Perf. Piston Ring Set V8 4.135 Bore 1.2x1.2x3.0

The Perf. Piston Ring Set V8 4.135 Bore 1.2x1.2x3.0 is an essential component for engine builders and performance mechanics focused on enhancing engine efficiency. This piston ring set is specifically designed for large-displacement V8 engines with a 4.135-inch bore diameter, making it ideal for high-performance rebuilds, restorations, or upgrades.

Featuring a 1.2x1.2x3.0mm ring profile, this set balances top-ring tension for optimal gas sealing while ensuring effective oil scraping. The 1.2mm thickness of the top and second rings helps control blow-by and reduce friction losses, which is crucial for both naturally aspirated and forced-induction applications. The 3.0mm oil ring design promotes efficient crankcase ventilation and maintains a consistent lubrication film during high-rpm operation.

This piston ring set is perfect for experienced engine builders, restoration shops, and performance mechanics who demand precision and reliability in their engine components. With NPR's commitment to quality manufacturing, these rings ensure tight tolerances and prevent excessive gap variation, which can lead to increased parasitic losses and reduced engine performance.
