Piston Ring Set 4.155 Clsic Gold 1.5 1.5 3.0mm

The Piston Ring Set 4.155 Classic Gold 1.5 1.5 3.0mm from Total Seal is engineered for high-performance and classic race applications where precision ring fitment directly impacts engine efficiency and longevity. This file-fit ring set is designed for 8-cylinder engines with a 4.155-inch bore diameter, making it ideal for street performance builds, vintage racing engines, and precision engine rebuilds where low-tension ring dynamics are required. Whether you're restoring a classic muscle car engine or optimizing a competition powerplant, Total Seal's reputation for race-proven durability makes this ring set a trusted choice among serious engine builders and performance enthusiasts.

This piston ring set features a 1.5mm top ring, 1.5mm second ring, and 3.0mm oil control ring configuration optimized for low-tension operation, which reduces parasitic drag and improves horsepower delivery while maintaining reliable oil control and blowby management. The rings are manufactured from ductile iron with plasma moly coating on the bearing surfaces, providing superior corrosion resistance and extended ring life across varying operating temperatures and fuel conditions. File-fit construction means precision honing and fitting during installation is required, but the payoff is superior ring seal and reduced blowby that translates to cleaner combustion and better cylinder pressure retention throughout the rev range.

Engine builders and mechanics rebuilding 4.155-inch bore eight-cylinder engines benefit most from this ring set's proven performance characteristics, particularly in applications where low-tension operation and precise bore matching deliver measurable gains in throttle response and fuel economy. Installation requires precision boring and honing to Total Seal specifications, along with careful ring end-gap filing to match your exact bore dimensions and operating parameters. Compatible with both carbureted and fuel-injected platforms, these rings deliver consistent performance across street, strip, and vintage racing environments where reliability and power output matter equally.
