Plates and Pocket Kit
SAF-Holland

Plates and pocket kit combines mounting plates with the pocket assembly to form a complete interface between the tractor frame and the fifth-wheel head. The package emphasizes robust load distribution, precise alignment, and secure pocket retention to maintain proper kingpin geometry under heavy-duty loads. VMRS 059-001-032 positions it within the lever and plate subgroup for latch assemblies, while category 42521 reflects its application to standard fifth-wheel plate configurations that include pocket components. The Fifth Wheel family attribution confirms compatibility with a wide range of coupling systems, enabling fleet operators to perform efficient replacements during overhaul cycles or as part of new-truck builds. In practice, this kit supports consistent hitch alignment, reduces uneven wear on plate surfaces, and improves overall coupling reliability in long-haul, regional, and vocational operations where uptime and safety are paramount.
