The product includes spare piston rings, which include:

• 2x Top compression rings
• 2x Second compression rings
• 2x Expander rings
• 4x Steel rails

The top compression rings have a barrel shape with a casting coating, helping the heat transfer process between the piston and the cylinder wall. They control the gases in the combustion chamber, allowing the piston to transfer energy from the expanding combustion gases to the crankshaft.

The second compression rings feature an inverse torsional conical shape, supporting lateral sealing and preventing oil from entering beneath and behind the ring, leading to better oil economy. The modern design of the inverse torsional ring along with the conical machined surface doubles the lower edge of a positive torsional ring.

The oil control rings are three-piece with flexible ventilation, allowing the construction of rails with a small cross-section for better fit in the cylinder. They provide uniform pressure through four steel rails and two expanders, ensuring positive oil control.

Made in the USA. Several rings for two pistons are included unless otherwise stated. Two rings per groove, except for the rails, which will be two rail rings per one expander ring.
