The Total Seal Piston Ring Set 4.060 Gapless 2nd Ring (SKU TOTTG3690-65) is designed for high-performance engine builds that require precision bore fit and maximum compression control. This piston ring set is ideal for engine builders and performance enthusiasts working on naturally aspirated or turbocharged eight-cylinder engines.
Manufactured from ductile iron with a natural finish, this ring set features a gapless 2nd ring configuration, which helps maintain stable ring tension and seal integrity under high-RPM operation. The three-piece configuration includes a 1/16-inch top ring, a 1/16-inch second ring, and a 3/16-inch oil ring, providing the compression sealing and blow-by control that competitive builders demand.
Engine builders will appreciate the file-fit precision of these rings, which require hand-honing to the specific bore for optimal clearance. This manual fitting process ensures concentricity and prevents binding during operation, making it a reliable choice for those seeking peak horsepower output and ring seal reliability.
