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.

• Gas-ported performance without gas-ported pistons

• 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. When ordering simply ask for Gas-Ported on your top ring sets.
