JE Pistons Ring Sets 1.2-1.5-3.0-86.00

When you're rebuilding the top end of your engine, getting the piston rings just right is crucial for sealing combustion pressure and making good power. This set from JE Pistons is designed for an 86.00mm bore, offering a file-fit option so you can achieve a precise seal in your cylinders.

The rings are constructed with a 0.0472-inch carbon steel nitride top ring and a 0.0591-inch iron chrome second ring, both known for their durability and ability to handle high temperatures. The low-tension oil ring, also carbon steel nitride at 0.1181 inches thick, helps manage oil consumption effectively. These are the same types of ring services used by professional racing teams, aiming for reduced friction and improved durability.

Keep in mind that these rings are file-fit, meaning you'll need to carefully gap them to your specific cylinder bore and piston application. This process is essential for optimal performance and to prevent damage. Please note that this part is not CARB approved and cannot be shipped to California.
