MAHLE 224-3439.030 Engine Piston Set .030 Over OE Replacement

The MAHLE 224-3439.030 is an OE-quality engine piston set machined to factory specifications and offered in a .030" oversize bore for engines requiring cylinder bore restoration. As one of the world's largest original equipment piston manufacturers, MAHLE brings the same engineering standards found in factory production lines directly to the aftermarket replacement market.

Key Features:

• Compensated ring grooves ensure proper ring loading and consistent oil control throughout the piston's service life
• Expansion-controlled design allows for tight fitting clearances, reducing engine noise, wear, and emissions while improving oil management
• MAHLE GRAFAL® anti-friction skirt coating — graphite-impregnated resin reduces drag, scuffing, friction, and cylinder bore wear
• Precision-machined to tight tolerances for OE form, fit, and function in engine rebuilding applications
• Lightweight construction reduces reciprocating mass without compromising durability, resulting in smoother engine operation and improved throttle response
• .030" oversize designation accommodates standard overbore cylinder machining during engine rebuilds

What's Included:

• Complete piston set (quantity matches engine cylinder count for the application)
• Mounted piston rings pre-installed on pistons
• Wrist pins and retaining clips included — ready for installation

MAHLE Original replacement pistons are engineered for engine builders who demand factory-level quality in a rebuild. The complete, ready-to-install assembly eliminates the need to source rings, pins, and clips separately, saving time and ensuring component compatibility.
