XA-H848
Slide Base and Bracket
SAF-Holland

Engineered as the core interface between tractor frame rails and the kingpin assembly, this sliding base and bracket assembly provides a robust, wear-resistant platform for fifth-wheel mating. The sliding base enables controlled longitudinal adjustment, allowing fleets to optimize trailer alignment for different loads and trailers without reworking chassis geometry. A reinforced bracket anchors the rails and distributes loads from dynamic cornering and braking across a wide contact surface, reducing localized stress and extending rail life. With precision machining and standardized mounting holes, installation is straightforward on compatible SAF-Holland fifth-wheel systems and aligns with common rail patterns used across popular fleets. The VMRS classification confirms its role in the fifth-wheel base family, supporting maintenance planning and parts stocking. Category context places it within the core fifth-wheel mounting hardware group, essential for correct hitch alignment, safe pin engagement, and predictable articulation. Operators gain improved hitching confidence, quicker trailer changes, and more consistent coupling geometry under varying road conditions. Proper handling and installation should follow all safety guidelines, including Prop 65 considerations highlighted in the product literature.
