Fifth Wheel, 48 in., 8 in., Left Hand
SAF-Holland

This rugged vehicle-to-trailer coupling component is engineered for demanding heavy-haul applications, delivering a reliable interface between the tractor and semi-trailer with precise adjustability. The footprint, measured at 39.50 inches in width and 87 inches in length, along with a travel range of 48 inches and a mounting height of 8 inches, establishes a versatile fitment envelope suitable for standard mounting rails and rail adapters. The slide-mount construction enables fore-aft positioning to optimize kingpin alignment with the trailer saddle, improving latch engagement and reducing transient stresses during acceleration, braking, and cornering. With a maximum load capacity in the vicinity of 79,366 pounds, this unit balances high strength with predictable behavior in extreme duty cycles, such as heavy regional haul and construction support operations. The included specifications align with common OEM and aftermarket rails, allowing straightforward retrofits and serviceability in the field. VMRS code 059-001-135 anchors the part within the universal classification for coupling assemblies, while cross-reference FON SLH7AWB775048 provides an alternate designation for interoperability across SAF-Holland product lines. Category context (42518) places this component among other high-capacity towing interfaces designed for robust fleets. In practice, fleets benefit from adjustable travel length, solid mounting, and consistent engagement, which translate into safer handling, reduced downtime, and extended service life under heavy loads and varying terrain.
