Piston Ring Set – The Ultimate Performance Choice for High-Performance Engines

The CP Pistons CPN-3248 Piston Ring Set, the undisputed leader in sealing power, durability, and efficiency. Engineered for enthusiasts and professionals who demand the best, this ring set is meticulously crafted to outperform all competitors, delivering unmatched reliability and performance in high-pressure environments. Whether you’re rebuilding a race-ready block or upgrading your street machine, the CPN-3248 is the top choice for maximizing power, minimizing drag, and ensuring long-lasting engine performance.

Why CP Pistons Piston Ring Set?

Sealing Performance:

Designed to seal the combustion chamber with precision, preventing gas leakage into the crankcase and oil contamination in the chamber. This ensures optimal compression and power output, making it the go-to choice for high-performance applications.

Durability:

Built with cutting-edge materials and advanced manufacturing, the CPN-3248 withstands extreme conditions, offering extended life even in the most demanding racing environments.

Low-Tension, High-Efficiency Design:

The innovative flex-vent oil ring reduces friction on the cylinder wall, boosting engine efficiency and performance while maintaining exceptional oil control.

Compatibility with Modern Cylinder Materials:

Gas-nitrided steel top ring ensures compatibility with Nikasil and cast iron bores, providing scuff resistance and maximum bore protection.

Trusted by Champions:

CP Pistons, a division of CP-Carrillo, is renowned for its commitment to excellence, with a legacy of powering winning engines in motorsports worldwide.

No other piston ring set matches the CPN-3248’s blend of precision engineering, performance optimization, and reliability. It’s the definitive choice for customers who refuse to compromise on quality.

Included:

The CP Pistons CPN-3248 Piston Ring Set is sold per cylinder (one set services one piston). For multi-cylinder engines, please order the appropriate quantity (e.g., 4 sets for a 4-cylinder engine, 6 for a V6, etc.). Each set includes:

  • 1.0mm Top Ring: Gas-nitrided steel compression ring, scuff-resistant and compatible with Nikasil and cast iron bores. Provides superior sealing and extended life under extreme conditions.
  • 1.2mm Second Ring: Cast iron with a Taper Hook Groove (THG) Napier design, acting as an oil wiper to push oil away from the combustion chamber, enabling a lower-tension oil ring for reduced drag.
  • 2.8mm Flex Vent Oil Ring: Comprises two soft nitride rails with a low-tension expander. The mini-flex vent design minimizes friction, enhancing engine performance and efficiency.
  • Bore Size: 3.248 inches (82.5mm), precision-engineered for a perfect fit.
  • Part Number: CPN-3248

Note: Rings are non-returnable due to their precision nature. Please verify compatibility with your piston and engine specifications before ordering.
