Piston Ring Set 4.135 Classic 1/16 1/16 3/16

The Piston Ring Set 4.135 Classic 1/16 1/16 3/16 from TOTAL SEAL is engineered for high-performance engine rebuilds and restorations where precision ring geometry directly impacts compression, blow-by control, and longevity. Designed for 4.135-inch bore engines, this classic ring set addresses the critical seal between piston and cylinder wall—the foundation of efficient combustion and oil management. Whether you're restoring a vintage engine, building a stroker platform, or upgrading worn compression rings, this TOTAL SEAL offering delivers the dimensional accuracy and material quality that serious engine builders and mechanics demand.

TOTAL SEAL's ring geometry—featuring 1/16-inch top and second ring thicknesses with a 3/16-inch oil ring thickness—is optimized for classic engine configurations where balance between sealing performance and friction is essential. The 1/16-inch compression rings provide superior gas sealing and faster ring seating during break-in, while the 3/16-inch oil control ring efficiently scrapes excess lubricant and returns it to the sump, maintaining proper oil film thickness on cylinder walls. Premium iron composition and precision manufacturing ensure consistent gap closure and reduced blow-by, translating to stable compression ratios and cleaner emissions in both street and vintage race applications.

This ring set is ideal for engine builders restoring displacement-specific small-block platforms, classic American V8s, and inline powerplants with 4.135-inch bore specifications. Proper installation requires careful bore measurement, ring gap setting, and piston groove cleaning to maximize ring life and sealing effectiveness. Always verify your engine's exact bore diameter and ring groove specifications before installation; even minor variances can affect ring performance and engine reliability during initial run-in and sustained operation.
