Perf. Piston Ring Set V8 4.070 Bore 1.5x1.5x3.0

Overview

The Performance Piston Ring Set V8 4.070 Bore 1.5x1.5x3.0 from NPR Piston Rings is engineered for serious engine builders and automotive enthusiasts requiring reliable compression sealing in big-block and stroker V8 applications. This precision ring set is well-suited for rebuilding classic muscle engines, restoring high-displacement platforms, and completing custom builds. Featuring a 1.5mm top ring, a 1.5mm second ring, and a 3.0mm oil ring stack, this set balances effective oil control with robust resistance to ring flutter. The 4.070-inch bore size is tailored specifically for large-displacement V8 engines to ensure optimal performance across the RPM range. Built to strict manufacturing tolerances, each ring properly seats against the piston groove to prevent micro-welding during high-load operations, while the three-piece oil ring design maintains peak pressure sealing throughout the combustion cycle.
