Piston Ring Set 4.310 5/64 5/64 3/16

The Piston Ring Set 4.310 5/64 5/64 3/16 by Hastings is an essential engine rebuild component engineered for builders and mechanics who demand OEM-quality compression and oil control. This ring set serves as the critical sealing interface between piston and cylinder wall, maintaining combustion pressure while regulating oil film thickness—a function that directly impacts horsepower retention, fuel economy, and engine longevity. Whether you're performing a full rebuild on a performance engine or restoring a classic, a quality piston ring set is non-negotiable for reliable power delivery and extended engine life.

This set features a 4.310-inch bore diameter with precisely engineered ring dimensions: two compression rings at 5/64-inch thickness and an oil control ring at 3/16-inch thickness. The 5/64-inch compression rings are sized to maximize sealed volume while minimizing blowby, while the thicker 3/16-inch oil ring manages crankcase ventilation and prevents excess oil from entering the combustion chamber. Hastings piston rings are manufactured to exacting tolerances using high-quality ductile iron with optimized face coatings, ensuring consistent ring gap closure, minimal wear, and dependable sealing across the full RPM range whether at idle or sustained load.

This piston ring set is ideal for small-block and mid-displacement engine applications requiring a 4.310-inch piston diameter. Mechanics and engine builders appreciate Hastings rings for their stock-replacement quality at a fair price point, making them suitable for street engines, light performance builds, and restoration work where durability and value align. Installation requires proper ring gap spacing and careful honing to specification; follow OEM procedures and torque specs for the connecting rod during assembly to ensure optimal ring seating and longevity.
