- Includes top compression rings, second compression rings, and oil control rings
- Helps in the the heat transfer process between the piston and cylinder wall
- Controls combustion chamber gases allowing the piston to transfer the energy of the expanding combustion gases, to the crankshaft
- Promotes side sealing that prevents oil from being forced under and behind the ring resulting in better oil economy
- Reverse twist ring along with a taper-machined ring face duplicates the OD bottom side scraping edge of a positive twist torsional ring
- Three-piece design allows rails to be manufactured with a small cross sectional area for better conformability to bore
- Provides uniform pressure through four steel rails and two expanders assuring positive oil control
- Made in the USA
- Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.

- Two rings per groove, except for the rails that will be two rail rings per one expander ring.
