XA-A936
Slide Base Assembly
SAF-Holland

The base assembly showcases a longer travel length and taller profile, reflecting its suitability for heavier duty coupling scenarios where extended stroke and engagement reach are required. Width remains aligned with standard interface footprints at 39.50 inches, while the height of 8.70 inches and a travel length of 36 inches translate into a broader envelope for kingpin engagement and alignment tolerance. The overall length of 55 inches supports stable tracking of the sliding element and improved load distribution along the base rail. VMRS code 059-001-045 places this part within the recognized channel for slide base assemblies, ensuring compatibility with existing rails, mounting patterns, and service procedures. The extended travel and length enhance compatibility with a wider range of tractor-trailer configurations, enabling operators to accommodate different kingpin positions and coupling geometries without compromising safety or performance. Category context reinforces its role as a high-capacity base assembly that underpins reliable docking cycles in demanding line-haul operations.
