Unirails

Unirails, found within the Body > Panels section of our catalog, are critical structural components used in the construction of passenger cars and commercial vehicles. These long, typically steel or aluminum members run along the underside of a vehicle's body, providing a robust foundation for mounting body panels, floors, and other structural elements. Unirails contribute significantly to vehicle rigidity, crash safety, and overall durability. They are often hidden from view, forming the primary load-bearing structure beneath the cabin and cargo areas. Examples in our inventory include MAN Unirails with part numbers 81416850137, 81.08201-5940, and 81.41685-0098, specifically designed for various MAN models. Correct Unirail replacement is vital after collision damage or severe corrosion to maintain structural integrity.
