JE Pistons Ring Sets 1.2-1.2-2.0-87.00 PVD

When you're rebuilding the top end of your engine, getting the piston rings seated right is crucial for sealing combustion pressure and making good power. These file-fit piston rings from JE Pistons are designed to help you achieve that precise seal. They come in a 1.2mm top ring, 1.2mm second ring, and a 2.0mm oil ring configuration, with a bore size of 87.00mm, and are ready for you to file to your exact piston groove clearance.

What sets these rings apart is the PVD (Physical Vapor Deposition) coating on the top ring. This advanced coating is known for its incredible hardness and low friction, which translates to better sealing, less wear, and improved horsepower by reducing drag in the cylinder. The second ring is phosphate coated, and the low-tension oil ring is nitride treated, all working together to ensure a solid seal across a variety of engine builds. These are the same types of treatments used by top racing teams, offering a notable boost in durability and performance.

Remember, these rings are file-fit, meaning you'll need to carefully measure and file the end gap to match your specific piston and cylinder bore dimensions. This ensures optimal performance and prevents issues down the road. Please note that these rings are not CARB approved and cannot be shipped to California.
