Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only. If you’re unsure about what’s included with this product, please contact our team for clarification.

Whether it's a car, truck, motorcycle, marine, or performance racing—properly sealing the piston to the engine block is a requirement. Hastings Piston ring sets do just that, while being offered in many different options to fit virtually any piston out there. If the engine your working on is blowing smoke, using excessive oil, or at a loss for power, it may be time for new rings. Hasting piston ring sets are great for rebuilds or new builds. Hastings has been manufacturing piston rings since 1915 and they have not spent a second developing anything but piston rings. Trust the professionals at Hastings and use them on your next job.
