JE Pistons Ring Sets 1.0-1.2-2.8-2.874

JE Pistons has a strong reputation for building high-performance engine components, and this JG1004-2874 piston ring set is a great example of that. These rings are built to maximize horsepower by creating a precise seal for combustion pressure within your engine. They are designed for 4-cylinder applications and come in a file-fit style, meaning you can fine-tune the end gap for your specific build.

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 reduce friction and improve the overall seal, which can lead to gains in durability and power. The same custom ring services used by top racing teams, like back cutting and PVD coating, are available from JE Pistons, though this specific set is ready to install as is.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your 4-cylinder engine and looking for a well-built set of piston rings, this JE Pistons set is a solid option.
