  The Mopar Box Sill (68377178AB) is a genuine OEM structural body component designed to reinforce and support the cargo box assembly. Built to Mopar factory specifications, this box sill ensures precise fitment, structural integrity, and long-term durability.

  Engineered for use in select Mopar trucks, this box sill helps strengthen the cargo bed structure by providing support along the lower section of the box assembly. It plays a critical role in maintaining bed alignment, supporting load distribution, and enhancing overall body rigidity during hauling and everyday operation.

  Constructed from high-quality stamped steel, this component is designed to withstand heavy loads, vibration, road stress, and environmental exposure without bending, warping, or corroding. Its durable construction helps preserve the integrity and stability of the truck bed over time.

  This component is designed as a direct replacement, allowing for proper installation using factory weld points and body repair procedures.
