Construction & Design:

Mahle OE piston rings are crafted from high-grade steel alloys and feature a molybdenum (moly) coating on the ring face. This coating significantly reduces wear by providing a hard, low-friction surface that withstands the harsh conditions inside the combustion chamber. The rings are precision-machined to exact tolerances, ensuring a perfect fit within the piston grooves and cylinder walls. This meticulous engineering helps maintain a tight seal, which is critical for efficient combustion and engine performance.

The ring set includes compression rings and oil control rings designed to work in harmony, balancing sealing capability with oil regulation to protect engine components and optimize fuel economy.

The Mahle OE Moly Ring Set is designed for direct fitment on numerous Chrysler, Dodge, Jeep, and Ram models produced between 2011 and 2017. Installation requires standard engine rebuild procedures, including proper piston ring gap measurement and careful ring orientation. No modifications are necessary when replacing worn or damaged rings with this set, making it a straightforward upgrade for engine rebuilds or repairs.

Ensure that cylinder walls are properly honed and cleaned before installation to maximize ring seating and sealing effectiveness.
