About Hastings Mfg
Hastings has manufactured piston rings in the United States since 1915, supplying both the automotive and powersports rebuild markets. Rings are one of the few parts where a rebuild genuinely should not be cheapened.
These Hastings Mfg piston rings are crafted for Twin Cam 1800 engines, featuring a .005 oversize bore and moly coating. They deliver a robust ring seal and excellent oil control, essential for maintaining engine integrity and performance.
Why riders pick this
- Moly-coated for reduced friction and enhanced wear
- Three-piece oil ring design for superior oil control
- Compatible with OEM and Screaming Eagle pistons
- .005 oversize for bored cylinders
- Made in the USA for exceptional quality
For Twin Cam 1800 engines that have been bored .005 over stock, these Hastings Mfg moly piston rings are the ideal choice. They are engineered to provide a precise fit and reliable performance, crucial for any performance build or engine refresh.

Fitment Considerations for Your Build
This set is specifically for Twin Cam 1800 engines with a .005 oversize bore. Most Twin Cam 1800 applications will use one set for both pistons. However, if you're working on a TC 113" or 883 XL, you will need to order two sets as they are sold per cylinder for those specific applications. Always verify your engine's bore size before purchasing.

Will these work with aftermarket Screaming Eagle pistons?
Yes, these Hastings Mfg piston rings are specifically designed to be compatible with both OEM and Screaming Eagle pistons.
Do I need two sets for my Twin Cam 1800?
For most standard Twin Cam 1800 engines, one set is sufficient. However, TC 113" and 883 XL models require two sets, as they are sold per cylinder.

The rings themselves are awesome but the fact that they took nearly a week to ship even though they showed as in stock and I payed extra for next day air kinda sucked.
