Total Seal Classic Race Gas-Ported Piston Rings

Extensively tested and proven, new ring design delivers the benefits of gas-ported performance without gas-ported pistons. Ductile iron, plasma moly top rings feature strategically sized and placed horizontal slots that allow combustion gases to enter through the groove and behind the ring, gas-loading the ring for improved sealing. File-fit sets also include cast tapered-face second rings and standard-tension oil rings.
