JE Pistons Ring Sets .0394 AH Top Ring / .0472 AH Ring 2 / 3.0mm Oil Ring / 4.060 Bore

JE Pistons has a solid reputation for making high-performance engine components, and this piston ring set is no exception. They're built to help your engine seal combustion pressure effectively, which is key to getting the most horsepower out of your build. This particular set is designed for a 4.060 inch bore and comes with file-fit rings, meaning you'll need to gap them yourself to perfectly match your cylinder walls and intended use. It includes a .0394 inch thick top ring and a .0472 inch thick second ring, both made from carbon steel nitride for durability and sealing. The oil ring is a 3.0mm low-tension carbon steel nitride design, also chosen for its sealing capabilities and reduced friction.

When you're rebuilding an engine, the details matter, and these rings are made with the same precision that top racing teams rely on. The file-fit nature gives you the control to achieve an optimal seal, which can lead to improved power and durability. While these are designed for performance, they are not CARB approved and cannot be shipped to California.
