XA-S36
Base Slider Assembly, Inboard, Heavy-Duty, 36 in
SAF-Holland

Dedicated to delivering reliable motion control in a heavy-duty fifth-wheel system, this base slider assembly provides inboard kingpin travel of 36 inches, enabling adjustable clearance and optimized hitch geometry across varying tractor and trailer configurations. The inboard arrangement enhances protection from debris and reduces exposure of critical wear surfaces, promoting consistent wear patterns and extended service life. The VMRS designation places this component squarely within the fifth-wheel family, supporting accurate cross-referencing in maintenance databases and OEM service manuals. Its robust construction supports high-cycle cycling typical of fleet operations, contributing to smoother engagement and disengagement during coupling cycles. Compatibility with standard mounting patterns ensures straightforward replacement or retrofit with other base slider components, minimizing downtime. In practice, operators benefit from improved load transfer stability, predictable hitch position, and reduced wear on adjacent rails and kingpin surfaces. Routine lubrication and periodic inspection are recommended to preserve performance across long service intervals and diverse operating conditions, from regional hauls to heavy long-haul duties.
