The Total Seal TS1 Street/Race Gapless 2nd Piston Ring Set, T7190 35, is designed for optimal engine efficiency and durability in both extreme horsepower race engines and powerful industrial applications. This 8-cylinder set features a bore size of 4.263+5 and a ring configuration of 1/16 inch for the top ring, 1/16 inch for the second ring (Gapless), and 3/16 inch for the oil ring. Total Seal is known for making precise, strong, light, and innovative piston rings. The set includes a dry film cylinder wall lubricant to ensure proper lubrication during the critical break-in period, effectively eliminating ring-related cylinder wall burnishing and glazing. Independent dyno tests have shown that Total Seal Gapless 2nd Ring sets deliver significant net increases in both horsepower and torque over conventional rings.
