Product Description
The Holland 4000501 is a genuine SAF-Holland left-hand fifth wheel locking jaw replacement kit designed for compatible Simplex Lite, Simplex II, and older Simplex fifth wheel assemblies. This kit provides the replacement locking jaw, standard eccentric jaw pin, and retaining pin needed to service worn or damaged fifth wheel locking mechanisms.
The locking jaw secures the trailer kingpin during coupling, while the eccentric jaw pin allows adjustment of the jaw position to maintain proper kingpin clearance. Replacing worn locking components helps restore dependable fifth wheel operation and secure trailer connections.
Designed for heavy-duty commercial trucking equipment, the 4000501 provides a repair solution for compatible fifth wheel assemblies without requiring replacement of the complete top plate.
