Piston Ring Set CS 4.605 Bore 1.5 1.5 3.0

The Piston Ring Set CS 4.605 Bore 1.5 1.5 3.0 by Total Seal is engineered for builders and mechanics who demand precision ring control and extended engine durability. This ring set addresses the core challenge every high-performance engine faces: maintaining proper ring tension, blow-by control, and oil management across varying RPM ranges and load conditions. Whether you're rebuilding a street engine, preparing a race motor, or restoring a classic, quality piston rings are non-negotiable for achieving reliable compression and minimizing ring flutter.

Total Seal's CS series features a 4.605-inch bore specification with a precisely calibrated ring package: 1.5-mm top ring, 1.5-mm second ring, and 3.0-mm oil ring. This configuration balances low-friction performance with robust sealing geometry, allowing rings to follow bore wall irregularities while maintaining consistent pressure across the ring face. The 1.5-mm compression ring design reduces reciprocating mass and promotes faster ring response, critical for engines with aggressive cam profiles or high valve overlap. Total Seal's manufacturing tolerances and material composition ensure minimal wear rates and stable ring gap clearances throughout the engine's service life, even under boost or extended high-load operation.

This piston ring set suits engine builders, restoration shops, and serious enthusiasts rebuilding motors in the 4.605-inch bore range. Proper installation requires careful ring gap setting to specification—measuring each ring individually and filing or honing as needed for your exact bore diameter and intended application. Always verify bore diameter, piston dome height, and ring land depth before ordering; even slight deviations demand custom gap calculations. Pair these rings with quality pistons, properly finished bores, and correct ring installation tools to unlock their sealing potential and achieve the compression ratio and blow-by control your rebuilt engine demands.
