XA-J748
Base and Bracket Assembly
SAF-Holland

A purpose-built interface for fifth-wheel couplings, this assembly focuses on a rigid, high-durability mounting solution with easy maintenance access. It is designed to work with a range of trailer configurations and tractor frames, providing consistent load transfer paths and predictable engagement characteristics. The slider-style adjustment and standard mounting interfaces support rapid trailer changes and straightforward torqueing procedures, minimizing downtime during fleet rotations. VMRS code 059-001-045 places the unit in the corresponding base/bracket assembly family, ensuring compatibility with related kits and facilitating cross-model service parts planning. In practice, operators benefit from improved alignment accuracy, reduced rework during hookups, and enhanced resistance to misalignment and pin wear under heavy towing conditions. The category context reinforces its place within a family of interchangeable mounting solutions, enabling standardized procurement across multiple vehicle models and operations.
