The Total Seal Conventional AP Steel Top Piston Rings are meticulously manufactured in-house to extremely tight tolerances, ensuring the strongest, lightest, and most technologically advanced rings available. These rings incorporate the same horsepower-producing piston ring technology trusted by top engine builders in prestigious racing series like Cup, IRL, NHRA, IHRA, and Formula 1. They are engineered to improve the efficiency and durability of engines, from extreme horsepower race applications to powerful industrial stationary engines. The set includes a dry film cylinder wall lubricant, which provides essential lubrication during the critical break-in period, effectively preventing ring-related cylinder wall burnishing and glazing.
