Total Seal has just announced all new piston ring sets that feature 1.1 mm (0.043 inch), 1.1 mm, 2.0 mm thicknesses for most bore sizes ranging from 4.000 bores all the way up to 4.250. These packs feature the AP steel top ring, ductile iron Napier second rings (in most sets where available) and a new oil ring set.

Oil rings will be available in standard low- and high-tension configurations. These sets will feature shallow radial depths: tops: .134”, 2nds: .145″, oils .130″ ( 1.1mm, 1.1mm and 2mm). This combination dramatically reduces friction and significantly increases bore conformability. The AP steel top ring features the C-33 PVD coating, applied using vacuum deposition that won’t flake or chip off; while the ductile iron Napier 2nd rings offer increases durability and improves oil control. These new sets are available in gapless and conventional styles.

Total Seal’s new ring packs are suitable for normally aspirated as well as turbo, forced induction and nitrous applications. The reduced stack height of these rings permits the use of a piston with a very short compression height allowing the use of longer connecting rods and/or increased stroke while keeping the wrist pin out of the oil ring groove.
