JE Pistons Ring Sets .043-.043-3mm Rings

JE Pistons is well-known for making serious engine components for racers and performance builders. This particular piston ring set, part number J71408-4040-5, is designed to help your engine make the most horsepower by ensuring a tight seal for combustion pressure. They are a file-fit set, meaning you'll need to gap them to your specific cylinder bore for optimal performance.

This set features a 0.043 inch carbon steel plasma moly top ring, a 0.043 inch ductile iron phosphate second ring, and a 0.1181 inch (3mm) carbon steel chrome low tension oil ring. These materials and designs work together to reduce friction and improve the seal within your cylinders. JE Pistons uses the same techniques for these rings that top racing teams like those in NHRA Pro Stock and NASCAR use, aiming for improved durability and power.

Because these are file-fit rings, they are intended for builders who want to precisely tune their engine's compression and sealing. Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper gapping and fitting procedures.
