XA331NTST
Fifth Wheel Plate
SAF-Holland

This plate is part of the core fifth-wheel platform family and emphasizes dependable load transfer and robust engagement between tractor and trailer. The surface geometry supports secure kingpin seating and consistent locking action, even under high-coupling cycles and rapid direction changes. Uniform load distribution across the mounting interface reduces localized wear and enhances structural longevity for the top-plate assembly and nearby components. The no-lube design continues to simplify maintenance while delivering predictable friction performance in diverse conditions, from freezing temperatures to hot pavement. Compatibility extends across standard chassis and trailer configurations that utilize the same mounting pattern, ensuring broad applicability in mixed-fleet environments. VMRS 059-001-001 anchors the specification within the recognized top-plate family, while Category context highlights its essential function in safe, repeatable coupling. Fleet operators benefit from reduced downtime, easier inspection routines, and consistent performance across daily operational cycles.
