Ensuring Correct Fitment
This set is specifically for Twin Cam 1852 engines with a .005 oversize bore. For most Twin Cam applications, one set will cover both pistons. However, if you are working on a TC 113" or 883 XL model, you will need to order two sets as these rings are sold per cylinder for those specific engine sizes. Always confirm your engine's bore size before ordering to ensure proper fitment.

Common questions
Are these rings for both cylinders or just one?
For most Twin Cam 1852 cc engines, one set covers both pistons. However, TC 113" and 883 XL models require two sets per bike, as one set covers one cylinder.
Will these work with Screaming Eagle pistons?
Yes, these Hastings Mfg piston rings are designed to be fully compatible with both OEM and Screaming Eagle pistons.
What does .005 oversized mean?
.005 oversized rings are for cylinders that have been bored .005 inches larger than the standard bore. This is a common practice during engine rebuilding to create a fresh, true cylinder surface.
