Detailed Description

MAHLE 41699.030 is built around OE-driven ring technology and is engineered to reduce friction, lower ring mass, and help minimize engine oil consumption while supporting longer service life. The ring package combines a 1.50 mm top ring, 1.50 mm second ring, and 3.00 mm oil ring assembly for rebuilds that require the listed oversize specification. This part cross-references Hastings Piston Rings (e.g., 2M4790.030) for the same application. It is a direct fit for a wide range of Dodge, Jeep, Chrysler, Mitsubishi, and Cadillac engine applications, including Dodge Dakota, Dodge Ram 1500, and Jeep Grand Cherokee rebuilds that call for this size.

What It Is Used For

• Restoring cylinder sealing after engine wear
• Reducing oil consumption caused by worn rings
• Improving compression retention during rebuild work
• Replacing rings that no longer maintain proper wall contact
• Supporting rebuilds that require a 0.030 in oversize ring set

Installation Notes and Tips

Verify bore size before installation and confirm the engine requires a 0.030 in oversize set. Match the ring package to the cylinder finish, ring groove dimensions, and rebuild specifications listed for the application. Clean ring grooves thoroughly and check end gaps during assembly. Compatible with listed Dodge Dakota, Dodge Ram 1500, and Jeep Grand Cherokee applications, along with the other vehicles shown in the fitment data.
