Installation Notes and Compatibility
This set is designed for standard bore Twin Cam 1800 engines. Most Twin Cam 1800 applications will use one set for both pistons. However, riders with TC 113" and 883 XL models will need to order two sets as they are sold per cylinder for those specific applications. Always confirm your engine's bore size before ordering.

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.
