JE Pistons Ring Sets 1.0-1.2-2.8-3.386

When you're rebuilding the top end of your 6-cylinder engine, getting the piston rings seated correctly is crucial for sealing combustion pressure and maximizing horsepower. This set from JE Pistons is designed for that purpose, offering a file-fit design that allows you to precisely tailor the end gap for your specific application. This attention to detail is what helps ensure a solid seal, preventing blow-by and keeping your engine running efficiently.

This particular set features a 0.0394-inch thick carbon steel nitride top ring, a 0.0472-inch ductile iron phosphate second ring, and a low-tension 0.1102-inch carbon steel nitride oil ring. The combination of materials and thicknesses is chosen to work together for effective sealing and reduced friction. JE Pistons is well-known for the same precision services they offer to top racing teams, and these rings reflect that commitment to performance and durability. The file-fit nature means you'll need to carefully measure and file the end gaps to the correct specification for your cylinder bore, a common practice for performance engine builds.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions for proper gapping and seating procedures.
