Common questions
Are these rings cast or moly?
These specific Hastings Mfg piston rings are made with a moly composition. Moly rings are known for lower friction and better high-RPM performance compared to cast rings.
Do I need one or two sets for my 883 XL or Twin Cam 113" engine?
For 883 XL and Twin Cam 113" models, you must order two sets per bike, as these rings are sold per cylinder for those specific applications, not per engine.
