1.5-1.5-4mm RINGSET
JE Pistons Pro Seal piston rings feature barrel-faced top rings made from premium ductile iron. They also have a special high-tech, friction-reducing, plasma-moly inlay on the face that combines molybdenum, nickel, chrome, and trace elements. The results are higher temperature resistance, reduced wear, better ring sealing, and reduced flaking. The second rings are a taper-faced, reverse-torsional design with a special phosphate coating. The oil-control rings are available in your choice of either low or standard-tension types. Choose the set designed for fitment on your engine application.
