MAHLE 41593 Perfect Circle Original Piston Ring Set Component

The MAHLE 41593 is a Perfect Circle Original piston ring part/component from MAHLE, the world's largest manufacturer of piston rings. Engineered for reliable engine rebuilds and re-ring applications, this component is part of MAHLE's trusted Original line — formerly Perfect Circle, trusted by professional automotive technicians for over 100 years.

Key Features:

• Steel piston rings offer higher tensile strength, higher yield strength, greater fatigue life, and greater hardness while still offering a lower ring mass — leading to better stress resistance, reduced groove pound-out, longer service life, better conformability, superior oil economy, and improved blow-by control while lowering friction.
• Pre-lapped to seat immediately, virtually eliminating break-in time, with ring materials and coatings as well as ring tension all optimized for reduced friction and extended life.
• Compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by.
• Intermediate rings incorporate a reverse twist design for better groove side sealing, and taper race machining to enhance contact.
• Extensive OE connections give MAHLE piston rings a technological edge, including the CP-20™ oil ring, narrow compression rings, steel compression rings for gasoline engines, low-tension oil rings, and coated compression rings for diesels.
• Rings are built so they cannot be installed incorrectly — an important feature that saves time and reduces the risk of installation errors.

MAHLE Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders. Whether performing a full overhaul or a simple re-ring, the MAHLE 41593 delivers the precision and durability demanded by professional technicians and serious DIYers alike.
