Gaps open as standard piston rings wear, allowing more combustion gases to escape (blow-by). Total Seal 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 giving you better over all performance that lasts.

Gives You Increased Horsepower & a Wider Torque Curve
