Trailer King Pin 2 Cruciform
SAF-Holland

This trailer king pin uses a cruciform design to deliver robust articulation between trailer and tractor, enabling smooth pivots while maintaining precise alignment under load. The cruciform geometry distributes stresses more evenly across the pin and surrounding bushings, reducing wear and improving overall coupling longevity. The king pin is manufactured to tight tolerances to ensure a secure, repeatable hitch connection and consistent coupling height, which simplifies trailer alignment during hookup and reduces the chance of uncoupling mishaps. Lubrication interfaces are designed to support long service intervals and reliable movement, even in challenging environments. Replacement is straightforward, with compatible hardware and mounting patterns designed to minimize downtime during routine maintenance. This component is essential for maintaining stable coupling dynamics, maximizing drive stability, and protecting other critical front-end elements.
