Fifth Wheel, Sim, 12 in. Slider, 8.25 in., Left-Hand
SAF-Holland

This slider-enabled fifth wheel configuration emphasizes a longer 12-inch slider with an 8.25-inch mounting-to-saddle footprint and a left-hand orientation, catering to applications that require additional forward and backward hitch travel to accommodate larger trailers or variable-length kingpin centers. The arrangement promotes smoother engagement and reduced peak loads during coupling, as the sliding interface helps align the kingpin with the saddle more consistently across irregular road surfaces. As with other slider-based assemblies, the VMRS designation places this component in the primary towing and steering subsystem, underscoring its role in critical pivoting and load-transfer functions. Benefits include enhanced ride stability for both tractor and trailer, improved wear life of locking latches due to controlled engagement, and easier adjustment when pairing with compatible saddles. Proper installation demands attention to slider preload, lubrication intervals, and saddle compatibility to prevent side-load wear. While no cross references are listed, users should compare the vehicle’s saddle geometry and kingpin centerline requirements to ensure reliable coupling across standard and specialty trailers in fleet operations.
