MAHLE 41608 Perfect Circle Premium Engine Piston Ring Set

The MAHLE 41608 Perfect Circle Premium Piston Ring Set delivers original equipment quality and performance for precision engine rebuilds. As one of the world's largest OE piston ring manufacturers, MAHLE brings decades of engineering expertise to the aftermarket with ring sets designed for optimal compression sealing, superior oil control, and extended service life.

Advanced Ring Technology:

• SAE 9254 high alloy steel construction provides exceptional tensile and yield strength, superior fatigue resistance, and increased material hardness
• Compression rings feature barrel-faced contact area for efficient compression and CNC-controlled gap chamfer to optimize sealing and reduce blowby
• Napier-style second rings deliver superior oil control, improved combustion gas management, and enhanced top ring stability
• CP-20 three-piece oil ring assembly with exclusive 20-degree ear angle provides optimal side seal in the piston groove and simplified installation
• Chrome-faced steel rails with stainless steel expander offer superior conformability within the cylinder bore

Performance Benefits:

• Pre-lapped design seats immediately, virtually eliminating break-in time
• Ultra-flat ring flanks maximize ring-to-piston sealing for reduced friction and power loss
• Optimized ring tension minimizes engine oil consumption while extending service life
• Precision-ground with OE form, fit, and function for trouble-free installation
• Designed to prevent incorrect installation, saving time during assembly

MAHLE Perfect Circle piston rings are engineered to meet the demanding requirements of modern engines, incorporating computer-aided design and simulation technology to reduce friction while maximizing sealing performance. Each ring set is manufactured under strict quality controls to ensure consistent reliability and long-lasting performance.
