Pair of .020 over size low compression pistons for Harley-Davidson 1200cc/ 74-in Big Twins. We bought a large box of these and are selling two pistons per listing. No rings or circlips. That's enough to do one engine. Part number is J-11228L .020. You can see that they are over size from the labeling on the box. If you purchase one listing you will get one pair of pistons which is enough to do one engine. Please note that this has been sitting in a warehouse for decades so there might be some minor cleanup needing to be done before installing. Boxes are in rough shape.
