Mahle 41497CP Engine Piston Ring Set

Engine Piston Ring Set Overview

Mahle 41497CP is a premium engine piston ring set built for 4.000-inch bore applications. It uses a plasma-moly face coating, carbon steel top and second rings, and a stainless steel oil ring assembly to support controlled oil use and reduced friction.

Compatible with a wide range of Ford, Mercury, and Lincoln V8 applications, including Ford F-150, Mustang, and Explorer fitments. The 41497CP is a standard oversize piston ring set with a shallow-groove oil ring design for engines that require this specific ring package.

• 4.000-inch bore diameter for matched engine rebuild applications
• Plasma-moly ring face coating for wear-resistant contact surfaces
• Carbon steel top and second rings for consistent sealing performance
• Stainless steel oil ring assembly with shallow groove design
• Premium-grade construction for rebuild work that follows OE-style requirements

Detailed Application Notes

Mahle piston rings are engineered around OE requirements, with a focus on lowering friction, reducing ring mass, and helping control engine oil consumption while supporting longer service life. This 41497CP piston ring set is used in rebuilds where standard bore sizing and the listed ring dimensions must match the engine specification. It is a direct-fit choice for many classic Ford, Mercury, and Lincoln platforms, including Ford Mustang, Ford Bronco, and Lincoln Town Car applications.

This part cross-references Hastings Piston Rings 2M4346 and Sealed Power 10444KX for the same application.

Common Rebuild Issues It Can Address

• Excessive oil consumption from worn or tired ring packs
• Loss of cylinder sealing during engine overhaul
• Increased blow-by caused by ring wear
• Reduced compression from damaged or fatigued piston rings
• Friction-related wear in high-mileage rebuilds

Installation Notes and Tips

Verify bore diameter, ring thickness, and groove style before installation. This set is intended for engines that call for a 4.000-inch standard bore and the listed ring dimensions. Clean piston ring grooves thoroughly and confirm end gaps during assembly to match the engine builder’s specifications.

Quality Assurance

Mahle develops piston rings to OE-level technical requirements and emphasizes friction control, oil management, and service life in its ring designs. Part number 41497CP reflects that engineering focus for rebuild applications that demand precise ring fitment and stable sealing performance.
