Piston Ring Set 4.560 Gapls 2nd 1/16 1/16 3/16

The TOTAL SEAL Piston Ring Set 4.560 Gapless 2nd 1/16 1/16 3/16 is engineered for serious engine builders and performance mechanics who demand precision ring sealing in high-displacement or bored-over applications. This piston ring set is designed for engines with a 4.560-inch bore diameter, making it essential for big-block rebuilds, stroker kits, and custom engine platforms where OEM rings fall short. Whether you're assembling a freshly bored block or restoring a vintage engine to modern performance standards, quality ring sets directly impact compression, blow-by control, and long-term durability.

TOTAL SEAL has engineered this four-ring package with gapless top-ring technology, which eliminates the gap overlap issue that can compromise seal integrity at extreme RPM or boost levels. The ring configuration—2nd ring at 1/16 inch, dual 1/16-inch intermediate rings, and 3/16-inch oil ring—provides optimal gas sealing and oil control across the full power band. The gapless design reduces friction losses while maintaining consistent side clearance, critical for engines operating at elevated boost pressure or in extended high-RPM environments. These rings are manufactured to exacting tolerances and material specifications that enable them to handle extreme combustion temperatures and cylinder pressures.

Engine builders rebuilding 4.560-bore platforms—including late-model big-blocks, LS variants, and custom displacement engines—will find this ring set indispensable for achieving reliable compression and minimizing blow-by in both naturally aspirated and forced-induction applications. The 1/16-inch and 3/16-inch ring thickness specifications are standard for larger-bore engines where ring strength and thermal stability matter most. Proper installation with correct ring end gaps, appropriate honing finish, and precise piston-to-wall clearance will maximize ring life and seal performance. This product is for experienced builders and shops prepared to follow TOTAL SEAL's installation guidelines and maintain strict tolerances during assembly.
