MAHLE 3020130 Precision-Ground Performance Piston Ring Set

The MAHLE 3020130 is a precision-ground performance piston ring set engineered for high-output applications where superior sealing, reduced friction, and long-term durability are critical. MAHLE is the world's largest piston ring manufacturer, with over a century of experience supplying original equipment and aftermarket ring sets to the majority of engine manufacturers in North America.

MAHLE performance piston rings are developed using advanced piston ring simulation and computer modeling tools, enabling engineers to minimize friction losses and deliver measurable power gains. The result is a ring set that performs on the dyno and holds up on the track or street.

Key Features:

• Precision-ground ring flanks maximize ring-to-piston groove sealing for reduced blow-by and improved combustion efficiency
• Tapered Hook Groove (THG) second ring design provides superior oil control, improved combustion gas management, and enhanced top ring stability
• Performance coatings — MAHLE's ring sets are available with plasma-moly inlaid or patented HV385 supersonic thermal-spray coatings for superior bonding, increased scuff resistance, and extended service life
• Positive-twist top ring geometry promotes consistent cylinder wall contact and improved sealing under high combustion pressures
• High-strength alloy construction withstands elevated operating temperatures and the demands of high-output, boosted, or racing engines
• Engineered to OE tolerances for proper fit, fast seating, and reduced oil consumption

MAHLE performance piston rings are trusted by professional engine builders and performance enthusiasts alike. The 3020130 ring set delivers the quality and consistency expected from a global OE supplier in an aftermarket performance package.
