Product Description

The Volvo Penta Primary Shaft 873013 is a genuine OEM driveline component designed for Volvo Penta sterndrive systems.

Precision-machined to exact OEM tolerances, this primary shaft ensures proper alignment, smooth power delivery, and long service life under high-load marine conditions. It is engineered for durability and resistance to wear, making it essential for maintaining reliable driveline performance.
