Perf. Piston Ring Set V8 4.160 Bore 1.2x1.2x3.0

The Perf. Piston Ring Set V8 4.160 Bore 1.2x1.2x3.0 is a precision-engineered ring set designed for serious V8 engine builders and performance mechanics who demand OEM-quality compression and oil control. This set is ideal for those working on stroker, overbore, or high-performance rebuilds, ensuring optimal sealing of combustion pressure while effectively managing oil consumption.

Featuring a 1.2mm top ring, 1.2mm second ring, and 3.0mm oil ring configuration, this set is specifically engineered for V8 applications requiring a 4.160-inch bore diameter. The design ensures optimal gas sealing in the combustion chamber while the oil control ring manages lubrication under high RPM and boost conditions. NPR's manufacturing process guarantees consistent ring gap clearances and ideal radial tension to minimize blow-by.

This ring set is perfect for V8 engine builders working with small-block or performance platform builds, including custom stroker assemblies. Proper piston ring selection is crucial for enhancing power delivery, fuel economy, and long-term engine durability, making this set a valuable addition to any performance engine project.
