Perf. Piston Ring Set V8 3.905 Bore 1.2x1.5x3.0

The Perf. Piston Ring Set V8 3.905 Bore 1.2x1.5x3.0 is designed for engine builders and performance enthusiasts who require precise ring fitment and reliable compression across all eight cylinders. This NPR piston ring set is specifically made for V8 engines with a 3.905-inch bore diameter, making it suitable for stock rebuilds, performance enhancements, and racing applications where minimizing ring blowby is crucial.

Each ring in this three-piece set features a 1.2mm top compression ring, a 1.5mm second ring, and a 3.0mm oil control ring, all engineered to effectively seal combustion pressure while managing crankcase vapors and oil return. NPR rings are manufactured to stringent tolerances, ensuring proper bore fit and minimizing wear-in time, which results in consistent sealing across the entire RPM range.

This piston ring set is an excellent choice for anyone involved in rebuilding or modifying small-block and big-block V8 engines, particularly in classic muscle cars, trucks, hot rods, and performance street builds. Whether restoring a Chevrolet, Ford, Mopar, or Pontiac engine, the NPR 20-GNHM3905K8 helps maintain proper compression and reduces oil consumption for optimal performance.
