JE Pistons Ring Sets 1.5-1.5-4.0-92.10

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for performance and longevity. These JE Pistons ring sets are built to ensure a tight seal between your pistons and cylinder walls, which is key to maximizing horsepower by preventing combustion pressure from escaping. They come in a wide variety of sizes and configurations to match different engine builds.

This particular set features a 0.0591-inch thick carbon steel nitride top ring and a 0.0591-inch iron chrome second ring. For the oil ring, it uses a 0.1575-inch low tension carbon steel nitride design. These materials and thicknesses are chosen to help reduce friction and improve the overall seal, contributing to both power gains and better durability. JE Pistons uses the same ring services that top racing teams rely on, like back cutting and PVD coating, which can offer notable improvements in how well the rings seal and how long they last.
