Two-Part Up-Shock Cushions Kit (FW17)
SAF-Holland

For FW17 installations, this two-part cushion kit delivers energy-absorbing inserts that damp shock and misalignment between the kingpin and the trailer during articulation. The VMRS code 059-001-004 places the parts in the Up-Fifth Wheel subsystem, with category 42801 indicating a specialized damping component for the hitch. The two-part design allows the cushions to be installed in multiple locations or orientations, delivering tailored performance for varying load conditions and road surfaces. Benefits include smoother coupling and uncoupling cycles, reduced fretting on mounting hardware, and longer service life for the locking mechanism by absorbing peak forces during dynamic movement. In operation, the cushions help manage lateral and vertical movement that can contribute to wear or misalignment, especially on rough highways or construction routes. This kit supports routine maintenance programs and helps fleets avoid unexpected lock degradation that can jeopardize safety during lane changes or docking. There are no cross references published for this item, simplifying sourcing through standard SAF-Holland channels. The inclusion of safety labeling in the packaging complies with regulatory requirements. The category placement reflects its role as part of the hitch assembly subsystem and its importance to reliable coupling.
