rings so that customers building on an S&S foundation can source the complete bottom-end assembly from one trusted supplier.
