    MAHLE Original plasma-moly steel top rings provide the ultimate in tensile strength, hardness, and fatigue resistance. The MAHLE Original SAE 9254 steel is combined with proprietary plasma face coating to extend life, eliminate ring breakage, reduce side wear and minimize groove pound out problems. The smaller cross-section of the steel ring allows the top ring groove to be moved closer to the top of the piston. This reduces the crevice volume portion around the top ring land for reduced unburned fuel. Smaller cross-sections mean lower ring mass; this lighter ring design will better tolerate inertial forces and thus seal against the bottom of the ring groove more effectively. The smaller cross-section permitted with higher strength material greatly improves the ability of the ring to conform to cylinder bore distortion often found in today’s high output, high RPM engines.

  • Mahle Original performance piston rings sets are the most technically advanced and rigorously tested than any other piston ring manufacture. Current racing engines demand piston rings to operate at higher operating rpm, higher compression ratio, and higher temperatures from race to race and remain dependable. These factors require rings that are stronger, lighter, seals better, and resist wear under extreme conditions.

    Features
  • Recommended for street, racing, or marine applications
  • Barrel faced top ring offers instant break-in and maintains contact with the cylinder wall as the piston rocks slightly at TDC and BDC.
  • Napier THG (hook groove) second compression ring provides superior oil control by scraping cylinder walls of oil and providing a reservoir on each down stroke.
  • CP-20 oil control ring, named by its 20 degree ear angle, and exclusive feature that provides the absolute best cylinder wall seal.
  • Available in different compression ring materials consisting of cast iron, ductile iron, gas nitride stainless steel, steel alloy.

    Motor Vehicles

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.

    Tools:

    WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
