Carrillo CPT-3504PVD Turbo Piston Ring Set 3.504 Bore PVD Coated

The Carrillo CPT-3504PVD is a high-performance turbo piston ring set engineered for forced-induction applications requiring maximum durability and reduced friction. Designed for a 3.504-inch (89.0mm) bore, this three-piece ring set delivers the precision and reliability demanded by serious performance builders and racers.

Ring Set Configuration:

• 1.2mm Top Ring — Thicker steel construction for enhanced durability and improved flutter resistance at high RPM and boost levels
• 1.2mm Second Ring — Matched steel second ring for optimal sealing performance under boost
• 2.0mm Oil Ring — Lightweight design that delivers excellent tension for superior oil control while allowing more piston ring land material for added piston strength

PVD (Physical Vapor Deposition) Coating:

• Applied to the face of the top ring for a surface harder and smoother than traditional gas nitride coatings
• Significantly reduces friction against the cylinder wall
• Provides increased ring endurance and extended service life under high-boost, high-temperature conditions

The CPT-3504PVD ring set is compatible with CP-Carrillo Sport Compact HD shelf pistons and can also be specified with any custom CP-Carrillo piston build. It is an ideal choice for turbocharged sport compact and performance engine builds requiring a proven, race-tested ring package.
