MAHLE 315-0004.035 Performance Piston Ring Set +0.035" Oversize

The MAHLE 315-0004.035 Performance Piston Ring Set is a precision-engineered ring pack designed for high-performance and racing engine builds. Built to MAHLE's exacting standards, this set delivers superior combustion sealing, reduced friction, and exceptional durability in demanding applications. The .035 oversize designation makes it ideal for engines that have been bored 0.035" over standard.

Key Features:

• Plasma-moly coated ductile iron top ring — barrel-faced profile for fast break-in and long-term wear resistance
• Reverse-twist cast iron second ring — optimized for improved oil control and combustion sealing
• Low-tension oil control ring assembly — reduces parasitic drag to maximize horsepower output
• Ultra-flat ring flanks — maximize ring-to-piston groove sealing for superior compression retention
• File-fit design — allows precise end gap sizing for your specific application
• +0.035" oversize bore — engineered for engines bored 0.035" over standard dimensions

MAHLE pioneered the use of piston ring simulation and computer-aided development tools to engineer rings that deliver measurable horsepower gains by minimizing internal friction. Each ring in the set is manufactured to tight tolerances using premium materials and advanced coatings, ensuring consistent performance whether on the street or the track.
