Total Seal S4194 TSS Street Gapless Piston Ring Set 4.016" Bore 6-Cylinder

The Total Seal S4194 TSS Street Piston Ring Set delivers superior cylinder sealing performance through proven gapless second ring technology. Designed for 6-cylinder applications with a 4.016 inch (102.006mm) bore, this complete ring set helps eliminate power-robbing blowby and maintains consistent compression for optimal engine performance.

Gapless Second Ring Technology:

Total Seal's patented gapless design features an oversize cast iron main ring combined with a chrome-faced secondary ring that overlaps the main ring's end gap. This interlocking arrangement creates a virtually gapless seal, achieving a leakdown rate of just 2 percent or less compared to 8-10 percent for conventional gapped rings. The result is improved horsepower retention, better oil control, and reduced combustion gas migration into the crankcase.

Ring Specifications:

• Top ring: 3.0mm thickness, cast iron construction with cast iron facing
• Second ring: 2.35mm thickness, cast iron with gapless design
• Oil ring: 4.0mm thickness, stainless steel construction with standard tension
• Bore size: 4.016 inches (102.006mm)
• File fit: No
• Gas ported: No

Applications:

Ideal for street performance and mild racing applications with compression ratios of 10.5:1 or lower. This ring set is commonly used in diesel applications including the Dodge/RAM 5.9L Cummins engine (1988-2008), though fitment should always be verified for your specific build. Sold as a complete set for one 6-cylinder engine.

Total Seal's TSS Street rings provide the durability needed for daily driving while offering the performance advantages that racers demand, making them an excellent choice for engine rebuilds and performance upgrades.
