JE Pistons Ring Sets 1.0-1.2-2.8-85.49

JE Pistons is well-known for making high-performance engine components, and their piston ring sets are a prime example of that expertise. This particular set, part number JG1004-3366, is designed for 4-cylinder engines and features a file-fit design, meaning you can precisely match them to your cylinder bore for optimal sealing. They are built to maximize horsepower by ensuring a tight seal for combustion pressure.

This set includes 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. The nitride coating on the top and oil rings helps improve durability and reduce friction, which can lead to noticeable gains in power and better ring seal. These are the same types of services and materials used by top racing teams, now available for your build.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitting and break-in procedures.
