XA-S860-35
Base Slider Assembly, Heavy Duty
SAF-Holland

Designed for rugged heavy-duty service in the tractor-trailer interface, this base slider provides a robust, controlled slider path that enables precise horizontal adjustment of the hitching interface within fifth wheel configurations. By allowing smooth fore-aft movement and consistent alignment, it supports accurate kingpin positioning and height matching across varying trailer heights and load conditions. The result is improved coupling reliability, reduced wear on mating components, and faster hitch engagement in busy yard environments. The component is engineered to withstand high cycle loads and exposure to roadway contaminants, delivering long service life in demanding applications such as regional and long-haul fleets where uptime is critical. Classified under a fifth wheel family category, it aligns with standard maintenance and inspection protocols, aiding technicians in diagnostics and part replacement planning through consistent VMRS coding (059-001-045). Compatibility with common heavy-duty tractor chassis and trailer dollies makes it a practical upgrade or replacement in fleets seeking to optimize hitch geometry, reduce misalignment during turns, and extend the life of the fifth wheel assembly. Overall, this part contributes to safer, more reliable coupling operations and lower maintenance costs in vocational and highway operation profiles.
