Piston Ring Set 4.040 Clsic Gold 1.5 1.5 3.0mm

The Piston Ring Set 4.040 Classic Gold 1.5 1.5 3.0mm from TOTAL SEAL is engineered for serious engine builders and high-performance mechanics who demand precision ring packages. This piston ring set is ideal for classic race applications where builders can dial in exact clearances and achieve optimal compression while minimizing blow-by.

Constructed from ductile iron with plasma moly coating, the Classic Gold ring design provides superior ring-to-bore stability and reduced friction compared to standard cast iron rings. The 1.5mm top ring, 1.5mm second ring, and 3.0mm oil control ring geometry is specifically tuned for 4.040-inch bore engines, with file-fit construction allowing you to hand-fit each ring to its specific cylinder for tight tolerances that maximize power transfer and minimize combustion gas escape.

This ring set is particularly beneficial for those assembling period-correct muscle car engines, vintage drag racing powerplants, or street performance builds. The low-tension design reduces parasitic drag, freeing up additional horsepower while maintaining effective sealing across a wide operating range, making it a reliable choice for high-performance applications.
