JE Pistons Ring Sets 1.2-1.5-3.0-102.41

JE Pistons is a well-known name for performance engine parts, and this piston ring set continues that tradition. These rings are built to seal combustion pressure effectively, which helps maximize horsepower. They come in a 1.2-1.5-3.0mm thickness configuration and are designed for a 102.41mm bore size, with a 0.040 inch undersize specification.

This particular set features a 0.0472 inch carbon steel nitride top ring, a 0.0591 inch iron phosphate second ring, and a 0.1181 inch carbon steel chrome standard tension oil ring. The file-fit design means you'll need to gap these rings yourself to precisely match your cylinder bore, a common practice for performance engine builds to ensure optimal sealing and prevent piston damage. This attention to detail is what top racing teams rely on.

Because these are file-fit rings, they are intended for engine rebuilds where precise measurements and custom fitting are part of the process. Please note that this part is not CARB approved and cannot be shipped to California.
