Fifth Wheel Lower Coupler Assembly Repair Kit
SAF-Holland

This lower coupler assembly repair kit targets fifth wheel applications requiring restoration of the seating, locking interface, and load-bearing surfaces of the lower coupler. By supplying essential components to refurbish the lower assembly, the kit helps restore precise kingpin alignment, secure locking action, and repeatable engagement in varying road conditions. Such maintenance reduces the risk of slippage, misalignment, or binding during hitching, thereby improving overall trailer handling and safety. The VMRS code 059-001-032 identifies this as a maintenance kit for rear/slide and lower coupler components within the relevant fifth wheel systems. Category 42521 context places it among rear/slide release and lower coupler repair packages. While cross references are not listed, technicians can expect compatibility with common SAF-Holland fifth wheel lower coupling assemblies used in the category, with installation guidance provided in standard service literature. The kit supports preventive maintenance programs and rapid on-site repairs to minimize downtime in fleet operations.
