JE Pistons Ring Sets .043-.043-3.0-105.410

JE Pistons has a solid reputation for making high-performance engine parts, and this piston ring set is a great example of that. They're built to seal combustion pressure really well, which is key to getting the most horsepower out of your engine. This particular set is designed for 8-cylinder engines and features a file-fit top ring, meaning you can fine-tune the gap for your specific build. The top ring is made from carbon steel with a nitride finish, while the second ring is ductile iron with a phosphate coating, both chosen for their sealing capabilities. The oil ring is standard tension carbon steel with a chrome finish, helping to manage oil effectively.

What's notable about these rings is the attention to detail, using the same kinds of services that top racing teams like those in NHRA Pro Stock and NASCAR rely on. This can lead to improved durability and reduced friction, which translates directly to more power. The specific dimensions for this set are .043 inch for the top and second rings, and the oil ring is 3.0mm (which is about 0.1181 inches). The bore size this set is intended for is 105.410mm.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. If you're rebuilding an engine and looking for a well-built set of rings that can handle demanding use, these are a solid option.
