FW7040-7779XL
Fifth Wheel Assembly
SAF-Holland

This fifth wheel assembly adopts a kompensator plate mount OB configuration with a 40 inch width and a 36 inch length, paired with an 11.42 inch mounting height and a 2 inch king pin diameter. The left-hand release and kompensator mounting arrangement emphasize adaptability to severe-duty conditions where trailer pitch and plate dynamics can affect alignment. The assembly facilitates stable articulation during continuous loading cycles and supports long-haul tasks that demand repeatable coupling reliability. Its design prioritizes load distribution and longevity of the locking mechanism, helping to reduce maintenance intervals in high-mileage fleets. VMRS 059-001-135 assists with fleet maintenance planning and troubleshooting, and the 42518 category label situates this component squarely within the SAF-Holland fifth wheel range built for heavy-use operations. Cross references, where provided, can aid in identifying compatible retrofit options for existing fleet configurations.
