SAF-Holland has a removable and replaceable 2-inch AAR kingpin system for hot-dip galvanized upper couplers. The patented system meets Association of American Railroads specifications, and features a machined kingpin and housing.

The kingpin housing is welded into the trailer’s upper coupler prior to the hot-dip galvanization process, completely protecting the upper coupler against corrosion. After galvanizing, the kingpin is secured in the housing with a special nut and coller fastener, allowing the kingpin to remain removable and replaceable over the life of the trailer.

“This new AAR Kingpin System answers the OEM’s challenges of hot dip galvanizing upper coupler assemblies by allowing the kingpin to be installed after the galvanizing process,” said Jeffrey Talaga, SAF-Holland’s VP of sales and strategic development, Americas. “This design allows for the easy removal and replacement of the kingpin for dealers, fleets and OEMs.”

The system is compatible with ¼-inch, 5/16-inch, and 3/8-inch bolster plates, utilizing the same housing and different length kingpins to accommodate the thickness variations.
