FW35-J818XL00
Fifth Wheel Assembly, Sliding
SAF-Holland

This sliding-type unit within the FW35 family brings additional fore-aft adjustability to the same rugged coupling interface used across standard tractor-trailer pairings. A 2-inch kingpin interface, combined with a substantial maximum load capacity of up to 150,000 pounds and a maximum vertical load of 55,000 pounds, supports demanding heavy-haul and multi-drop applications. The slide mechanism enables precise kingpin-to-coupler alignment when tractor and trailer assignments change or when payload balance shifts, reducing tipping risks and wear on mating surfaces. The width and compatibility dimensions are tailored to accommodate standard trailer widths and mounting footprints in the FW35 lineup, with VMRS code 059-001-135 ensuring consistent maintenance documentation. This configuration is well-suited for high-mileage fleets performing frequent hitch re-positioning or ballast adjustments, including heavy freight, bulk, and equipment transport operations. With cross-reference support in the FW35 ecosystem and category 42518 alignment, swapping to this slider variant can be accomplished with minimal downtime and tooling, maintaining fleet productivity.
