JE Pistons Ring Sets 1.2/ 1.5/ 3.0mm/ 101.95 for Chevy LS Small Block

The 1.2mm top ring in this JE Pistons set is made from carbon steel with a nitride finish, designed to seal combustion pressure effectively. This specific ring set, part number JG3108-4010-4, is built for Chevy LS Small Block engines and features a 1.2mm top ring, a 1.5mm second ring, and a 3.0mm oil ring, all sized for a 101.95mm bore.

JE Pistons uses materials like carbon steel and iron phosphate in these rings to help maximize horsepower by ensuring a tight seal. The top ring is nitride-treated for durability, while the oil ring is chrome-plated carbon steel and designed for low tension, which helps reduce friction. These are file-fit rings, meaning you'll need to gap them to your specific application during installation, a common practice for performance builds to achieve optimal sealing and power.

This set is a solid option for rebuilding or upgrading your LS engine. Keep in mind 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.
