Piston Ring Set 4.155 Classic 043 043 3.0mm

The Total Seal Piston Ring Set 4.155 Classic 043 043 3.0mm (SKU TOTCS9010-35) is a precision-engineered ring kit designed for eight-cylinder engines requiring file-fit installation and advanced ring profiling. This classic steel piston ring set delivers optimized sealing geometry and low-tension characteristics ideal for applications where ring flutter resistance and controlled blow-by are critical performance factors.

The 4.155-inch bore specification accommodates a wide range of displacement and stroker configurations in traditional and modern engine builds. The 0.043-inch x 0.043-inch x 3.0mm ring thickness provides balanced radial pressure without excessive tension that can increase friction losses or accelerate bore wear. Total Seal's chromium nitride coating on the steel construction enhances ring life by reducing scuffing and improving corrosion resistance, particularly valuable in high-humidity storage or engine environments exposed to moisture. File-fit design requires careful honing to specification for optimal ring-to-groove clearance and sealing performance—a standard practice among builders who prioritize precision ring seating and minimal blow-by.

This ring kit is specified for serious engine builders, restoration shops, and enthusiasts rebuilding eight-cylinder powerplants where OEM or equivalent ring quality is essential. Whether for naturally aspirated, supercharged, or turbocharged applications, the low-tension profile minimizes parasitic drag while maintaining adequate sealing for modern fuel injection and emissions systems. Compatible across classic muscle cars, hot rods, marine engines, and performance street engines where proven ring technology delivers reliable compression retention and minimal oil consumption over extended service intervals.
