XA-S836
Base S/A Slide
SAF-Holland

Base cross-member slide compatible with side-of-frame mounting for fifth-wheel systems, this base component is a critical interface for adjusting the articulation range of the trailer's universal docking platform. It carries the Fifth Wheel (S/A) pairing designation and is rated for the loads typical of high-usage linehaul operations. The safety and alignment of the slide are essential to achieve predictable kingpin engagement, minimize hitching time, and ensure safe decoupling under varying road grades and weather. The two-stage lubrication and corrosion-resistant finish support longevity in harsh environments, and the part’s VMRS 059-001-003 ties it to the standardized selector and replacement framework used by chassis and trailer systems. Category 42807 situates the part within the broader fifth-wheel slide ecosystem, which fleets rely on for compatibility with multiple kingpin configurations and compatible base plates. In practical terms, technicians will value the component’s straightforward installation, consistent travel tolerance, and reliable engagement characteristics that support efficient daily operations in cross-docking facilities and highway dispatch centers.
