The Perf. Piston Ring Set V8 4.140 Bore 1.5x1.5x3.0 from NPR PISTON RINGS is designed for high-performance V8 engines, where precise ring fitment is crucial for optimal compression, blow-by control, and durability. This set is ideal for engine builders working on stroker motors, vintage big-blocks, or those upgrading existing engine platforms.
Featuring a 1.5mm top ring, 1.5mm second ring, and 3.0mm oil ring configuration, this piston ring set is engineered to perform under high RPM and boosted conditions. The rings are precision-manufactured from high-grade cast iron with modern face coatings, ensuring minimal friction and superior sealing to prevent excessive wear on cylinder walls.
This ring set is compatible with commonly bored small-block platforms such as the 350, 383, 406, and 427, as well as select big-block engines. Mechanics and engine builders trust NPR for both stock restorations and performance rebuilds, where matching OEM specifications is essential.
