Product Description
The Holland RK-4109939 is a genuine SAF-Holland fifth wheel locking jaw replacement kit designed for compatible FWS1 and FWS2 fifth wheel assemblies. This kit includes the replacement locking jaw, eccentric jaw pin, return spring, and retaining pin needed to service a worn or damaged fifth wheel jaw mechanism.
The locking jaw secures the trailer kingpin during coupling, while the eccentric jaw pin supports proper jaw positioning and movement within the fifth wheel locking mechanism. Replacing worn components helps restore dependable locking operation and proper kingpin engagement.
Designed for heavy-duty commercial trucking equipment, the RK-4109939 provides a convenient repair solution without requiring replacement of the complete fifth wheel top plate.
