XA-J912
Base and Bracket Assembly
SAF-Holland

Designed to anchor heavy-duty fifth-wheel interfaces to the tractor frame, this mounting solution provides a rigid base plate and bracket support that secure the hitch system to the chassis. The precision-machined interface ensures alignment with standard rails, promoting uniform load transfer across the mounting footprint and reducing hitch play during docking, articulation, and highway operation. By distributing vertical and lateral loads through robust welds and standardized fastener patterns, it helps extend service life of mating components while minimizing maintenance intervals. Technicians will value straightforward installation using common hardware and predictable seating tolerances, enabling quick retrofits on compatible tractors. In service, the mounting arrangement contributes to consistent hitch geometry across varied loads and road conditions, delivering smoother towing and reduced wear on the hitching surfaces and adjacent brackets. VMRS 059-001-045 places this item within the trailer-coupling subsystem, aiding maintenance planning and cross-referencing. Category context places it in the Fifth Wheel family, illustrating its role as a foundational mounting element in heavy-duty coupling systems. Safety labeling aligns with Prop 65 guidelines; handle and service instructions should be followed to minimize exposure to hazardous substances.
