Carrillo CPT-3366PVD Turbo Piston Ring Set 3.366" Bore PVD Coated

The CP-Carrillo CPT-3366PVD is a high-performance turbo piston ring set designed for a 3.366-inch (85.5mm) bore. Built specifically for forced-induction applications, this ring set delivers superior sealing, reduced friction, and exceptional durability under the elevated cylinder pressures produced by turbocharged engines.

Ring Configuration:

• Top Ring: 1.2mm steel — thicker design provides extra durability and flutter resistance at high RPM
• 2nd Ring: 1.2mm steel — precise sealing for optimum combustion efficiency
• Oil Ring: 2.0mm lightweight design with excellent tension for superior oil control

PVD Coating Technology:

• Physical Vapor Deposition (PVD) coating on the ring face is harder and smoother than traditional gas nitride
• Delivers increased ring endurance and reduced friction against the cylinder wall
• Extends service life under the demanding conditions of turbocharged performance engines

Additional Features:

• Compact 2.0mm oil ring allows more material on piston ring support lands for added piston strength
• Compatible with CP-Carrillo Sport Compact HD shelf pistons and custom CP-Carrillo pistons
• Manufactured at CP-Carrillo's Irvine, California facility using precision machining and quality inspection processes

Note: This product is not CARB-approved and is not legal for use or installation in California.

CP-Carrillo's turbo ring sets are a trusted choice among performance engine builders seeking a direct upgrade over OEM rings in high-boost, high-RPM applications.
