Carrillo CPN-3465 88mm Piston Ring Set for Sport Compact Engines

The Carrillo CPN-3465 is a high-performance piston ring set designed for 88mm (3.465") bore pistons in sport compact and small-bore engines. This single-piston ring set features CP-Carrillo's advanced CPN series design, engineered to deliver optimal sealing power with minimal friction for high-revving, high-cylinder-pressure applications.

Ring Specifications:

• Top Ring: 1.0mm gas nitrided steel compression ring
• Second Ring: 1.2mm taper hook groove (THG) Napier style cast iron ring
• Oil Ring: 2.8mm low-tension flex vent design with gas nitrided rails
• Bore Size: 88mm (3.465")

Key Features:

• Gas nitrided steel top ring provides superior compatibility with Nikasil and cast iron cylinder bores
• Scuff-resistant coating allows maximum efficiency without damaging the cylinder wall
• Taper underhook groove face on second ring enables lower tension oil ring operation
• High-strength, low-tension design reduces parasitic drag while maintaining optimal seal
• Mini-flex vent expander design in oil ring maximizes oil control with reduced friction
• Extended life and protection under extreme high-performance conditions

Compatible Applications:

This ring set fits numerous CP-Carrillo 88mm piston models and is commonly used in Nissan RB26, RB25, and SR20 performance builds, as well as other sport compact applications requiring 88mm pistons.
