Description

Whether it's a car, truck, motorcycle, marine, or performance racing application—properly sealing the piston to the engine block is a requirement. Hastings premium ductile ring sets do just that, and they're offered in many different options to fit virtually any piston. If the engine you're working on is blowing smoke, using excessive oil, or at a loss for power, it may be time for new rings. These premium ductile piston ring sets are great for rebuilds or new builds, daily drivers or performance vehicles. Order the sizes needed for your project.
