Base Slider Assembly for Fifth Wheel
SAF-Holland

The fifth-wheel specific variant blends a base slider with the dedicated fifth-wheel interface for straightforward retrofit or replacement in tractor-trailer configurations. It supports the essential movement range required to adjust the trailer relationship to the tractor, aiding weight distribution and hitch engagement consistency. VMRS 059-001-045 identifies it within the standard slider family, with category 42763 placing it in the core base-slider assembly lineup. This configuration is particularly advantageous for fleets prioritizing compatibility with existing fifth-wheel mounts and minimal rework during service events. In practical use, technicians benefit from a predictable travel path, reduced risk of binding, and stable positioning across mounting contexts. Regular checks should include distance and alignment verification, along with lubrication of movement surfaces to preserve performance across varying loads and road conditions.
