Fifth Wheel - Riser Exchange, 10-Inch
SAF-Holland

The riser exchange kit for the fifth wheel is a rebuild oriented solution targeted at restoring offset characteristics on the sliding or locking interface. The 10 inch designation specifies the travel or offset dimension critical to achieving proper alignment between tractor and trailer during hitch engagement. VMRS 059-001-135 classifies this as a fifth wheel related rebuild kit, while category context places it within the fifth wheel accommodation and load transfer subsystem. In practice, technicians can refurbish or replace the riser with this kit to reestablish correct clearance, stack height, and hitch geometry, resulting in smoother uncoupling and safer, more predictable towing performance. The kit supports preventive maintenance and midcycle service, minimizing misalignment risk and extending the service life of the fifth wheel assembly in long hauls and mixed-duty fleets.
