MAHLE S40649 Engine Piston Pin Wrist Pin

The MAHLE S40649 is a precision-engineered engine piston pin, also commonly referred to as a wrist pin or gudgeon pin. MAHLE manufactures this component to OEM-level tolerances, ensuring a reliable fit between the piston and connecting rod within the engine assembly.

Piston pins are a critical reciprocating engine component, transmitting the force of combustion from the piston to the connecting rod. MAHLE's piston pins are manufactured from high-strength alloy steel and subjected to rigorous heat treatment and surface finishing processes to deliver exceptional wear resistance and fatigue strength under high-cycle operating conditions.

Key Features:

• OEM-quality construction engineered to MAHLE's exacting tolerances
• High-strength alloy steel construction for superior durability
• Precision ground surface finish for optimal fit and reduced friction
• Heat-treated for enhanced wear resistance and fatigue life
• Direct OEM replacement for reliable, long-lasting engine performance

The MAHLE S40649 piston pin is designed as a direct replacement part, restoring proper piston-to-rod articulation and maintaining correct piston assembly geometry for dependable engine operation.
