MAHLE 224-3485.040 Engine Piston Set Over OE Replacement - 040

The MAHLE 224-3485.040 Engine Piston Set delivers OE-grade precision in a .040" oversize replacement piston set engineered for demanding engine rebuild applications. MAHLE is one of the world's leading OE piston manufacturers, supplying original equipment components to major automakers and producing aftermarket parts that meet or exceed original factory standards.

Each piston is precision machined to exceptionally tight tolerances and features MAHLE's proprietary GRAFAL® graphite-impregnated resin anti-friction skirt coating, which significantly reduces drag, scuffing, friction, and cylinder bore wear during both break-in and long-term operation.

Key Features:

• OE Form, Fit & Function – Engineered to match original equipment specifications for reliable, drop-in fitment
• GRAFAL® Anti-Friction Skirt Coating – Proprietary graphite-impregnated resin reduces friction, scuffing, and bore wear
• Compensated Ring Grooves – Ensures proper ring loading and precise oil control throughout the piston's service life
• Expansion-Controlled Design – Tight fitting clearances reduce engine noise, wear, and emissions while improving oil control
• Lightweight Construction – Reduced reciprocating mass lowers bearing loads, improves engine response, and supports smoother operation
• .040" Oversize – Designed for use in bores that have been machined .040" over standard diameter
• Ready-to-Install – Includes piston pin and clips for complete, convenient installation right out of the box

MAHLE's deep expertise in piston development and manufacturing—rooted in decades of international OE engineering work—makes this set an ideal choice for professional engine builders and serious DIY rebuilders seeking factory-level quality in an oversize application.
