Fifth Wheel Top Plate
SAF-Holland

This heavy-duty plate serves as the critical interface between the tractor and trailer in a fifth-wheel setup, transmitting vertical load and dynamic steering forces across articulation cycles. Assigned to the fifth-wheel family, its VMRS code 059-001-001 identifies it squarely within the top-plate subsystem, ensuring compatibility with standard mounting patterns and engagement surfaces used in long-haul and regional operation fleets. The machined contact surface and durable mounting plane are designed to deliver consistent kingpin engagement, reduce play over time, and promote smooth articulation under load. Within category context 42763, it participates in a broad ecosystem of fittings, jaws, and locking mechanisms that rely on predictable tolerances for reliable coupling. Although cross-reference data is not specified for this variant, it remains compatible with generic fifth-wheel assemblies and sliding platforms when paired with matching bases. Operators benefit from repeatable alignment, straightforward maintenance access, and improved trailer tracking at highway speeds. The included Prop 65 warning in the details underscores the importance of handling and materials compliance in fleet maintenance programs. Overall, this component supports robust coupling performance in demanding applications, with emphasis on surface integrity, wear resistance, and consistent load distribution across service life.
