Total Seal Ring Set, Classic Race, 3.935" Bore, (3.940" Ring) File Fit TSR-CR1005-65

Butler Performance uses Total Seal piston rings in most of our engines and assemblies. The main reason for this is their ability to build ring sets for us using rings from most of the major ring manufacturers as well as their own rings. This gives us a huge selection and Total Seal will custom build ring sets for almost any application if it's not an in-stock part. We offer Total Seal rings in several different styles: Classic Race (CR) sets are traditional, non- gapless sets using plasma-moly top rings. Gapless 2nd (T) sets use Total Seals original 2 piece gapless second rings, which provide less cylinder leakage over a longer period of time, especially popular when using alcohol. These may not be as suitable for some street applications. Gapless Top (M) sets use a 2 piece gapless top ring. These are the latest design by Total Seal and were made possible by the better ring materials developed over the last few years. The top gapless sets are designed to prevent trapping pressure between the top and second rings. We also offer TNT, stainless, dykes, and diamond lapped sets from Total Seal. If you don't see what you need, contact us and we can get it for you. Any of these upgraded sets can be added to our rotating assembly or engine combos.
