JE Pistons Ring Sets 1.5-1.5-3mm RINGSET

This is a JE Pistons ring set, specifically the J612U6-3858 model, designed for 6-cylinder engines. These rings are crucial for sealing the combustion chamber, which directly impacts how much horsepower your engine can make. When the rings seal well, they keep the combustion pressure where it belongs, pushing the piston down and generating power, rather than leaking past the cylinder wall.

This particular set features a 1.5mm top ring, a 1.5mm second ring, and a 3mm oil ring, all made from iron phosphate. This material is known for its durability and ability to create a strong seal against the cylinder wall. The set is file-fit, meaning you'll need to gap the rings to your specific piston and cylinder bore dimensions during installation, a common practice for performance builds to ensure optimal sealing and prevent piston damage. JE Pistons uses the same ring technology that top racing teams rely on, which can lead to improved durability and reduced friction for more power.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Proper installation is key to achieving the benefits these rings offer, so refer to the manufacturer's instructions for gapping and fitting.
