Fifth Wheel Riser Exchange
SAF-Holland

A height-adjustment module for standard fifth-wheel hitch systems, this exchange kit enables quick and reliable changes to the vertical geometry to suit different tractor and trailer configurations. Engineered with precision-machined mounting surfaces and compatible pedestals, it ensures accurate alignment with common kingpin interfaces and maintains consistent clearance throughout operation. By providing a straightforward reconfiguration path, it reduces labor time during maintenance and minimizes the risk of improper height settings that could affect tongue weight, steering geometry, and overall vehicle handling. The VMRS code 059-001-135 situates the component within the fifth-wheel height and alignment subsystem, underscoring its importance in maintaining safe, predictable coupling across varied loads. Category context 42518 highlights its role in fifth-wheel adjustments and modular upgrades. In practice, the part is used during fleet upgrades, when integrating new tractors and trailers, or when optimal height is needed for unloaded versus loaded conditions. Cross references are not listed, indicating standalone compatibility with standard mounting footprints while encouraging verification of fastener patterns and shim requirements for repeatable performance in rugged working environments.
