Mahle 41855CP Engine Piston Ring Set

Engine Piston Ring Set Overview

Mahle 41855CP is a premium engine piston ring set built to OE-driven standards for controlled friction, reduced oil consumption, and long service life. It is a standard-size set with a 3.386-inch bore diameter and shallow-groove oil ring design.

Compatible with Chrysler 300, Sebring, Cirrus, Concorde, and Intrepid, plus Dodge Avenger, Charger, Magnum, Stratus, and Intrepid applications across the listed years. This part number, 41855CP, is specified for a range of 1998-2010 Chrysler and Dodge engines that use the matching ring dimensions and materials.

• Standard oversize specification for direct engine rebuild use
• Plasma-moly face coating for improved ring surface durability
• Top ring in carbon steel, second ring in cast iron, and oil ring assembly in stainless steel
• Shallow groove oil ring assembly for the listed application requirements
• Premium-grade construction for rebuilds that require precise ring fitment

Detailed Fitment and Function

Mahle 41855CP is engineered for engine rebuild work where ring sealing, oil control, and friction management matter. The ring pack uses a 1.50 mm top ring, 1.50 mm second ring, and 3.00 mm oil ring assembly, with a plasma-moly face coating on the ring surface and a stainless steel oil ring assembly for the specified bore size. In Chrysler 300 and Dodge Charger applications, as well as Chrysler Sebring and Dodge Stratus applications, the part is matched to the listed standard-size configuration and shallow-groove design.

This part cross-references Hastings Piston Rings 2M4946 and Sealed Power E904K for the same application.

What This Part Helps Address

• Excessive oil consumption from worn or damaged piston rings
• Loss of cylinder sealing during engine rebuilds
• Reduced compression caused by ring wear
• Friction-related wear in high-mileage engines
• Ring fitment issues when restoring standard-bore engines

Installation Notes and Quality

Verify bore diameter, ring thickness, and groove type before installation. Clean piston ring grooves thoroughly and confirm end gaps and ring orientation against the engine builder’s specifications for the exact Chrysler or Dodge application.

Mahle piston rings are developed around OE requirements and are known for advanced ring technology focused on friction control, oil management, and service life.
