Total Seal Classic Race Piston Ring sets are a preferred choice for race engine builders. Total Seal Classic Race Piston Ring Sets feature a Ductile Iron Plasma Moly Top Ring, Reverse Tortional Taper Faced Conventional 2nd Ring, and a Low Tension Oil Ring. Total Seal Classic Race Piston Ring sets are designed for use in all applications including mild nitrous, boost, turbo, and forced induction applications. The primary job of the piston ring is to create the seal between the piston and the cylinder wall. Our new Gas-Ported piston rings represent an evolution in ring seal. The conventional practice of thick, heavy, high tension rings that fought against cylinder pressure to maintain seal has been revolutionized. Instead of fighting cylinder pressure, gas ported rings harness those forces and use them to improve ring seal. These advanced rings benefit all engines, especially turbocharged and supercharged engines. Features strategically sized and placed horizontal slots in the ring allowing combustion gas to enter through the groove and behind the ring to gas-load the ring providing greatly improved ring sealing. Extensively tested in virtually every form of engine with the same increases in ring sealing time after time. Applications are available in both steel and ductile iron for top ring placements.
