SAF-Holland

This longer, slider-enabled mounting platform extends fore-aft adjustability to accommodate a wider range of trailer configurations while maintaining a consistent footprint on the truck frame. Overall dimensions show a width of 39.50 inches, height of 2.0 inches, and length of 57.50 inches, with a 33.62-inch frame width and 36 inches of travel. The outboard mounting style continues to offer straightforward installation, clearance from cab components, and simplified maintenance access. As a member of the fifth-wheel family, it is designed to engage standard kingpin couplings with predictable load paths and repeatable engagement under heavy towing conditions. VMRS code 059-001-045 situates this item within the base/bracket assembly subgroup, ensuring compatibility with other kits in the same family and facilitating cross-model interchangeability across fleets. Practical benefits include faster trailer swaps, consistent pin alignment, reduced downtime during maintenance cycles, and improved stability when negotiating uneven surfaces or dynamic road loads. The category context confirms alignment with related mounting solutions, enabling standardized procurement and streamlined service planning across multiple truck models and trailer configurations. Strong rotational and lateral load control translates to improved ride quality and safer, more reliable couplings in demanding environments.
