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 engine component designed for 8-cylinder applications requiring exact bore and ring thickness specifications. Piston rings are critical to engine performance, sealing the combustion chamber, controlling oil consumption, and maintaining compression during the engine's power stroke. This standard tension iron ring kit is engineered for engines with a 4.290-inch bore diameter and meets OEM specifications for reliable, long-term operation in both street and performance applications.

Each ring in this four-piece set features precise dimensional tolerances: 1/16-inch top and second ring thickness with a 3/16-inch oil ring thickness, all cast from durable iron to withstand extreme combustion temperatures and pressures. The standard tension design balances ring-to-wall contact for optimal sealing without excessive drag, reducing parasitic losses while maintaining effective oil control. Iron construction provides superior heat dissipation and longevity compared to alternative materials, making it ideal for high-mileage rebuilds, race applications, and heavy-duty engine work where reliability is non-negotiable.

This piston ring set is essential for anyone performing a complete engine rebuild, honing, or overhaul on 8-cylinder engines with the matching 4.290-inch bore specification. Proper ring installation requires careful measurement and gapping to match your specific engine's bore finish and operating conditions. The lightweight 1.1-pound kit is compact and easy to handle during assembly. Professional engine builders and serious enthusiasts rely on Hastings rings for consistent performance and durability across diverse engine platforms and power levels.
