Fifth Wheel Top Plate
SAF-Holland

This fifth-wheel top plate component serves as the primary interface between tractor and trailer, transmitting vertical and horizontal forces through the coupling while allowing precise articulation of the articulated joint. By providing a stable, flat surface for kingpin engagement, it helps ensure even load transfer, reduces wear on the kingpin and saddle, and contributes to smoother towing dynamics during cornering, braking, and highway movements. The assembly is compatible with Holland fifth-wheel systems and is engineered to withstand the rigors of high-mileage operations, including heavy payloads and frequent engage/disengage cycles. VMRS categorization 059-001-001 supports standardized maintenance planning, part identification, and replacement workflows, while cross-references to JOS JSK37HSL expand procurement options for multi-brand fleets. Within the Fifth Wheel hardware category (42763), this component underpins reliable hitch performance, aiding in quick coupling, minimized downtime, and consistent alignment across a broad spectrum of trailer configurations. The item supports routine inspection regimes and straightforward service life extension in sustained linehaul and regional service programs.
