Slide Base Assembly
SAF-Holland

In a sliding fifth wheel system, this base component provides the essential support for the movable carriage that delivers fore and aft adjustment. It distributes loads from the kingpin through the slider mechanism, maintaining alignment and stability when the slider is engaged, retracted, or repositioned. By offering a solid, wear-resistant foundation, the base minimizes play and enhances the precision of the sliding action, which translates directly into smoother hooking, reduced chafing, and longer service life for all compatible subassemblies. The VMRS code places it in the slide base family, and the category association confirms its role within base and slider configurations used in many heavy-duty applications. Practical benefits include easier maintenance access, predictable engagement during dynamic towing, and compatibility with a range of sliding hardware found across OEM ecosystems. Proper installation adherence to torque and fastener specifications is recommended, and standard safety guidelines should be observed when handling and assembling components in a live truck environment.
