The Piston Ring Set 4.466 Classic 2.0 1.5 4.0mm from TOTAL SEAL is designed for engine builders and performance enthusiasts who require reliable ring seal in classic and street applications. This premium ring set is essential for maintaining optimal compression and controlling blowby across the piston face while minimizing friction and oil consumption.

Featuring a 4.466-inch bore diameter, this ring set includes a classic three-ring package: a 2.0mm top compression ring, a 1.5mm second ring, and a 4.0mm oil ring. This configuration is proven to deliver balanced performance across various RPM ranges, with the oil ring providing effective oil control without excessive drag. TOTAL SEAL's engineering optimizes ring gaps and tensions for both cast-iron and aluminum cylinder walls, which helps reduce wear and extend engine life.

This piston ring set is particularly beneficial for small-block engine rebuilds and vintage muscle car restorations, ensuring compatibility with engines in the 4.45- to 4.50-inch bore range. Proper installation is crucial, and users should verify ring gap settings to match their specific cylinder wall finish for optimal performance.
