MAHLE 224-3443WR.040 Engine Piston Set with Rings Pin Clips

The MAHLE 224-3443WR.040 is a complete engine piston set engineered to original equipment (OE) standards. MAHLE is one of the largest OE piston manufacturers in the world, supplying major automakers globally, and this piston set delivers that same factory-level quality directly to the engine builder or professional technician.

Each piston features compensated ring grooves that ensure proper ring loading and precise oil control throughout the engine's service life. The expansion-controlled piston design allows for tight fitting clearances, which directly reduces engine noise, minimizes wear, lowers emissions, and further improves oil control compared to lower-quality aftermarket alternatives.

Key Features:

• OE quality construction matching original manufacturer specifications
• Compensated ring grooves for optimal ring loading and oil control
• Expansion-controlled design for reduced fitting clearance
• Reduces engine noise, wear, and emissions
• Ready-to-install complete set — includes mounted piston rings, wrist pin, and retaining clips
• 0.040" oversize bore dimension for use in properly re-bored or honed cylinders
• Sourced from one of the world's largest OE piston manufacturers

The 224-3443WR.040 designation indicates this is a 0.040" oversize set, intended for engines where the cylinder bores have been machined to the corresponding oversize specification. Everything needed for installation is included, making this an ideal choice for professional engine builders and serious DIY rebuilders alike.
