JE Pistons Ring Sets 1.0-1.2-2.8mm 3.445

JE Pistons offers this piston ring set, designed for a 1-cylinder application with a 3.445-inch bore. These rings are built to seal combustion pressure effectively, which is key to getting the most horsepower out of your engine. They come in a 1.0mm top ring, a 1.2mm second ring, and a 1.102-inch (2.8mm) oil ring, with a file-fit design for custom applications.

The top ring is made from carbon steel with a chrome finish for durability, while the second ring is iron phosphate. The low-tension oil ring is also carbon steel with chrome. These materials and the specific ring thicknesses are chosen to work together for a solid seal. JE Pistons uses the same techniques for these rings that top racing teams rely on, aiming for improved durability and reduced friction.

This set is intended for engine rebuilds where precise ring seal is critical. Please note that this part is not CARB approved and cannot be shipped to California.
