XA-J12
Base
SAF-Holland

The base component forms the fundamental foundation of the fifth-wheel mounting system. It provides a solid, stationary platform for the kingpin interface, ensuring reliable alignment and load transfer under dynamic towing conditions. A robust base contributes to consistent hitch geometry, reduces wear on mating rails, and simplifies routine inspections when performing downtime maintenance. Compatibility with SAF-Holland’s fifth-wheel ecosystem is supported by standardized mounting patterns, enabling straightforward replacement in fleets that rely on modular base components. VMRS coding places it squarely within the fifth-wheel base category, supporting maintenance planning, stocking, and diagnostics. Category context identifies this part as a core mounting hardware element required for safe, stable trailer connections across a broad range of heavy-duty applications. Safety guidelines, including Prop 65 notices, should be followed during installation and handling.
