3 Before you start gapping your new rings, take a moment to make sure they are properly matched for the pistons you will be using. The rings should slide easily into the appropriate ring land but still have a tight fit. The radial thickness (the distance from the inside to the outside edges) should be matched to the depth of the land so that the entire ring will slide into the groove, but the land should be so deep that it absolutely swallows the ring with room to spare. Inserting the ring into the land backward like you see here is an easy and quick way to check proper fitment. View Related Article
