HLDFW35, OB ILS, 12 in, 6.81 in, 31 LK
SAF-Holland

This integrated low-weight slider represents a purpose-built solution for fleets prioritizing reduced unsprung weight without sacrificing load capacity. The component combines a 12-inch width with a 6.81-inch travel range and a 31 LK designation that reflects specific kingpin geometry and locking interface. Its inboard SDS mounting and left-hand release provide precise control over slide-in engagement, enabling quick coupling while maintaining secure retention during transit. The assembly supports heavy-duty operations with a VMRS code of 059-001-135, aligning with standard maintenance documentation for fifth-wheel components. With a stated capacity and integrated slider, it enables more agile trailer positioning on tight docks or in congested yards, improving maneuverability for long-haul and multi-stop operations. The category context highlights its role within the fifth-wheel family as a modular, performance-driven option that enhances coupling flexibility and fleet efficiency. Cross references include JOS JSK37USL and U8BG24, signaling compatibility with select slider families and facilitating informed procurement decisions. Overall, this unit delivers an optimized balance of strength, weight reduction, and precise travel, supporting safer, faster hitching cycles and reduced wear on rails and kingpins across frequent industry applications.
