JE Pistons Ring Sets 99.75 Bore 79 Stroke 130.5mm 30.7mm C/D -17.0 Dome 405

JE Pistons has a reputation for building top-tier engine components, and this piston ring set is no exception. They're engineered to create a tight seal in your combustion chamber, which is key to getting all the horsepower your engine can make. This set is designed for a 99.75mm bore and features specific dimensions for the top, second, and oil rings, including a low-tension oil ring made from carbon steel with a chrome finish.

The top ring is 0.0472 inches thick and made of carbon steel with a nitride treatment, while the second ring is also 0.0472 inches thick and uses iron phosphate. These materials and thicknesses are chosen to work together for optimal sealing and reduced friction. JE Pistons also offers custom services, like those used by professional racing teams, to further improve durability and power, though this specific set is ready to install as-is for many applications.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and break-in procedures.
