About this part

Product Details

These S&S Cycle piston rings are precisely machined to be 0.010 inches undersize, ensuring a snug fit in your 2007 and newer Big Twin engine's cylinders. Proper ring seal is crucial for maintaining compression, controlling oil consumption, and getting the most power out of your engine. When you're rebuilding the top end or refreshing your engine, using rings that match the cylinder bore size is key to a successful build.

S&S Cycle is known for making well-built engine components, and this piston ring set is no exception. They are designed to create a solid seal between the piston and the cylinder wall, which helps prevent combustion gases from escaping into the crankcase and oil from entering the combustion chamber. This set comes as a 2-pack, meaning you get enough rings for two pistons, which is standard for most V-twin engine configurations.
