This is a king pin kit for a heavy-duty trailer. The king pin serves as the pivot point that locks into the tractor's fifth wheel, allowing the trailer to articulate.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
The kit includes a king pin with a 3/8‑inch thick bolster plate that bolts to the trailer’s upper coupler. These components are replaced when the king pin is worn below service limits, galled, bent, or damaged, to maintain safe and secure coupling.
