Mahle 51496CP Engine Piston Ring Set

Mahle 51496CP Piston Ring Set

Mahle 51496CP is a standard engine piston ring set built for OE-style service in select Ford, Mercury, and Mazda applications. It uses a 3.504 in bore diameter and ring materials chosen for sealing performance, oil control, and long service life.

Key Features

• Standard bore diameter: 3.504 in
• Standard oversize and standard item grade
• Top ring material: cast iron, 1.50 mm thickness
• Second ring material: carbon steel, 1.50 mm thickness
• Oil ring assembly: stainless steel, 4.00 mm axial height
• Shallow groove oil ring assembly design
• Non-coated piston ring face

Detailed Description

Mahle 51496CP piston rings are engineered around OE requirements, with a focus on reducing friction, controlling oil consumption, and supporting extended engine service life. The ring package combines a cast iron top ring, carbon steel second ring, and stainless steel oil ring assembly to deliver the sealing and oil-management characteristics expected in everyday rebuild work. This part number is used in applications such as Ford Taurus, Ford Windstar, Mercury Sable, Ford Ranger, Mazda B3000, Ford Aerostar, Ford Tempo, Mercury Topaz, and Ford Probe.

This part cross-references Hastings Piston Rings 5762 and Sealed Power E446X for the same application. Mahle 51496CP is a direct-fit choice for standard-bore rebuilds where correct ring thickness, groove style, and material selection matter.

What It Helps Address

• Excessive oil consumption from worn or mismatched rings
• Low compression caused by ring wear or poor sealing
• Blow-by and crankcase pressure buildup
• Reduced cylinder sealing during engine rebuilds
• Ring fitment issues in standard-bore applications

Installation Notes and Tips

Verify bore diameter, ring thickness, and groove style before installation. Mahle 51496CP is specified for a 3.504 in standard bore with 1.50 mm top and second rings and a 4.00 mm oil ring assembly. Clean the cylinder walls thoroughly, inspect ring end gaps, and confirm piston groove condition during assembly. For fitment reference, this set fits 1986-2000 Ford Taurus, 1995-2000 Ford Windstar, 1986-2000 Mercury Sable, 1991-1998 Ford Ranger, 1994-1998 Mazda B3000, 1986-1997 Ford Aerostar, 1992-1994 Ford Tempo, 1992-1994 Mercury Topaz, and 1990-1992 Ford Probe.

Quality Assurance

Mahle manufactures piston rings to meet OE-driven performance targets, with attention to friction reduction, oil control, and service life. The 51496CP part number reflects a standard replacement specification for rebuilds that require consistent ring geometry and material selection.
