Perf. Piston Ring Set V8 4.120 Bore 1.5x1.5x3.0

The Perf. Piston Ring Set V8 4.120 Bore 1.5x1.5x3.0 from NPR Piston Rings is designed for high-performance V8 engines with a 4.120-inch bore specification. This set is crucial for enhancing engine compression, controlling blow-by, and managing oil in various applications, including street performance builds and race engines. Whether you're refreshing a factory engine or building a custom performance engine, these piston rings are essential for achieving optimal performance.

Featuring a configuration of a 1.5mm top ring, 1.5mm second ring, and 3.0mm oil control ring, this piston ring set is optimized for durability and performance across a wide RPM range. The design ensures superior sealing geometry, which minimizes friction and blow-by leakage, making it suitable for both naturally aspirated and forced-induction applications. NPR's stringent manufacturing standards guarantee tight tolerances and consistent ring end-gaps, which help reduce carbon buildup and extend the lifespan of the rings.

Performance enthusiasts, engine rebuilders, and mechanics will find this ring set particularly beneficial for its precise fitment and reliable sealing. The 4.120-inch bore specification is compatible with a variety of popular V8 platforms, including small-block Chevys, Fords, and Chryslers, as well as custom bored applications in the performance community. This versatility makes it a valuable addition to any engine rebuild or performance upgrade project.
