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. Features Ideal for naturally aspirated, forced induction, or mild nitrous (hot street, drag & road race, circle & dirt track, tractor pull) Top Ring: Moly Max ductile Second Ring: Gapless Oil Ring: Standard tension Increased horsepower and wider torque curve 3" more engine vacuum Better oil control Sold in sets of 8 unless otherwise noted
