SAF-Holland

Sliding upper coupler head assembly provides adjustable kingpin engagement for heavy-duty towed loads, enabling micro-adjustments during coupling across varying ride heights. Constructed with durable alloys and tight tolerances, it resists wear while maintaining robust locking across thousands of cycles. The unit aligns with SAF-Holland mounting patterns and bears VMRS 059-001-135 classification for premium slider products. Practically, operators benefit from easier height dialing and quicker connect/disconnect cycles, especially in busy operations where time matters. The motion control remains smooth under load, reducing stress on the trailer kingpin and mounting pads. The design supports standard safety accessories and lubrication practices, promoting long service life in fleet operations. Its sliding capability helps accommodate suspension movement and road irregularities, supporting reliable trailer tracking and alignment in both regional and long-haul duty cycles. Category 42518 places this component within the sliding-coupler family, emphasizing compatibility and serviceability across SAF-Holland systems.
