Piston Ring Set 4.130 Gapls 2nd 1/16 1/16 3/16

The Piston Ring Set 4.130 Gapls 2nd 1/16 1/16 3/16 by TOTAL SEAL is engineered for serious engine builders and high-performance mechanics who demand precision ring geometry and reliability in modified or racing applications. This complete ring set addresses the critical gap tolerance specifications required for 4.130-inch bore engines, making it essential for custom short-block assemblies, stroker builds, and competition powerplants where standard OEM rings fall short of performance requirements.

Total Seal's gapless (Gapls) top compression ring technology eliminates the traditional end gap, reducing blowby and improving combustion pressure retention—a critical advantage in forced-induction and high-RPM scenarios. The second ring configuration of 1/16-inch combined with the 3/16-inch oil control ring provides optimized scraping action and oil film management across the cylinder wall, while the precision gapless design minimizes carbon buildup and extends ring life under sustained load. Each ring in this set is manufactured to exacting tolerances and finished to work seamlessly with honed cylinder walls and modern piston designs.

Professional engine builders, drag racing teams, and street performance enthusiasts benefit most from this ring set when assembling 4.130-inch bore displacement engines for maximum power output and durability. Proper cylinder wall preparation, correct installation with ring compressors, and verification of end-gap clearance on the top ring are essential during assembly. Compatibility depends on piston design and bore specifications—verify your block and piston combination matches the 4.130-inch bore diameter before purchase to ensure optimal sealing and performance.
