Common questions
How many pistons does one set of these rings cover?
One set of these Hastings Mfg piston rings is designed to cover two pistons. However, for Twin Cam 113" and Sportster 883 XL models, rings are sold per cylinder, so you would need to order two sets.
Are these piston rings compatible with Screaming Eagle pistons?
Yes, these Hastings Mfg piston rings are specifically designed to work seamlessly with both OEM (Original Equipment Manufacturer) and Screaming Eagle aftermarket pistons.
What is the main difference between Cast and Moly piston rings?
Moly-faced rings, like these, incorporate a molybdenum coating that provides a lower friction surface, leading to better wear resistance and a faster break-in period compared to traditional cast iron rings.
