Carrillo CPT-3209PVD PVD Turbo Piston Ring Set 81.5mm Bore

The CP-Carrillo CPT-3209PVD is a high-performance PVD Turbo Ring Set designed for an 81.5mm (3.209") bore. Engineered specifically for forced-induction applications, this three-piece ring set combines a thicker top ring with advanced PVD (Physical Vapor Deposition) coating technology to deliver superior durability, reduced friction, and exceptional longevity under boost.

Ring Set Specifications:

• Top Ring: 1.2mm steel — thicker than standard for increased durability and resistance to ring flutter under high boost conditions
• 2nd Ring: 1.2mm steel — provides secondary sealing and oil scraping support
• Oil Ring: 2.0mm lightweight flex-vent design — delivers excellent tension and positive oil control
• Bore Size: 81.5mm (3.209")
• Coating: PVD (Physical Vapor Deposition) on the top ring face

Key Features:

• PVD Coating is harder and significantly smoother than traditional gas nitride, providing increased ring endurance and reduced friction against the cylinder wall
• The compact 2.0mm oil ring is smaller than most competing designs, allowing more material to be retained on the piston ring lands for added piston strength
• Comes standard with CP-Carrillo Sport Compact HD shelf pistons and can be paired with any custom CP-Carrillo piston
• Ideal for turbocharged and supercharged motorsport, sport compact, and high-performance street engine builds
• Manufactured in the USA by CP-Carrillo to exacting tolerances

The CPT-3209PVD ring set is part of CP-Carrillo's proven Turbo Ring Series, available in bore sizes from 81mm and up. It is the preferred choice for builders seeking a ring package that can handle the extreme cylinder pressures of forced-induction applications while minimizing parasitic friction losses.
