Total Seal T3690 65 Ductile Moly Gapless 2nd Piston Ring Kit

Total Seal Piston Rings - Ductile Moly Gapless 2nd Ring Set is designed to maximize cylinder sealing efficiency with 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 uses an interlocking secondary rail to create a more complete seal. This significantly reduces blow-by, improves compression retention, and helps maintain consistent engine performance throughout the life of the engine.

Constructed from durable ductile iron with a moly-faced sealing surface, this ring set delivers the strength and wear resistance required for high-performance street, racing, turbocharged, and supercharged applications. Improved sealing helps increase horsepower and torque potential, enhance engine vacuum, promote cleaner oil, and improve overall oil control. Total Seal recommends Gapless® second rings for forced-induction applications where optimal cylinder pressure retention is essential for power and reliability.

• Patented Gapless® 2nd ring technology helps virtually eliminate blow-by for superior cylinder sealing
