MAHLE 224-3415.040 Engine Piston Set Over OE Replacement - 040

The MAHLE 224-3415.040 is a complete .040" oversize engine piston set engineered to OE standards for a precise, drop-in replacement during engine rebuilds. As one of the world's largest original equipment piston manufacturers, MAHLE brings factory-level quality and engineering directly to the aftermarket.

Each piston is precision-machined to exacting tolerances and features compensated ring grooves that ensure proper ring loading and consistent oil control throughout the service life of the engine. MAHLE's expansion-controlled skirt design maintains tight piston-to-wall fitting clearances, which directly reduces engine noise, minimizes wear, lowers emissions, and enhances oil control.

This set is designed for builder-ready installation — pistons arrive with mounted piston rings, wrist pins, and retaining clips included, so no additional hardware is needed to complete the assembly.

Key Features:

• .040" oversize bore diameter for use in freshly bored and honed cylinders
• OE-quality construction — same form, fit, and function as original equipment pistons
