Mahle Rings Performance 4.150in x 1.5MM .151 RW Plasma-Moly Steel Top Ring Moly Ring Set

Mahle OE offers this performance piston ring set designed for a 4.150 inch bore. The top rings are made from plasma-moly steel, known for its strength and durability, while the second rings utilize moly construction. These rings are a key component in rebuilding or refreshing an engine, ensuring a proper seal between the piston and cylinder wall for optimal compression and oil control.

This set is built for performance applications where a reliable seal is critical. The plasma-moly steel top rings handle the high temperatures and pressures found in performance engines, helping to prevent blow-by and maintain consistent power output. The moly second rings complement the top ring's performance by aiding in oil scraping and further contributing to a solid seal.
