.080 Oversize. These have the parkerized top ring. Superior is a quality set of rings made for Dixie Distributing by TRW and they have been stored in warehouse settings for many years.  We have opened many sets of these to inspect and have noticed that some (not all) of the oil spacer expanders have some minor rust spotting in some places and will need a little cleaning. What we found we tried to illustrate in the pics. The rings look fine. Some of the rings (not all) are slightly stuck together from dried oil residue from years of sitting and can be gently pulled apart. They will need to be wiped down with a cleaner but should be an easy clean. These rings are new and we will guarantee all the rings to be completely useable. Please understand that when buying these rings. Please ask questions for any specific concerns.
