Mahle 51716 Engine Piston Ring Set

Engine Piston Ring Set Overview

Mahle 51716 is a standard piston ring set for 4.000-inch bore applications. It is built around cast iron top and second rings with a stainless steel oil ring assembly to support controlled oil use and consistent sealing in the cylinder block.

Compatible with a wide range of Dodge truck, van, and SUV applications, including Dodge Dakota, Dodge Durango, and Dodge Ram 1500 fitments. The 51716 ring set is also listed for several Ram 2500, Ram 3500, and B-series applications.

Key Features

• 4.000-inch bore diameter for standard-size engine rebuilds
• Cast iron top ring and second ring for proven ring pack construction
• Stainless steel oil ring assembly for corrosion resistance and oil control
• Shallow groove design for listed OE-style applications
• Standard grade and standard oversize configuration

Detailed Application Notes

Mahle 51716 is engineered for engines that require a standard piston ring set with shallow groove dimensions. The ring pack uses cast iron for the top and second rings, while the oil ring assembly uses stainless steel to help maintain stable oil control and reduce friction in service. This part cross-references Hastings Piston Rings (e.g., 4726) for the same application.

Fitment includes 1993-2003 Dodge Dakota, 1998-2003 Dodge Durango, 1994-2003 Dodge Ram 1500 and Ram 1500 Van, 1994-2002 Dodge Ram 2500 and Ram 3500, 1995-2003 Dodge Ram 2500 Van and Ram 3500 Van, 1995-1996 Dodge Ram 4000, 1993 Dodge D150/D250/D350, W150/W250/W350, and Ramcharger, plus 1998 Jeep Grand Cherokee. The 51716 part number is used across these standard-bore applications.

Common Repair Uses

• Restoring cylinder sealing after ring wear
• Reducing oil consumption caused by worn rings
• Correcting low compression from ring fatigue or glazing
• Replacing damaged rings during engine overhaul
• Supporting proper oil control in standard-bore rebuilds

Installation Notes

Verify bore diameter, groove style, and ring thickness before assembly. Clean the piston ring grooves thoroughly and confirm end gap, side clearance, and ring orientation during installation. Match the ring set to the engine specification and the listed fitment before final assembly.

Quality Assurance

Mahle designs piston rings to OE requirements, with an emphasis on reduced friction, lower ring mass, controlled oil consumption, and long service life. The 51716 part number reflects that OE-focused engineering approach.
