Total Seal Gapless TS1 Race Piston Rings

Product images may differ from actual product appearance.

Gaps open as standard piston rings wear, allowing more combustion gases to escape (blow-by). Gapless rings solve this problem with two-part interlocking rings to close gaps and to improve piston-cylinder seals. As gapless rings wear, gaps stay sealed.
