The Perf. Piston Ring Set V8 4.055 Bore 1.2x1.2x3.0 from NPR Piston Rings is an essential component for V8 engine builders and performance mechanics. Designed for applications requiring precise bore sizing and optimized ring geometry, this set is ideal for high-performance street or competition engines. It is particularly beneficial for those undertaking stroker builds or overbore configurations.
This three-piece NPR ring set features a 1.2mm top ring, a 1.2mm second ring, and a 3.0mm oil ring, which effectively balances compression sealing with oil control for a 4.055-inch bore diameter. The modern 1.2mm thickness of the top and second rings reduces friction compared to older designs while ensuring a superior fit and dynamic sealing across the engine's RPM range. NPR's rigorous manufacturing standards guarantee consistent tension and proper end-gap clearance.
Engine builders and mechanics trust NPR piston rings for rebuilds and performance projects requiring high-quality components. This piston ring set is suitable for various V8 gasoline engines, ensuring proper ring seal and minimal blowby, which contributes to extended engine longevity under demanding conditions.
