Get Your Gap Right — Piston Ring Gap Explored

This means that once installed, they’re good to go. When fitting an aftermarket forged piston, however, you will most likely be working with ‘file-fit’ piston rings. In this article, we’re going to explore how to select, measure, and adjust your ring end gaps to help achieve a reliable ring seal.
