Piston Ring Set 4.030 TNT 1/16 1/16 3/16

The Piston Ring Set 4.030 TNT 1/16 1/16 3/16 by TOTAL SEAL is engineered for high-performance engine rebuilds and racing applications requiring precision ring dynamics. This eight-cylinder piston ring kit addresses the critical need for controlled compression and oil management in engines operating under elevated RPM and load conditions. TNT formulations deliver the thermal stability and wear resistance necessary for both street and competition use, making this set ideal for engine builders and enthusiasts rebuilding or upgrading displacement-specific powerplants.

This ring set features a 4.030-inch bore specification with a three-piece design: 1/16-inch top ring, 1/16-inch second ring, and 3/16-inch oil ring, all manufactured from ductile iron and finished with a phosphate coating for reduced friction and extended ring life. The file-fit design demands careful honing to exact bore diameter, ensuring proper ring seating and preventing blow-by across the piston face. Standard tension characteristics maintain consistent oil film thickness while minimizing parasitic drag, a critical balance in high-output engines where ring blow-by directly impacts seal integrity and fuel economy.

Builders restoring small-block or medium-block V8 engines to 4.030-inch bore will find this kit indispensable for maintaining OEM-equivalent or enhanced ring seal quality. Installation requires precision honing and careful gap-setting during assembly; improper bore preparation or ring installation will compromise compression and durability.
