JE Pistons Ring Sets 0.8-0.8-1.5-2.933

Starting with a 0.0315 inch carbon steel chrome top ring, this JE Pistons ring set is built for serious sealing. The second ring is also 0.0315 inches, made from ductile iron with a phosphate coating, and the low tension oil ring measures 0.0591 inches, also in carbon steel with a chrome finish. These rings are designed to precisely seal combustion pressure, which is key to getting the most horsepower out of your engine. JE Pistons offers a wide variety of ring sizes and materials, and they even provide custom services like back cutting and PVD coating, the same kind used by top racing teams, to improve durability and reduce friction.

This particular set is file-fit, meaning you'll need to gap the rings yourself to match your cylinder bore precisely. This is a common practice for performance builds where exact tolerances are crucial for optimal sealing and power. While these rings are well-suited for both street and racing applications, remember they are not CARB approved and cannot be shipped to California.
