MAHLE 41555CP Premium Plasma-Moly Engine Piston Ring Set

The MAHLE 41555CP is a premium engine piston ring set engineered to meet or exceed OEM performance standards. MAHLE is the world's largest piston ring manufacturer, and this set reflects their commitment to technically advanced, extensively tested ring technology built to handle the demands of modern performance and replacement applications.

These rings are designed to be installer-friendly, arriving pre-lapped to seat immediately and virtually eliminate break-in time. Ring materials, coatings, and tension are all optimized for reduced friction, minimized oil consumption, and extended service life.

Key Features:

• Plasma-Moly Face Coating — Provides superior wear resistance and faster ring seating compared to standard cast iron rings
• Barrel-Faced Compression Rings — Delivers more efficient compression and reduced blow-by for improved engine performance
• CNC-Controlled Gap Chamfer — Precisely optimizes compression and minimizes combustion gas leakage
• Reverse Twist Intermediate Rings — Enhances groove side sealing and taper race machining improves cylinder wall contact
• CP-20 Oil Ring Assemblies — Exclusive 20-degree ear angle provides optimal side sealing against the cylinder wall; chemically polished expander promotes enhanced oil drain-back
• Pre-Lapped for Immediate Seating — Reduces break-in time and gets your engine running at full efficiency faster
• Optimized Ring Tension — Engineered to minimize friction while maximizing compression and oil control

MAHLE piston rings are driven by OEM requirements and lead the industry in reducing ring mass and friction while delivering longer service life. The 41555CP piston ring set is the trusted choice for professional engine builders and serious DIY rebuilders seeking OE-quality results.
