Construction & Design:

Mahle OE piston rings are crafted from premium-grade steel alloys and feature a molybdenum (moly) coating on the ring face. This coating reduces friction between the piston ring and cylinder wall, enhancing wear resistance and sealing efficiency. The rings are engineered to maintain optimal tension and conform to the cylinder bore, ensuring consistent compression and reduced blow-by gases.

Each ring is precision ground and finished to tight tolerances, guaranteeing reliable performance and compatibility with the high-output SRT8 engines. The advanced design balances durability with reduced mass, contributing to smoother engine operation and improved fuel efficiency.

Installation & Fitment:

This piston ring set is designed for direct replacement on the following vehicles equipped with SRT8 engines: Chrysler 300 C (2005–2010), Dodge Charger (2006–2010), Dodge Magnum (2006–2008), Dodge Challenger (2008–2010), and Jeep Grand Cherokee (2006–2010). Installation requires standard engine rebuild procedures and should be performed by a qualified technician to ensure proper ring gap setting and piston ring orientation.

No modifications are necessary as the rings meet exact OE specifications, providing a seamless fit and reliable sealing performance.
