Slide Base and Bracket
SAF-Holland

This slide base and bracket set, listed with a fifth wheel family attribute, emphasizes a performance-focused approach to hitch system integrity. The integration of base and bracket delivers enhanced stability for the sliding track, reducing deflection under heavy load and minimizing play that could compromise coupling precision. VMRS code 059-001-045 confirms alignment with standard maintenance practices and interchangeability with other slide base assemblies in the same category. The design supports consistent engagement geometry, promotes smoother extension and retraction cycles, and protects critical interfaces from improper clearance during dynamic vehicle operation. In practical terms, the combined assembly helps fleets maintain predictable kingpin alignment across a range of operating conditions, from heavy acceleration to steep deceleration events. Its compatibility with common mounting patterns and rails makes serviceability straightforward in the field, enabling rapid replacement and reduced downtime. Category context underscores its role as a core component of the hitching subsystem for heavy-duty configurations, ensuring reliable retrofits and upgrades within existing fleets.
