Total Seal T0390 65 Ductile Moly Gapless 2nd Piston Ring Kit

Total Seal Piston Rings - Ductile Moly Gapless 2nd Ring Set is engineered to provide superior sealing performance through Total Seal's patented Gapless® second ring technology. Unlike conventional piston rings that allow combustion gases to escape through the ring end gap, the Gapless® design utilizes an interlocking secondary rail that significantly reduces blow-by and helps maintain cylinder pressure. The result is improved engine efficiency, more consistent performance, and enhanced long-term sealing capability.

Constructed from durable ductile iron with a moly-faced sealing surface, this ring set is designed to withstand the rigors of high-performance street and racing environments. Improved cylinder sealing supports increased horsepower and torque, greater engine vacuum, cleaner engine oil, and enhanced oil control. Total Seal recommends Gapless® second rings for turbocharged and supercharged applications where minimizing blow-by and maximizing sealing efficiency are critical to performance and reliability.

• Patented Gapless® 2nd ring technology dramatically reduces blow-by for improved cylinder sealing
• Durable ductile moly construction provides excellent wear resistance and long service life
• Helps increase horsepower and torque by retaining more combustion pressure within the cylinder
• Improves oil control and helps keep engine oil cleaner by reducing crankcase contamination
• Ideal for naturally aspirated, turbocharged, supercharged, and mild nitrous engine combinations
