JE Pistons Ring Sets 1.0-1.2-2.8-86.25

When you're rebuilding the top end of your engine, getting the right piston rings is crucial for proper sealing and performance. This set from JE Pistons is designed to help maximize horsepower by ensuring a tight seal for combustion pressure. They're a popular choice for builders looking to get the most out of their engine rebuilds.

This particular set features a file-fit design, meaning you'll need to gap the rings to your specific cylinder bore size for optimal performance. The top ring is made from carbon steel nitride, known for its durability and ability to handle high temperatures. The second ring is ductile iron phosphate, which helps with oil control and sealing. For the oil ring, you get a low-tension carbon steel nitride design, which reduces drag and further aids in sealing. These materials and thicknesses are chosen to work together for a solid seal.

Because these are file-fit rings, they require careful measurement and filing to achieve the correct end gap for your engine's bore. This allows for a custom fit that stock, pre-gapped rings can't always match, especially in performance applications. Remember, these rings are not CARB approved and cannot be shipped to California.
