This high-capacity fifth-wheel interface component provides a robust, purpose-built load path for heavy-duty tractor-trailer coupling. Engineered with a substantial footprint, the footprint dimensions measure 38.50 in in length and 32.50 in in height, delivering a broad, rigid contact surface that promotes consistent alignment and solid transfer of towing loads across a wide range of suspension configurations and trailer configurations. Classified within the fifth-wheel family, its design emphasizes long-term rigidity, dimensional stability, and dependable performance in demanding roadside and highway conditions. The large, square contact area helps minimize hitch wear and reduces lateral movement during sharp maneuvers, contributing to improved ride quality and smoother coupling cycles. This unit is cross-referenced with JOS JSK37HSL, providing a practical compatibility cue for operators and service personnel seeking interchangeable literature or replacement guidance. As part of the category that covers heavy-duty fifth-wheel assemblies, it integrates into standard mounting patterns and supports common trailer kingpin interfaces. VMRS code 059-001-001 reinforces its role as a primary, base-level top-plate component in the fifth-wheel system, making it a foundational element for safe, repeatable coupling in commercial fleets.
