The Victor (MAHLE) 42100CP Engine Piston Ring Set is a premium OE-replacement ring set engineered to restore compression, minimize oil consumption, and extend engine service life. Designed to meet or exceed original equipment specifications, this set is an ideal choice for engine rebuilds or compression restoration on compatible 4-cylinder applications.

Key Features:

• OE Form, Fit, and Function: Engineered to match original equipment specifications for a direct, reliable replacement
• SAE 9254 High Alloy Steel Top Rings: Delivers superior tensile and yield strength, extended fatigue resistance, and increased material hardness for long-lasting durability
• Napier Second Rings: Provides superior oil control, improved combustion gas management, enhanced top ring stability, and optimal sealing to minimize power loss
• CP-20 Oil Ring Assembly: Features an exclusive 20-degree ear angle for the best possible side seal in the piston oil ring groove, plus a special chemical polish on the expander for enhanced oil drain-back
• Barrel-Faced Compression Rings: CNC-controlled gap chamfer optimizes compression and reduces blow-by
• Pre-Lapped for Fast Seating: Rings are pre-lapped at the factory to seat immediately, virtually eliminating traditional break-in time
• Reduced Friction Design: Ring tension and coatings are optimized per application to minimize friction and improve efficiency
