Piston Ring Set 4.290 1/16 1/16 3/16

The Piston Ring Set 4.290 1/16 1/16 3/16 from Hastings is a precision-engineered component designed for engine rebuilds and high-performance applications where OEM reliability meets competitive pricing. This set is ideal for restoring classic engines, completing full bottom-end overhauls, or replacing worn compression and oil control rings.

This piston ring set features a 4.290-inch bore diameter with a precisely calculated ring geometry: two 1/16-inch top and second compression rings, and a 3/16-inch oil control ring. The dual compression rings work together to seal combustion pressure while minimizing blow-by, which is critical for maintaining cylinder pressure and engine efficiency. The oil control ring helps prevent excessive oil consumption by maintaining a controlled film on cylinder walls.

Mechanics and engine builders choose this piston ring set for engines requiring a 4.290-inch bore—common in mid-displacement street engines, light truck platforms, and vintage automotive rebuilds. Hastings has been a trusted name in piston ring manufacturing for decades, ensuring that their rings maintain proper cylinder wall contact across full RPM ranges and operating temperatures.
