Hastings MFG piston rings are engineered for precision fitment, offering compatibility with both OEM and Screaming Eagle pistons. Available in either Cast or Moly construction, these rings feature a three-piece oil ring design to ensure reliable performance. The components are manufactured in the USA, providing riders with a durable hard part solution for their engine builds.
These piston rings are sold in sets intended for two pistons, simplifying inventory management for standard applications. However, specific models including the TC 113" and 883 XL are packaged on a per-cylinder basis. For these particular applications, it is necessary to order two sets to complete a full bike installation, ensuring correct coverage for both cylinders.
