Fifth Wheel Pocket Insert
SAF-Holland

Fifth wheel pocket inserts are inserted into the kingpin pocket to optimize engagement geometry and pocket clearance for standard fifth wheel couplings. This insert provides a controlled interface that aids precise alignment between the kingpin and saddle, reducing binding and wear during coupling and uncoupling cycles. Its VMRS code 059-001-134 places it within the fifth wheel/pocket subsystem, aligning it with other pocket-related components designed to maintain pocket geometry and engagement fidelity. Category context (42778) identifies this item as a pocket insert used in the fifth wheel pocket, a critical accessory for achieving smooth operation, consistent lock engagement, and reduced maintenance intervals on heavy-duty tractors and trailers. In practice, operators benefit from improved coupling reliability, consistent kingpin centering, and diminished wear on pocket edges and locking surfaces, contributing to safer, more efficient fleet operations in demanding hauling applications.
