Total Seal T3690 40 Ductile Moly Gapless 2nd Piston Ring Kit

Total Seal Piston Rings - Ductile Moly Gapless 2nd Ring Set is engineered to improve piston-to-cylinder sealing with Total Seal's patented Gapless® second ring technology. Unlike conventional ring designs that allow combustion gases to escape through the end gap, the Gapless® configuration uses an interlocking ring assembly to significantly reduce blow-by, helping maintain cylinder pressure and improve overall engine efficiency. This advanced sealing technology delivers consistent performance and long-term reliability in both street and racing applications.

Constructed from durable ductile iron and featuring a moly-faced ring surface, this ring set is designed to withstand the demands of high-performance engines. Enhanced sealing helps improve horsepower and torque potential, increase engine vacuum, reduce oil contamination, and provide better oil control. Total Seal recommends Gapless® second rings for turbocharged and supercharged applications where maximizing cylinder seal and minimizing blow-by are critical to performance and durability.

• Patented Gapless® 2nd ring technology helps virtually eliminate blow-by for improved cylinder sealing
• Ductile moly construction provides excellent durability, wear resistance, and long service life
• Helps increase horsepower and torque by retaining more combustion pressure within the cylinder
• Enhanced oil control helps reduce oil consumption and minimize crankcase contamination
• Ideal for naturally aspirated, turbocharged, supercharged, and mild nitrous performance applications
