AS Piston Ring Set 4.005 2.0 1.5 4.0mm

The AS Piston Ring Set 4.005 by TOTAL SEAL is designed for engine builders and mechanics who require precision ring sets for high-performance and rebuilt engines. This set is essential for those restoring classic engines or upgrading cylinder work, ensuring reliability and compression integrity.

Featuring a 2.0mm top ring, 1.5mm second ring, and 4.0mm oil control ring, this three-piece configuration is engineered to fit a 4.005-inch bore. The advanced materials and precise groove tolerances minimize blowby and maximize oil control, critical for maintaining cylinder pressure and preventing oil consumption in freshly bored or honed cylinders.

This ring set is particularly beneficial for rebuild shops and vintage car restorers, providing the necessary components for a successful engine rebuild. Its design ensures consistent contact with the cylinder wall across various RPM ranges, making it suitable for both street and racing applications.
