XA351A134LP
Fifth Wheel Top Plate
SAF-Holland

The top plate assembly acts as the pivotal interface between tractor and trailer, delivering a robust, flat mating surface that supports secure kingpin engagement and controlled articulation. By evenly distributing loads and minimizing edge wear, it helps extend the service life of the saddle and kingpin while preserving hitch geometry under dynamic driving conditions. The design emphasizes durability and repeatable performance in demanding highway environments, with compatibility across Holland fifth-wheel configurations to support a broad spectrum of fleet needs. VMRS 059-001-001 categorizes this component for efficient maintenance planning and ordering, while cross references to JOS JSK37HSL enable optional substitutions in mixed-brand environments. Within the 42763 category, this part is essential for consistent hitch response, predictable coupling behavior, and reduced downtime during trips that involve frequent coupling and uncoupling. It is suitable for use in standard long-haul fleets, vocational applications, and multi-tractor operations demanding reliable fifth-wheel interfaces.
