Carrillo S12845N CPP High-Performance Piston Ring Set

The Carrillo S12845N is a CPP (CP-Carrillo Performance) piston ring set engineered to match CP-Carrillo's precision-machined forged pistons. Designed for high-performance and racing applications, these rings deliver superior sealing, reduced friction, and exceptional durability under extreme operating conditions.

Key Features:

• Application-Specific Fit: Ring sets are manufactured to fit specific bore sizes for precise end gap and optimal sealing performance
• Gas Nitrided Top Ring: Offers exceptional surface hardness and wear resistance; identifiable by its uniform light gray appearance
• Napier-Style Second Ring: Hooked face design improves oil control compared to conventional taper-faced rings, acting as an effective wiper ring
• 3-Piece Oil Control Ring: Includes expander and two rails engineered to provide correct tension when seated in the cylinder bore
• Reduced Friction Design: Thinner ring profiles minimize friction for improved power output and engine efficiency
• Racing-Grade Construction: Built to withstand forced induction, nitrous, and high-horsepower naturally aspirated applications

CP-Carrillo ring sets are designed exclusively for use with CP-Carrillo pistons. OEM rings are not interchangeable with CP-Carrillo piston grooves. Always verify ring end gap before installation and follow CP-Carrillo's recommended honing specifications for maximum ring seal and engine longevity.
