MAHLE 224-2770.040 Engine Piston Set

The MAHLE 224-2770.040 Engine Piston Set delivers original equipment quality and performance for engine rebuilds and replacements. MAHLE is one of the largest OE piston manufacturers in the world, and this set reflects the same engineering standards found in factory-installed components.

Key Features:

• Compensated Ring Grooves: Engineered to ensure proper ring loading and precise oil control throughout the piston's service life
• Expansion-Controlled Design: Tight fitting clearances reduce engine noise, minimize wear, lower emissions, and improve overall oil control
• Ready-to-Install Kit: Includes mounted piston rings, wrist pin, and retaining clips for a complete, convenient installation
• OE-Grade Materials: Manufactured to the same specifications and tolerances as original equipment pistons
• Oversize Bore (.040"): Designed for engines requiring a standard .040-inch overbore, ideal for engine rebuilds restoring proper cylinder-to-piston clearance

The .040 oversize designation (part of the MPN suffix) indicates this piston set is sized for cylinders bored 0.040 inches over the standard dimension — a common engine rebuilding specification. MAHLE's global OE manufacturing heritage ensures consistent quality, dimensional accuracy, and long-term reliability for professional engine builders and experienced DIY mechanics alike.
