Carrillo CPN-3553 Gas Nitrided Steel 1.0mm Top Piston Ring

The Carrillo CPN-3553 is a Gas Nitrided Steel 1.0mm top piston ring designed for high-performance and racing engine applications. Part of CP-Carrillo's CPN ring series, this ring is engineered for use with CP-Carrillo pistons in applications requiring a 3.553" bore diameter. Gas nitrided rings can be identified by their distinctive all-silver appearance across the entire ring surface.

Key Features:

• Gas Nitrided Steel construction — provides superior hardness and wear resistance for extended service life under extreme conditions
• 1.0mm top ring profile — low-tension design reduces friction and improves engine efficiency
• 3.553" bore diameter — precise sizing for accurate fitment and optimal ring seal
• Designed for use with CP-Carrillo pistons — engineered to complement CP-Carrillo's piston lineup for a matched, optimized assembly
• USA manufactured — produced at CP-Carrillo's state-of-the-art facility in Irvine, California
• Multi-step quality inspection — each component undergoes rigorous quality control to ensure dimensional accuracy and durability

CP-Carrillo specifies the use of a torque plate during boring and honing when installing CPN gas nitrided rings to ensure maximum ring seal and bore roundness. Always follow CP-Carrillo's cylinder honing recommendations for best results.
