1 top ring. molybdenum filled iron top ring or a plasma moly ductile iron ring some that come pre lapped .or just plane iron ring thats phosphate coated will be black in color .some rings are chrome 1# ring a 2# that are pre lapped like grant rings .most all moly ring sets use a 2# ring that a torsional twist phosphated coated gray iron or ductile iron not chrome .the oil ring 3 pc can have the chrome oil rails pre lapped or stainless steel .so were did the chrome moly ring set come from? should be more like moly chrome that would state a top moly ring . 2#iron and 3# oil pc chrome pre lapped ring but not many say it that way . most all builds would never need the use of chrome rings most all engines i build use a moly face top ring been building them this way for 30 years i see not much need for a chrome top ring.chrome they say has come a long way from the good old day were guys would do things to try to get them to seat . if your other rings are a hasting moly top ring or others you will see the moly filler gray in color with dark gray out lines on the ring face. the ring on a plasma spray moly top ring it will look even and some over all gray on the face will look some what sliver no ring part numbers ?Last edited by pat mccarthy; 09-17-2009 at 06:21 PM.
