JE Pistons Ring Sets 1.0-1.2-2.8-92.25

JE Pistons has a long history of making top-tier engine components for racing and performance applications. This JG1008-3632 piston ring set is built to help your engine make the most horsepower by ensuring a tight seal against combustion pressure. They are designed to be file-fit, meaning you can precisely adjust them to your specific cylinder bore for an improved seal.

This set features a 0.0394-inch thick carbon steel nitride top ring, a 0.0472-inch ductile iron phosphate second ring, and a 0.1102-inch low-tension carbon steel nitride oil ring. These materials and thicknesses are chosen to balance sealing, friction reduction, and durability. The same precision services used by top racing teams are available from JE, offering gains in durability and power through reduced friction and better ring seal.

Because these are file-fit rings, they require careful installation to ensure they are properly gapped for your engine's cylinders. Please refer to the manufacturer's installation instructions for detailed guidance. Note that this part is not CARB approved and cannot be shipped to California.
