The NPR Perf. Piston Ring Set V8 4.145 Bore 1.5x1.5x3.0 is designed for high-performance V8 engines that demand precision and reliability. This piston ring set is essential for controlling blowby, maintaining compression, and regulating oil consumption, making it ideal for engine builders and mechanics involved in rebuilding or upgrading V8 platforms.
Engineered with a 1.5mm top ring, 1.5mm second ring, and 3.0mm oil control ring configuration, this set is proven effective across various V8 combinations. The 4.145-inch bore specification ensures a precise fit, minimizing radial clearance issues that could compromise sealing.
