Total Seal T0190 40 Ductile Moly Gapless 2nd Piston Ring Kit

Total Seal Piston Rings - Ductile Moly Gapless 2nd Ring Set is designed to improve piston-to-cylinder sealing by utilizing Total Seal's patented Gapless® second ring technology. Unlike conventional rings that allow increasing blow-by as the ring gap wears, the Gapless® design uses an interlocking second ring assembly to maintain a more effective seal throughout the engine's service life. This helps reduce combustion gas leakage, improve oil control, and support more consistent engine performance.

Built with a ductile iron and moly-faced construction, these rings are well-suited for high-performance street and racing applications. The Gapless® second ring design is particularly beneficial for turbocharged, supercharged, and horizontally opposed engines, where improved oil control and blow-by reduction are critical. Total Seal's technology is widely used across motorsports, including drag racing, circle track, road racing, and other high-performance applications.
