JE Pistons Ring Sets 1.2-1.5-3mm RING SET

What you get in this set are the piston rings themselves, ready to be installed on your pistons. Specifically, this set includes a 0.0472-inch thick carbon steel nitride top ring, a 0.0591-inch thick iron phosphate second ring, and a 0.1181-inch thick carbon steel chrome low-tension oil ring. These rings are file-fit, meaning you'll need to adjust their end gap to match your cylinder bore during installation, a common practice for performance builds to ensure a precise seal.

JE Pistons designs these rings to maximize horsepower by precisely sealing combustion pressure. The combination of materials and thicknesses in this set is chosen to work well in a wide variety of engines. The nitride treatment on the top ring and the phosphate coating on the second ring help with durability and reduce friction, which can lead to improved power and a better seal within the cylinder. While these are file-fit rings, the same services JE Pistons offers to top racing teams, like PVD coating and custom cutting, are available to enhance durability and reduce friction even further.

Remember that these rings are file-fit, so you'll need to measure your cylinder bore and adjust the ring end gap accordingly. This is a standard procedure for many performance engine builds. Also, please note that this product is not CARB approved and cannot be shipped to California.
