Specifications

The ASF-4000644 Fifth Wheel Jaw Kit from HME is a critical replacement component for maintaining safe and reliable fifth wheel operation. Fifth wheel jaws experience constant stress and wear during coupling and uncoupling, which can compromise secure kingpin engagement over time. This jaw kit is engineered to restore proper locking performance and durability in Simplex-style fifth wheels. Manufactured to meet heavy-duty demands, it helps reduce downtime, improve safety, and extend the overall service life of the fifth wheel assembly. Available from Wofford Truck Parts.
