CS Piston Ring Set 4.500 Bore .043 .043 3/16

The CS Piston Ring Set 4.500 Bore .043 .043 3/16 from Total Seal is engineered for serious engine builders and performance mechanics who demand precision ring geometry and consistent compression in high-revving or modified applications. A quality piston ring set forms the critical seal between your piston and cylinder wall, controlling blow-by, regulating oil consumption, and maintaining combustion pressure under load. This particular set is designed for engines with a 4.500-inch bore diameter, making it ideal for big-block rebuilds, racing engines, or custom performance builds where OEM rings fall short of durability and sealing requirements.

Total Seal's CS ring set features dual .043-inch compression ring thicknesses and a .3/16-inch oil control ring configuration, optimized for balanced blow-by reduction and precise oil film management across the piston stroke. The .043-inch compression ring width delivers superior sealing characteristics and reduced friction compared to thicker designs, while the 3/16-inch oil ring effectively scrapes excess lubricant from the cylinder wall without compromising ring durability or causing scuffing. This multi-ring architecture is particularly valuable in performance applications where higher combustion temperatures and cylinder pressures demand reliable sealing, and where ring flex and conformability directly impact horsepower retention and engine longevity.

These rings suit rebuilders working on 4.500-bore big-block Chevys, Fords, and Chryslers, as well as stroker builds and displacement-increase projects that require custom ring specifications. Installation requires precise ring gap setting and proper ring groove fit during final honing—critical steps that ensure the CS Piston Ring Set 4.500 Bore .043 .043 3/16 performs as designed. Mechanics and engine shops familiar with Total Seal's reputation for precision manufacturing and comprehensive ring solutions will find this set delivers the sealing integrity and durability expected in both naturally aspirated and forced-induction platforms.
