XA-07871-3
Base S/A Slide
SAF-Holland

Base S/A Slide with mounting plate length of 46.20 inches represents a primary travel and alignment track within the fifth wheel assembly. The base slide is essential for regulating the relative motion between the tractor and trailer, facilitating smooth articulation and controlled engagement during coupling. Its dimension, combined with safe load paths and precise tolerances, ensures consistent slider travel and predictable latch timing, which are critical for safe and reliable towing. The VMRS code 059-001-045 designates this item as a base slide component, and cross-reference data includes HLD XA07871 3, confirming compatibility with the associated slide family. Category_id 42763 places it in the base slide subgroup of the system, where technicians reference fitment charts and service guidance. In practical terms, fleets rely on this part to maintain proper alignment of the fifth wheel assembly, minimize side movement during operation, and extend service life by reducing wear concentrations on rails. Correct installation, lubrication of contact surfaces, and periodic inspection help sustain smooth operation through thousands of coupling cycles in demanding logistics environments.
