XA-351-A-L-P
Top Plate
SAF-Holland

A Holland-based upper mounting surface designed for robust fifth wheel coupling systems. The VMRS code 059-001-001 categorizes it within the primary family of mounting hardware used to stabilize the interface between tractor and trailer. Cross references include JOS JSK37HSL, JOS JSK37HSLX5, and SGO JSK37HSL, signaling established compatibility with linked Holland and supplier ecosystems and providing a framework for parts substitution within approved configurations. The category context underscores its role as a standard top plate variant within the fifth wheel hardware lineup, supporting precise alignment, even load distribution, and durable performance under repeated coupling cycles. In field use, expect a reliable seating plane that maintains kingpin geometry, reduces wear on mating components, and contributes to predictable disengagement forces, all of which support fleet safety, efficiency, and uptime. The design is oriented toward compatibility with a broad range of Holland-related interfaces while remaining consistent with OEM guidelines for installation, torque, and maintenance intervals. Category context: Fifth Wheel hardware with Holland-specific compatibility and cross-reference support.
