Total Seal Classic Race Piston Ring sets are a prefered 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 3 Piece Standard 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. Gas-Ported piston rings feature strategically sized and placed horizontal slots in the ring allowing combustion gas to enter through the groove and behind the ring to gasload the ring providing greatly improved ring sealing. The primary job of the piston ring is to create the seal between the piston and the cylinder wall. Total Seal 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. Total Seal concentrates on making the most precise, strongest, lightest and innovative piston rings available. From extreme horsepower race engines to powerful stationary engines for industrial use and everything in between, Total Seal can help you improve the efficiency and durability of your engine.
