JE Pistons Ring Sets 1.2-1.2-2.0-86.00 PVD RS

JE Pistons offers this Piston Ring Set, part number JG1204-3386, designed to help your engine seal combustion pressure effectively. This set is built with a 0.0472-inch carbon steel PVD top ring, a 0.0472-inch carbon steel phosphate second ring, and a 0.0787-inch carbon steel nitride low tension oil ring. The PVD coating on the top ring is a notable feature, often used by professional racing teams to increase durability and reduce friction, which can lead to improved power and a better ring seal.

These rings are file-fit, meaning you'll need to gap them to your specific cylinder bore during installation, a common practice for performance builds to ensure optimal sealing. The carbon steel construction with various coatings like PVD and nitride is chosen for its strength and ability to withstand the high temperatures and pressures inside the combustion chamber. This set is intended for 4-cylinder applications and is a solid option if you're rebuilding or upgrading your engine's top end.
