Total Seal Gapless TSS Street 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. Features Ideal for naturally aspirated street and mild race (no forced induction or nitrous) Top Ring: Cast iron Second Ring: Gapless Oil Ring: Standard tension For 10.5:1 or lower compression ratio Increased horsepower and wider torque curve More engine vacuum Better oil control All rings sold in sets of 8 unless otherwise noted
